    Growing concern over fossil fuel depletion and the environmental impact of greenhouse gases have driven the demand for solid biofuel energy as an alternative source of coal coke. Therefore, there is increasing attention on Bio-Coke as a new solid biofuel product. The moderate temperature with high loading pressure densification method shows the uniqueness of Bio-Coke, as it has a higher density and mechanical strength when compared to wood pellets and briquettes. These reasons are ideal properties for long-term storage and transportation to ensure the sustainable supply of solid biofuel. Moreover, Bio-Coke also has a stable structure at high temperatures (700 degrees C), making it suitable for many practical applications such as cupola furnaces. The potential utilization of Bio-Coke and the viability of Bio-Coke feedstock in Southeast Asia are described in this paper. The utilization of agricultural residues from the Southeast Asia region, such as coconut husk and oil palm frond showed a good quality of solid biofuel as it can exhibit a high calorific value of Bio-Coke. The paper also reviews the factors affecting the production process of Bio-Coke and the suggested methods for its mechanical property's improvement. Moreover, it reviews the economics of Bio-Coke and the impact of its utilization in the Southeast Asia region. Finally, implementing a low-temperature drying system is recommended to lower the production cost of Bio-Coke.

    Bio-coke is a solid biofuel with a high density and high compressive strength. Demonstration tests have shown that bio-coke can be used as an alternative to coal and coal coke. The effects of biomass type and production conditions on combustion characteristics have been studied for small diameter bio-coke (phi 50 mm or less). In this study, we focused on fuel size and investigated the combustion characteristics of phi 12 to 100 mm samples. Experiments were conducted in a preheated, forced convection atmosphere using a batch-type vertical combustion apparatus to simulate rapid temperature increase and combustion under isothermal conditions in a gasification and melting furnace or blast furnace. Two biomass species (Japanese cedar and green tea) were selected as materials to study the effect of biomass species. We developed experimental correlations to predict the combustion time of bio-coke, considering the effects of scale and aspect ratio. The flaming and char combustion times of bio-coke can be approximated using the shape factor (V/S)(n) even when the aspect ratios are different. We obtained that the characteristic length is (V/S) to the power of 0.52-0.64. Furthermore, we found that Japanese cedar bio-coke has 2.5 times faster in flaming combustion than green tea bio-coke.

    Effective utilization of biomass, including wood, is necessary for environmental sustainability. Bio-coke is a solid biofuel made from plant biomass. Bio-coke has been proposed as an alternative energy source to coal due to its high density and compressive strength. Bio-coke is produced by subjecting wood biomass to the hot press method, and the softening properties of hemicellulose and lignin in the raw biomass affect the formation, physical and mechanical characteristics of Bio-coke. In prior studies, we investigated the effect of raw material biomass composition and moisture content on flow-starting temperature, and compressive strength of the resulting Bio-coke. The purpose of the present study was to quantitatively determine the effect of biomass composition changes on flow-starting temperature and compressive strength on using cellulose-rich cedar trunk and lignin-rich cedar bark as raw materials. Due to the difficulty collecting a single form of biomass, the study of mixed raw biomasses is more relevant when evaluating practical applications of produced from these materials. The present study revealed that as lignin ratio increased, flow-starting temperature and Bio-coke compressive strength decreased. Furthermore, we developed a potential equation for estimating the maximum compressive strength of Bio-coke from the raw biomass chemical composition ratio and moisture content.

    One of the effective solutions to reduce CO2 emission derived from fossil fuels is the suppression of coal consumption in industrial boilers and power plants. Torrefaction is one of the promising treatments for reforming conventional solid biofuels, and torrefied solid biofuels have come to attract attention as an alternative to coal. When torrefied solid biofuels are utilized or produced, energy properties such as higher heating value (HHV) and energy yield of torrefied solid biofuels are quite important. In this study, to evaluate the energy properties for a given pyrolysis condition analytically, evaluation methods of HHV and mass yield of torrefied biomass based on isothermal pyrolysis kinetics are investigated for three biomass species, i) softwood; Japanese cedar, ii) hardwood; castanopsis and iii) herbaceous biomass; rice straw. There are two aims of the study. One is to present the HHV evaluation method by lumped-parameter pyrolysis kinetic models with high evaluation accuracy. The reduction in the mass yield due to torrefaction can be evaluated by the two-step pyrolysis kinetic model, and the HHV is provided with the mass fractions and heating values for constituent substances included in torrefied biomass of the two-step pyrolysis kinetic model. The other is to present the simple correlation to evaluate HHV without depending on three biomass species. From the comparison between the HHV evaluation method and experimental data, it is clarified that the proposed HHV evaluation method based on the two-step pyrolysis kinetic model can be useful to evaluate the HHV of torrefied biomass for three biomass samples with high evaluation accuracy, 5% or less. The linear correlation between HHV enhancement factor and mass yield of torrefied biomass is found regardless of three biomass species in the range of torrefaction mass yield larger than 0.6.

    This paper considers the possibility of applying indicators of coal as indicators of torrefied biomass characteristics. Used indicators of coal are fuel ratio which shows the combustion characteristics and coal band (van Krevelen diagram) which shows the degree of coalification. Torrefied biomass heated at different temperature are prepared by using green tea. Their changes of fuel ratio and chemical composition by coal band are considered. The results show the following findings. In the heating temperature from 293 K to 640K, fuel ratio is 0.38 to 2.07. There are the each negative correlation between yield of weight and fuel ratio when fuel ratios are a range of 0.38 to 0.65 and more than 0.65. When fuel ratio is 0.65, there is an inflection point. It is suggested that the volatile components released by thermal decomposition are different on the border line of the inflection point. By the application of coal band, chemical reactions are estimated during torrefaction process. However, it is difficult to decide what kind of reactions is occurring when the release of oxygen by decarboxylation and decarbonylation reaction and the release of hydrogen by demethanization and dehydrogenation reaction occur simultaneously.

    Bio-coke is highly densified biomass fuel developed early in this century. The first commercial sized manufacturing equipment, that materials are heated and cooled at same part in the reactor with press from one direction in batch typed operation, was installed in 2011. For saving the energy during manufacturing and construction cost, newly equipment have been developed. For the environmental impact assessment in particular global warming, life cycle CO2 that involves loading raw material, pretreatment, shaping Bio-coke, loading Bio-cokes and burning Bio-coke was calculated in the cases which Bio-coke was made by these equipment.

    Various sizes of high-density biomass briquette, named 'Bio-coke,' were produced from spent green tea grounds. The mechanical properties at room temperature of the Bio-coke samples were investigated using a compression testing machine. From the results, the relationship between the specimen size of Bio-coke and the ultimate compressive strength at room temperature showed that the ultimate compressive strength depends on the specimen size of Bio-coke. The maximum value of the ultimate compressive strength among the different specimen sizes of Bio-coke was at 67 MPa, obtained from the 12-mm diameter sample. In addition, at 12 mm diameter or smaller, there is hardly any difference in the ultimate compressive strengths measured. Hence, the cold compressive strength properties are divided into two groups based on the uniformity of the structure of the main components along the horizontal cross section of a Bio-coke. Results indicate that the state of the structure, composed of cellulose, hemi-cellulose, and lignin, appears to be consistent resulting from uniform permeation conditions at the 12-mm diameter or smaller samples. Meanwhile, at diameters of 20 mm or larger, the condition of the periphery of the samples were not consistent with that of the middle region because of the temperature, stress gradient and number of void occurring inside the Bio-coke caused by specimen size effect.

      In Fukushima prefecture, the full of temporal space for scrap wood, gathered deciduous leaf and wood contaminated with radioactive materials makes debris disposal not proceed now. It is considered that debris should be downsized and be stored safety until carrying to ISF (Interim Storage Facility). It is known that Biocoke has high density and poor reactivity, so we are confident that Biocoke technology is suitable to store the debris stably. In this study, leach of heavy metal and radioactive cesium from Biocoke into water was investigated in order to apply the Biocoke technology for storing debris for long time. An elution impact into landfill by combustion ash of Biocoke has been shown allowable value or less. In Elution testing of radioactive cesium from Biocoke to water, it could be demonstrated to suppress to 1/4 by Biocoke technology.

    We aimed to effectively use unutilized rice straw by producing Bio-coke, which is a new briquette (in the rest of this document referred to as the BIC) with high density and hardness, from rice straw with various conditions based on initial water content and processing temperature and evaluated characteristics of rice straw BIC. First of all, the apparent density of BIC was calculated from its weight and volume, and the cold compressive strength for each BIC was measured. From the results, it showed that the relationship between apparent density and maximum compressive strength derived from the compression test had a positive correlation. Furthermore, the hot compressive strength of the BIC produced with 5% initial water content and 453K processing temperature was measured. The rice straw BIC had a maximum compressive strength of 4.8MPa at a high temperature of 973K. This hot maximum compressive strength is equal to about one third of the hot maximum compressive strength of coal coke, which is 12MPa. Also, it was determined that the maximum compressive strength of rice straw BIC is highest on both cold and hot compression tests, and BIC produced from agricultural biomass like rice straw and rice husk had higher maximum compressive strength at room and high temperatures than BIC produced from other materials. Thus, it seemed that fiber and silica contained in agricultural biomass helps maintain of structure of BIC.

    People in the world have been eating rice for a long period of time, especially in Asian countries including Japan that considers rice as its staple food. Like many agricultural products, agricultural waste like rice husk and rice straw are a big disposal problem. One of the solutions for this problem is solidification. It is better to use the solid as fuel for heating and create a cycle of local production for local consumption. In this study, we established formation temperature and particle size as parameters and produced solid fuel (hereinafter referred to as BIC) from rice husk with high-density and high-hardness solidification technology. The apparent density from weight and volume of BIC and assessed compressive strength of BIC with compression test under room and high temperature was calculated. From derived results physical and mechanical properties were considered. Results showed that rice husk of small particle size had better lignin reaction than large one. However, it is also revealed that the maximum compressive strength at room and high temperature was both weak in the case of crushing the particle size of the rice husk too small.

    In recent years, the development of bio-energy in cooperation with an ASEAN country is a very important issue for both participating countries, which would be able to build a win-win relationship. ASEAN countries have a large amount of unused biomass resources. However, raw biomass business does not seem to work well based on experience unless a new technology is introduced. The Bio-coke (referred to as BIC) is a domestic energy technology in Japan. In this study, Bio-coke made from unused resources of fruits that are imported in large quantities from ASEAN countries is being focused. The compressive strength measured for Banana peel Bio-coke was 98.4 MPa at initial moisture of 1.81 mass% while the Orange peel Bio-coke measured 167.0 MPa at initial moisture of 0.52 mass%. Meanwhile, the apparent Yang's modulus ratio based on cool compressive test for the former is about 4.0 GPa and 4.5GPa for the latter. Through hot compressive test at 973 K, 8 MPa was recorded for Banana peel Bio-coke and about 4.2 MPa for Orange peel Bio-coke.

    Recently, biomasses attract much attention as a renewable energy resource. Biocoke, hereinafter called BIC, is one of the solid biomass fuels that are made from woody or herbaceous biomass by heat and compression processes. BIC is highly dense, has high hardness, has a high energy density, and is expected to be an alternative to coal coke. In the present study, the carbonization and combustion properties of a green tea BIC and a cypress BIC are experimentally examined. The experimental results show that the carbon residue of the BICs is higher than that of raw wood in spite being of the same material. Further, the weight reduction curve during the combustion process of the BIC carbide is similar to that of charcoal when the carbonization temperature is higher than 673 K. Consequently, it is considered that the BIC can maintain adequate hardness even if it is carbonized at the upper portion of a cupola furnace, and burns as an alternative to coal coke in the coke bed at the bottom of the cupola furnace.

    The high density high hardness solid fuel (bio-coke) developed by Ida et al. is being hoped for as a solid fuel for heating machineries such as a heavy oil farm boiler. The diameter of the bio-coke made in high pressure and high temperature has a range of 8mm to 100mm. In the case of the 100mm diameter bio-coke specimen, neither pressure nor the temperature is uniform because of thermal conductivity of the biomass and the friction against the cylinder wall. With these reasons, the qualities of the inside of the specimen do not become uniform. Through X-ray CT, nondestructive measurement of the spatial distribution of the x-ray absorption coefficient in the specimen can be done. The x-ray absorption coefficient changes depending on the density of the material, hence, the applicability of this procedure to estimate the X-ray CT quality distribution of a large bio-coke was examined. Results showed that the CT values obtained through X-ray CT have strong relationships with the density distribution in the specimen. Moreover, the CT values were confirmed to be able to effectively estimate the quality distribution of the inside of a large bio-coke.

      Currently, various energies such as fossil fuels and nuclear power are considerable expenditures. Resource depletion and environmental issues are taking place by activation of various problems and economic activity due to population growth in developing countries. However, in order for society to develop, energy, such as natural energy, is required have been studied for this purpose. A variety of energy including conventional type energy is needed. In this study, using Bio-coke that has attracted attention as a natural energy, a research was conducted using rice bran, which is an unused biomass in Thailand. By adding rice bran to 2-mm pulverized wood waste materials in making Bio-coke, it was found that Bio-coke density increased proportionally with increase in rice bran ratio. Results also showed that by adding rice bran in the raw material, it is possible to simultaneously improve both the gross calorific value and cold compressive strength. Moreover, reduction in environmental impact is also possible in the production process by optimizing the production conditions.

    A micro laminar premixed flame stabilized by an annular pilot flame is observed. The flame is formed even on a burner whose diameter is 0.3 mm. However, the shape of the flame formed on the burner whose diameter is less than 1mm and at around the lowermost flow rate is nearly spherical. It is similar to the appearance of a micro diffusion flame. The flame formed on the burner which has a diameter less than 1 mm is not considered a propagating flame, because a typical laminar propagating flame has a structure thickness that is more than 0.5 mm. The flame structure variation and the uppermost and the lowermost flow rates that the flame could be formed stably were observed. Consequently, it is supposed that the flame formed on a burner with a submillimeter diameter is dominated by the diffusion mixing of oxygen and methane from the main premixture flow, and heat and radicals from the pilot flow. The extinction mechanism of the micro premixed flame was examined and the scale effect on the extinction limit and the flame structure were considered.

    Primarily, Japan has very little sources of coal, oil, and natural gas. As a result these primary energy sources are imported from other countries. The development of Japans domestic primary energy sources is necessary to reduce its dependency on foreign energy import. Above all, energy derived from biomass sources are sustainable energy resources. In this study, various sizes of high-density biomass briquette named 'Bio-coke, whose technology was based on our patent (PAT.-No.4088933), were produced from green tea grounds. The physical properties at high temperature of each size of Bio-coke were studied, and their maximum compressive strength and Youngs modulus were estimated by a compression test at a temperature of 973K. From the results obtained, the relationship between the size of Bio-coke and the maximum compressive strength or Youngs modulus could be approximated by a linear function or an exponential function.

    A micro laminar premixed flame formed on a burner with pilot flame is observed. The flame is stabilized even on the burner whose diameter is 0.4 mm. However, the shape of the flame formed on the burner whose diameter is less than 1mm and at around the lowermost flow rate is near spherical. It is similar to the appearance of micro diffusion flames. On the other hand, the flame formed on the burner whose diameter is less than 0.6 mm is not considered as propagating flame, because typical laminar propagating flame has a structure more than 0.6 mm thickness at this condition. We observed the flame structure variation and the uppermost and the lowermost flow rates which the flame could be formed stably. It is, consequently, supposed that the flame formed on the burner whose diameter is submillimeter is dominated by the diffusion mixing of oxygen and methane from the premixture and high temperature heat flux from the pilot gas flow. We, further, examined the flame structure and the extinction mechanism of the premixed microflame and tried to explain scale effects on the extinction limit and the flame structure variation.

    This paper proposes the strategy or methodology how to achieve a scaling of flames; that is, the law to attain the ratio of flame size to flame thickness remains as constant in variety size of flame (thus, a larger flame has thicker flame zone while a smaller flame has thinner flame zone, yet the overall geometric similarity is sustained). Considering simple analysis the possible strategy to fulfill this requirement is discussed. It turns out that the combination with low-gravity and dilution would be key factors to attain the geometric similarity of the flame including its structure. We will verify this issue in future by means of low-gravity test facility (experimental approach) and numerical simulation with multi-step kinetics model (numerical approach).

    Biomass is one of the sustainable energy sources and is the most suitable natural energy for storage and transport. We are suggesting a high hardness biomass briquette made from any plant biomass as an alternative coal coke. The high hardness biomass briquette is named 'Bio coke', described as 'BIC' below, and it achieves 10 to 20% substitution of coal coke for practical cupola furnace use. We, in the present study, examined the influence of composition on combustion property of BIC made from coffee residues. The coffee residues were assorted to outer skin (outer skin and pulp mixture, described as 'OS' below), inner skin (parchment and silver skin mixture, described as 'IS' below) and coffee bean grounds (instant coffee production residue, described as 'IC' below). BIC specimens were composed of IC100%, IC50%+OS50% and IC50%+IS50%, OS100% and IS100%. Measurement of ignition delay (time from heating start to flaming combustion start), duration time of flaming combustion and char combustion, and thermogravimetry were conducted under 698K air environment. As a result, the ignition delay and the duration time of char combustion were affected by not only combustion property of each component but crack generation condition during heating process. The ignition delay and the duration time of char combustion were shorten due to enlargement of reaction surface area caused by the crack generation. It is, additionally, considered that the crack generation condition could be controlled by mixing of components which have different thermal decomposition and combustion properties.

    At present, Japan is even in a bigger energy problem since the oil crisis. Conversion to renewable energy has become an urgent need among many problems in Japan, one in particular, the carbon-dioxide emission that is increasing at an alarming rate. Bio-coke was developed in this laboratory and is reaching commercial level. This study discusses the relationship between the retention time of formed Bio-coke and its specific surface area. During the formation time of about 5 minutes, a specific surface area of 0.5 m<SUP>2</SUP>/g is achieved, and a cold compressive strength of 60MPa is attained. When the specific gravity reaches at least 1.395, the specific surface area is reduced to about 0.5 m<SUP>2</SUP>/g.

    The development of new energy sources have been advancing due to global warming and exhaustion of fossil fuels. The biomass fuel is one of these energy sources and is expected from the viewpoint of carbon neutral agricultural and biomass waste recycling and thermal recovery. Bio-coke is an alternate fuel of coal coke and is made by heating organic waste while being compressed at high pressures. The ignitability of Bio-coke worsens by high density. This study was an attempt to produce Bio-coke added with waste glycerin that is generated from the manufacturing process of bio-diesel fuel. The gasification characteristic of the fuels was examined by thermogravimetric analysis, while the stress-strain characteristic was examined by a high-temperature compression testing machine. The ignition and combustion characteristics of the fuels were observed in a fall-type electric furnace. Results show that Bio-coke can be made with the addition of waste glycerin. The gasification of the resulting fuel was promoted with the increase in amount of added waste glycerin. Moreover, the combustibility of the fuel was also promoted and the ignition delay time and burnout time became shorter.

    The utilization of unused biomass such as logging residues and broadleaf trees has come to attract attention to protect forests and satoyamas (a Japanese term for undeveloped woodlands near populated areas) in Japan. In this study, the modification of bio-coke fuels as an alternative to coal coke is investigated by using bamboo and Japanese cedar, which are the typical domestic woody biomass in forests and satoyamas. To improve the compressive strength under high temperature environment and the heating value of bio-coke, carbonized Japanese cedar is mixed with bamboo. The effect of the carbide mixture on the forming characteristics of bio-coke such as density, compressive strength, and heating value are experimentally clarified. The results obtained in the present study are as follows: (1) the density of bio-coke increases with increase in forming temperature and forming pressure, but is reduced by the addition of carbide as the thermoplastic polymer is reduced (2) the increase in carbide reduces the compressive strength under normal temperature environment and improves the compressive strength under high temperature environment. When the carbide content was 30%, the compressive strength under high temperature environment was 3.26MPa. (3) The addition of carbide is an effective way to improve the compressive strength under high temperature environment and to enhance the heating value of bio-coke.

    From the perspective of the matter cycle, a method to use biomass combustion ash as a fertilizer in the production of seedlings and silviculture is suggested. Ash from silica-rich biomass has high solubility due to its silicate microstructure, which makes it very effective as a fertilizer. However, the solubility is lost, along with the porous microstructure, when combustion ash is crystallized in a high temperature oxidative atmosphere. In addition, because the furnace is commonly made of stainless steel that contains chromic element and a high percentage of water is included in biomass, unlike fossil fuel, harmful hexavalent chromium may be found in the combustion ash. In this report, the progress of a study for the reduction of ash crystallization is described.

    The regulation governing organic waste processing has been enforced in recent years. For example, the enforcement of food recycling and emission control of livestock industry wastes has resulted in about 20 million tons of organic wastes produced annually in Japan. As well, Aomori prefecture has been holding grave problems which hang low of local area economic and doesn't find out effective solution for unutilized biomass. This study is based on alternative coal coke technology which the authors developed. The method of production technology of Bio-coke follows our patent (PAT.-No.4088933). In this study, we used an apple juice grounds as unutilized biomass in Aomori prefecture to produce Bio-coke. We discuss the relation between cold and hot compressive strength derived by the new proposal compression test.

    The aim of the lapanese cabinet council's 'Biomass Nippon Strategy' is to increase the utilization of biomass as one of the ways to reduce the dependence on fossil resources. However, there are various problems associated with the use biomass, one of which is the cost associated with the collection and transportation of biomass. Biomass has high moisture content and low bulk density. The biomass solidification technology developed by Ida et al. partly aims to solve the transportability problem. This study shows physical properties of high density and hardness of the new briquette produced from herby biomass. The relationship between apparent density and maximum compressive strength and an effect on the maximum compressive strength by black colorization are considered. Also, an attempt is made to explain the effect on properties of the briquette by hemi-cellulose and lignin in the region before semi-carbonized region. As a result, the relation between the apparent density and the compressive strength shows that maximum value exists as characteristics of the herby briquette. The maximum apparent density for all processing conditions is 1.38 g/cm3 at the initial moisture 0.10 kg/kg-wet -processing temperature 473 K. The maximum compressive strength for all processing conditions is 127 MPa at the initial moisture 0.05 kg/kg-wet -processing temperature 453 K. Furthermore, the effect of black colorization indicates that when the area of black colorization is increased for the surface of herby biomass briquette by increased in the processing temperature, the maximum compressive strength is decreased due to reduction in the adhesion of lignin. Consequently, high-density and high-hardness of the new briquette can be controlled by the initial moisture and the processing temperature.

    Micro-jet diffusion flames, formed by a minute burner of a few hundreds or a few tens micrometer inner diameter, should be interesting and useful, partly because they resemble micro-gravity flames and partly because they provide some insight into the mixing and chemical kinetic processes occurring in turbulent diffusion flames. The aim of the present experiment is to collect preliminary information on the characteristics and experimental techniques of micro-jet flames. Attention was paid to the effect of Reynolds number (Re) at the burner exit, and the range of Reynolds number that a stable flame could be formed was determined. CH-band images were recorded by direct photography, and compared with laser shadowgraph images.

    We produced high-density solid biomass (hereafter called Bio-coke) from broccoli, dead cherry tree leaves, and seed of mango based on our patent (PAT.-No.4088933) as one of the utilization methods of various unutilized biomass. The compressive strength of each kind of Bio-coke under room temperature was measured with a compression testing machine. The experimental results showed that the ultimate strength was related to the carbon content of broccoli, seed of mango, and dead cherry tree leaves, and the relations were close to linear.

    The fuel jet velocity at the extinction limit of a jet diffusion flame can be as large as that at the blowoff limit under microflame conditions, requiring detailed understanding of extinction mechanism. This paper first discusses a simple theory to describe the extinction mechanism of jet diffusion microflame. An activation-energy asymptotics technique is adopted with the use of constant-density approximation to predict the extinction limit. Results of experiments for different burner diameters are then presented to compare theoretical predictions with experimental observations.

    The potential of biomass resource is equivalent of approximately 5% of the primary energy aggregate supply in Japan if available untapped biomass resource can be used effectively. Therefore, the unused biomass resource is expected to reduce the degree of dependence to fossil resources. In this study, we targeted woody biomass, agricultural residues and food waste which occupied a large part of annual available quantity of energy and produced high-hardness solid fuel (named Bio-coke) from various kinds of biomass with heating and pressing method based on our patent (PAT.-No.4088933). We have measured the compressive strength of Bio-coke to derive its physical properties at room temperature, and also examined the physical properties of Bio-coke at high temperature (973K) with a particular compression testing machine as assuming its usage under high temperature atmosphere. We contemplated the relation between the compressive strength at room temperature and high temperature for Bio-coke. As a result, there are not any relationships between the compressive strength at room temperature and high temperature. It is conjectured that the difference of the compressive strength between room temperature and high temperature proceeds from the component percentages and organization structure of cellulose, hemicellulose and lignin for each biomass

    Coal-coke is required a lot of performance in a melting furnace. Therefore, Coal-coke has 2OMPa of high mechanical compressive strength under room temperature, cold strength. The high mechanical cold compressive strength is very important factor for Bio-coke (named at Kinki University) as the substitution for Coal-coke. Especially, Bio-coke is required itself performance for mechanical compressive strength to keep air passage into the melting furnace as well as Coal-coke. This study proposes a simple nondestructive method for hardness evaluation with Bio-coke produced from apple juice residue, mainly non-utilization biomass on Aomori Pref. The mechanical properties have been measured by Brinell hardness and cold compression test to obtain the fundamental database with production conditions, initial moisture, process heat temperature, etc. In particular, the cold hardness of the Bio-coke is influenced by process heat temperature. This study suggests that Brinell hardness test can apply effective means as a simple and easy evaluation method of the Bio-coke in comparison with the cold compression test.

    Flame structure of micro scale methane-air premixed flames is investigated experimentally. The flame is stabilized even on the burner whose diameter is 0.3mm when it is with pilot flame. However, shape of the flame formed on the burner whose diameter is less than 1mm is similar to micro diffusion flame. It is supposed that the flame formed on the burner whose diameter is submillimeter is dominated by the diffusion mixing of oxygen and methane from the premixture and heat and radicals from the pilot gas flow.

    Various conversion technologies of biomass have been created since the development of utilization technology of biomass was worked on in 2000. However, the innovation conversion technologies created by the development still have problems of high water content and low density, which are negative points on usage of biomass. From the viewpoint of density of biomass, we crushed molecular space of biomass without carbonization and semi-carbonization. In this study, we measured internal thermal conduction of high-density solid biomass, closing asymptotically to true specific gravity 1.4 of biomass and investigated the characteristics of internal thermal conduction. It is shown that the value of dT/dr which shows spatial thermal gradient constantly increases with time course and not by depending on conditions. Also, it is shown that the dT/dr takes the ultimate value 380K/m and gradually decreases after taking the ultimate value.

    Bio-cokes, developed by Kinki University (domestic patent No. 4089933), can utilize unused biomass and be used as a coalcoke substitute in large-scale industrial processes such as foundry cupola furnaces. Bio-cokes are expected to serve as a technology corresponding to (1) reduction in the amount of the CO2 generation for the global warming prevention; and (2) rise of the price of coal coke.
    In preliminary tests conducted at Kinki University, it was confirmed that Bio-cokes could be manufactured from various raw materials such as used tea leaves, wood waste, etc. This paper reports our current effort to optimize manufacturing conditions of a mass-production facility of Bio-cokes.
    This study confirms the pressured solidification characteristics of biomass (using tea scum as the raw material) with varied parameters such as heat process temperature, smashed size, pressure, and initial water content. Thermal analysis of the material explains why the manufacturing process does not change material weight when setting the heat process temperature at 180°C . The optimum pressure for effectively obtaining a high specific gravity is constantly around 20MPa in spite of different smashed material sizes. There is the optimum initial water content to achieve the highest specific gravity, which is very close to the value based on the true-densiy.

    Global environment problems have become more and more serious in recent years, and reduction of greenhouse gas emission based on Kyoto Protocol adopted at the 3rd conference of the parties of the United nations Framework Convention on Climate Change (COP3); securement of primary energy source and development of clean and renewable energy sources have been pressingly needed in consideration of the predicted depletion of fossil fuel in the future.
    In this study, we explore the use of a solidified biomass-derived fuel, having the maximum compressive strength of 100MPa and calorific value of 21MJ/kg, in iron-casting or iron-making processes as an alternative fuel to be mixed with coal coke. This study, carried out for internal observation using a quick-freeze technique, observed an actual working cupola furnace under the 20% alternative coal coke operation condition. After quick freeze of the cupola furnace, the solidified biomass fuel was found to inhabit near the iron-melting zone. Especially, this solidified biomass fuel smoothly changes carbonized fuel through high-density state during the operating process. On the other hand, this study tried to simulate gasification combustion under a high temperature environment instead of actual internal combustion of solidified biomass fuel. These combustion mechanisms were confirmed to be similar to diffusion-flame phenomena in general.

    This paper presents a theory to predict the extinction limit of laminar jet diffusion microflames, defined as flames established on submillimeter-diameter burners. The classical Burke-Schumann (BS) theory is first extended to include the effect of one-step, finite-rate chemistry. Then, a theory of diffusion-flame extinction is applied using activation-energy asymptotics to predict the extinction limit. The present theory correctly reproduces experimental observations, i.e., uL ∼ d-2, where uL is the fuel jet velocity at the extinction limit (lower limit) and d the burner diameter. According to the BS theory, the gradient of mixture fraction at the flame-sheet location is infinite at the burner rim, and it decreases with increasing axial distance to the minimal value at the flame tip. Therefore, local extinction initiates at the burner rim, and extinction occurs when the mixture-fraction gradient at the flame tip is greater than a critical value. This view of microflame extinction is supported by the results of experiments and numerical simulations. It is found that the present theory can be applied for various types of fuels, those are, methane, propane, and butane. © 2009 The Combustion Institute. Published by Elsevier Inc.

    Effective utilization of biomass resource rapidly has been promoting since the government adopted the 'Biomass Nippon' strategy at a cabinet meeting in 2002. Especially, the energy conversion technology of applying biomass has been expected from a point of view of environment and resource conservation. However, the energy conversion technologies are developed only for woody and herby biomass, and not for all of biomass. A stable supply of large quantity of biomass will be pressed in the future because the conversion technology must expand to use a variety of biomass. This study is to consider ways by various quantitative correlation analyses between the atomic composition and thermal decomposition of various biomass samples. The results found that thermal decomposition analyses of various biomass resources have correlations between atomic composition properties and exothermic properties.

    In Japan, 7.50 million tons of rice straw was incinerated and plowed under soil. This abundant resource of rice straw is useful as alternative energy for recycling-based societies and also in possibly activating agriculture that is dependent on local production for local consumption. We aimed to effectively use unutilized rice straw by producing Bio-coke, which is a new briquette (in the rest of this document referred to as the BIC) with high density and hardness, and evaluated characteristics of rice straw BIC because the relationship between specific gravity and specific surface area of BIC is not well known. Additionally, it is seems that the specific gravity and specific surface area at the periphery of BIC may affect its combustion characteristics. In this study, one of the aims is that BICs are produced with various specific gravity and specific surface area as a parameter. It was confirmed to be able to produce BIC with different specific gravity and specific surface area at the periphery of BIC by changing manufacturing conditions of BIC and be led the relationship between the specific gravity and the specific surface area. After that, it was examined that difference of the specific gravity or the specific surface area at the periphery of BICs relates the ignition delay time as one of the combustion characteristics derived from burning BIC with different specific gravity. As a result, it was led that the relationship between the specific gravity or the specific surface area at the periphery of BICs and the ignition delay time was a direct proportional relationship.

    Fossil fuel, like oil, coal, natural gas and so on, has sustained our local infrastructure on the side of Energy. However, the fossil fuel has various problems at the point of the quantity of resources and environmental burden. We need to rapidly develop sustainable energy resources to substitute for the fossil fuel. In this study, we tried to measure combustion characteristics of alga of Lake Biwa Bio-coke. Bio-coke is a fuel as an alternative energy source to coal. We derived that alga of Lake Biwa has a lot of ash, including about 25%, in comparison with other land biomass from the result of thermal decomposition characteristics. Concerning the combustion characteristics, ignition delay time for alga of Lake Biwa BIC is about one and a half times longer, and flame and char combustion time is shorter than Japanese cypress BIC. Thus, although the BIC produced from alga of Lake Biwa has many demerits for combustion performance, the research of alga BIC as adiabatic material is expected as a next step.

    一般的に表面燃焼は酸素あるいは酸化ガスが固体表面や内部に拡散することで起こる現象であるが、内部に空隙がない固体では酸素などの拡散が生じないため表面燃焼は持続しない。さらに、固体の密度を高めていくと普通にバーナーであぶる程度では着火現象は起こらない。このように、固体燃焼は密度による影響を受けることが知られているが、密度を変化させたときの固体燃焼挙動は知られていない。本研究では、着火し、かつ表面燃焼が継続する線香の密度（0.7~0.9 g/cm3）から固体燃料である薪などのバイオマスの真密度である1.5 g/cm3まで密度を変化させたときの固体の着火限界を定量的に調べることを目的とした。また、密度の異なる固体を燃やしたときの表面燃焼を撮影することにより、固体燃焼が継続する時間を確認し、また内部への燃焼の伝播の様子についても観察を行った。

    Low Carbon Society started based on a new concept by METI in JAPAN. A low carbon project has many programs, transportation or carbonization technologies and dust division motion act etc. Our projects carried out feasibility studies of alternative energy for fossil resources with the new solid bio-fuel, Biocoke. Biocoke has special physical properties of high density and hardness. One of our projects is that this report discusses the mono-fuel combustion boiler developed exclusively for Biocoke. The herbaceous plant, Itadori, is used as a biomass raw material to produce Biocoke. The Biocoke boiler has the hybrid thermal exchange system by hot water and air as itself performance. On the other hand, this project proposed a new thermal energy distribution system based on planter agriculture for high efficient utilization of thermal energy. The total thermal efficiency of Biocoke boiler is 75% over at the maximum. In winter, Biocoke boiler worked in high performance condition during 5 months under the extremely cold environment at -30℃. This project suggested Biocoke is able to completely substitute for fossils resources such as kerosene/heavy oil. Accordingly, this project found that Low Carbon Society can realize by high value added industry and low carbon agriculture under economic action in the winter season.
