Full textAbstract:
Burning fossil fuel like coal in power plants released carbon dioxide that had been absorbed millions of years ago. Unfortunately, excessive carbon dioxide emission had led to global warming. Malaysia, as one of the major exporters of palm oil, has abundant oil palm mill residues that could be converted into value-added product like biomass fuel briquettes. Fuel briquette with palm kernel shell and palm mesocarp fibre as its main ingredients showed satisfactory fuel characteristics and mechanical properties as a pure biomass fuel briquette. The effects of adding some coal of higher calorific value to the satisfactory biomass fuel briquette were focused in this study. Various coal-biomass fuel blends were used, ranging from 0wt% coal to 50wt% coal. The fuel properties and mechanical properties of pure biomass briquette and briquettes with different amount of coal added were compared experimentally. From the fuel properties tests, it was found that as the coal content in the briquette was increased, the carbon content and calorific value increased. Mechanical property tests on the fuel briquettes showed a mixture of results, with some favored higher portion of coal in the briquette for better handling, transport and storage properties while some favored greater amount of biomass.

The technological innovation of electric briquette stove is one of the latest innovations in an effort to increase the use of environmentally friendly renewable energy. The electric briquette stove has two functions, namely the means for combustion systems with biomass briquettes only, or if biomass briquettes are not available it can function as an electric stove only. This technological innovation has the main goal of improving the function of the stove, especially from the fuel side. It is expected that with the electric briquette stove the community will be more interested in using stoves with environmentally friendly fuel in this case biomass briquettes and have alternative fuels other than LPG gas at a more economical price. The importance of this technology is disseminated to the people of Tangkil Village, Citeureup, Bogor because the attractiveness of the people to use briquettes is still low, so the dependence on LPG gas is still quite high.

The measuring has proved that the energy herbs can be pressed into the form of compact briquettes. It regards 9 varieties of the energy crops, i.e. coriander, crambe, saphlor, sorrel, sorghum, reed canary grass, knotweed, barley straw and rapeseed straw. These energy crops are disintegrated by the grinding mill ŠV 15 (manufacturer Stoza, Ltd.) before the pressing. The fraction size is given by the mesh size of circular cross section of diameter 15 mm. All the crops have constant moisture content during the measuring and uniform diameter 65 mm of the resulting briquettes. The biomass moisture ranges from 9 to 11%. The pressing is conducted by the briquette press HLS 50 (manufacturer Briklis, Ltd.). The measuring results have shown the highest volume weight in following energy herbs: coriander, saphlor, rapeseed straw, sorghum, sorrel and knotweed. The lowest volume weight was found in these crops: reed canary grass, crambe and barley straw. The measuring proved that the highest force for the briquette disintegration is necessary for knotweed, saphlor, sorrel, sorghum and coriander. The lowest force for the briquette disintegration needs the reed canary grass, barley and rapeseed straw and crambe. Crambe contains a high level of oil in its seeds and this fact causes difficulties during their pressing as good mechanical parameters regards, thus they cannot be pressed into the briquette form.

Full textAbstract:
In order to utilize the agro residues and non-edible oil seed shells for the energy purpose, Areca Nut Husk (ANH) and Simarouba Seed Shell (SSS) are considered as raw materials and pulp production industry byproduct Black liquor (BL) as a binder for the production of fuel briquettes. The cylindrical briquettes were produced in four different blending proportions at 3 different pressures between 60 MPa to 80 MPa and various briquette properties were evaluated. The mathematical regression equations between the independent variables (blending proportion and compacting pressure) and briquette properties were developed. The R2 values for the regression equation between independent variables and (Briquette properties) compressed density, relaxed density, relaxation ratio, shattering index and compressive strength were 0.945, 0.743, 0.646, 0.862 and 0.839 respectively. The results confirmed that briquette produced with a blending proportion of ANH:SSS:BL=60:40:00 at 80 MPa have better properties. Thus, combustion characteristics such as proximate analysis, ultimate analysis, calorific value were estimated for a briquette produced with a blending proportion of ANH:SSS:BL=60:40:00 at 80 MPa; and compared with Barley and Sawdust charcoal briquettes. The overall results conclude that better quality briquettes can be produced from the blends of ANH and SSS and can be used for several heating applications.Article History: Received Dec 15th 2017; Received in revised form May 16th 2018; Accepted June 3rd 2018; Available onlineHow to Cite This Article: Ujjinappa, S. and Sreepathi, L.K.

Full textAbstract:
Biomass is an alternative renewable energy sources that can generates energy almost same as fossil fuel. The depletion sources of fossil fuel had increase the potential use of biomass energy. In Malaysia, rice husk and banana residues are abundantly left and not treated with proper disposal method which later may contribute to environment and health problems. Thus the development of biomass composite briquette made from rice husk and banana residue is one of the potential ways to reduce the problems and hence may contribute the better way to treat the waste by recycling the waste into a form of biomass product. The biomass briquettes are used for thermal applications because it can produce a complete combustion as it has a consistent quality and high burning efficiency. However, the quality of the biomass briquette can be added by application of torrefaction pre-treatment method. Torrefaction is a thermal method that can produce more high quality of the briquette with high calorific value, high fixed carbon content, low volatile matter, and low ash content. This study was conducted to assess the physical and combustion characteristic of the biomass briquette from rice husk and banana residue which was produced through torrefaction process. The biomass briquette, were densified by using hot press machine with temperature of 180°C for about 30 minutes. The briquette produce are 150 μm in particle size with varies in mixing ratio of rice husk to banana residue which are 100:0, 80:20 and 60:40. After the briquetting process, the biomass fuel briquettes have been undergoes parameter testing and the data have been analysed. Result showed the best biomass briquette is developed from torrefied rice husk and banana residue mixed at ratio of 60:40. Moreover, SEM image reveal that torrefaction pre-treatment has shrinkage the fibres size which confirming the thermal stability of the briquette.

The results of studies of changes in the fractional composition, calorific value and structure of lignin as a component of the fuel briquette as a result of mechanical activation based on the interpretation of experimental research data are given in the article. Criteria for mechanical activation are proposed. To identify the joint effect of mechanical activation time and the proportion of technical in the composition of the briquette, the experiment planning method was applied. As a result of data processing, a regression equation was obtained for predicting the calorific value of briquettes from the lignin content and the time of its mechanical activation, and its adequacy was proved. The developed methods and criteria for evaluating the results of thermogravimetric studies allow us to predict the efficiency of mechanical activation and the calorific value of technical hydrolysis lignin as a component of fuel briquette. At the same time, by varying the compositional composition and technological parameters of briquetting, it is possible to predict the production of fuel briquettes of required quality from wood waste.

Mushroom farmer society Sedyo Lestari is located in the Argosari, Sedayu, Bantul. The high demand for mushrooms media (baglog) is a good business opportunities for this farmer society. But the process of baglog making requires a lot of energy in the form of firewood, especially for sterilization process of the baglog. On the other hand, the mushroom cultivation process itself remains the waste that can be used as fuel for the sterilization process. So far Sedyo Lestari farmer society members do not have the technology to used the mushroom cultivation waste as a fuel. Therefore, it is imperative to transfer knowledge of biomass briquetting technique. The method used in this activities are socialization, training, and mentoring by starting with the introduction of briquettes and briquetting technology. Subsequently made briquette-making machines followed by training briquette making. Mentoring and socialization were also made to all members of farmer society. Outcome of these activities was briquette-making machines that can be used by all members of the society as well as knowledge about the process of making briquettes. The benefit of using briquettes of mushroom cultivation media waste as fuel for subtitute the firewood can provide savings to the expenditures of farmers for buying firewood and solving the waste management problems for farmers.

Global waste generation has been a challenging issue that vastly affects humans and the environment. The conversion of a vast amount of agricultural and polymeric waste to briquette may bridge the energy deficit and environmental pollution issues in developing economies. On the other hand, the utilization of biomass waste or residue as an energy source could help alleviate dependence on imported energy and its use continues to be a topical issue in both developing and developed countries. Over the years, biomass has been an important source of generating energy due to its relative availability and the ability to meet both heat and electricity demands by contributing towards international commitments so as to minimize environmental degradation and maximize environmental, social, and economic sustainability. The benefits of compacted biomass compared to all other types of biofuel include its low transportation and storage costs, uniform product quality such as constant humidity content, and high mass fluency. Moreover, fuel wood and biomass residues have low combustion efficiency, posing environmental and health hazards. This research studies the performance of briquettes produced from maize cob, sugarcane bagasse, and polythene waste composites. The briquettes were agglomerated using cassava starch binder (CSB) and plantain peel binder (PPB) at binder concentrations of 4%, 12%, and 20%. Each briquette was characterized in terms of proximate analysis, calorific value, ultimate analysis and micro-structure by scanning electron microscopy. The briquettes had a moisture content of 5.39-12.10%, volatile matter of 10.15- 23.08%, ash content of 10.29-24.63%, fixed carbon content of 55.84-77.10%, calorific value of 9.04-28.14 MJ/kg, carbon content of 77%-8405%, nitrogen content of 0.875-1.05%, and sulphur content of 0.4-0.7%. The results obtained from this study revealed that briquette produced using CSB at binder concentration of 4% had the best properties required for biomass fuel briquette compared to briquette produced using PPB and suggested its use for the production of environmentally friendly solid fuel.

Mikania micrantha (mile- a-minute in English) is assessed as one of the six high risks posed IAS in terrestrial ecosystem in Nepal and is as a considered second biggest threat after deforestation to biodiversity conservation. It is becoming pervasive and estimated to have covered over 20% of the Chitwan National Park. A survey was conducted jointly with NTNC, TCN and NAST to establish the estimates of available Mikania biomass raw material. After being cut, it can even regenerate by old rootstocks, runners and suckers. It does not have much use after manual removal. So, using dried biomass for briquetting to get fuel may be an option for its utilization. Different types of briquettes using biomass as well as char were made from its raw materials. Various physical and fuel characteristics of the briquette fuels and combustion tests were performed and studied as an alternative fuel. Different test results show that the use of this weed to produce briquette fuel will generate a potential source of alternative energy and will also help in conserving biodiversity in long run.

The residents of Nairobi, Kenya, use 700 tonnes of charcoal per day, producing about88 tonnes of charcoal dust that is found in most of the charcoal retailing stalls that is disposed of inwater drainage systems or in black garbage heaps. The high costs of cooking fuel results in poorhouseholds using unhealthy materials such as plastic waste. Further, poor households are opting tocook foods that take a short time to prepare irrespective of their nutritional value. This articlepresents experiences with community self-help groups producing charcoal fuel briquettes fromcharcoal dust in poorer nieghbourhoods of Nairobi for home use and sale. Households thatproduced charcoal fuel briquettes for own use and those that bought them saved 70% and 30% ofmoney spent on cooking energy respectively. The charcoal fuel briquettes have been found to beenvironmentally beneficial since they produce less smoke and increase total cooking energy bymore than 15%, thereby saving an equivalent volume of trees that would be cut down for charcoal.Charcoal briquette production is a viable opportunity for good quality and affordable cooking fuel.Bioenergy and waste management initiatives should promote recovery of organic by-products forcharcoal briquette production.

Municipal solid waste (MSW) and charcoal can be used as a substitute fuel in a gas engine. In this work, performance of a downdraft gasifier and gas engine system operated on MSW briquette fuel was investigated. Experimental test was carried out on a 62 kW, four-cylinder, naturally aspirated engine coupled to a 20 kW dynamometer. The downdraft gasifier was used to generate producer gas from MSW briquettes and charcoal. The engine load was varied between 1.5-9.0 kW. Biomass consumption, producer gas production, cold gas efficiency, thermal efficiency of the gas engine, carbon monoxide (CO), hydrocarbon (HC) emissions and exhaust temperature were evaluated. The MSW briquette fuelled operation was compared against that with charcoal. It was found that, the use of MSW briquette led to lowering performance of the downdraft gasifier and gas engine system, in comparison with the use of charcoal. Maximum cold gas and thermal efficiencies obtained were 64.6% and 16% at 4.5 kW and 9 kW loading, respectively. The CO and HC emissions of the gas engine operated on MSW briquettes were higher than that on charcoal, while the exhaust temperatures were similar. ©2019. CBIORE-IJRED. All rights reserved

Oil palm frond is one of the most potential biomass solid fuel sources for heat and power generation. Processing of oil palm frond into solid fuel created underutilized and neglected residues in the forms of fiber, grains and sawdust. Fuel briquettes of 10.5 cm in diameter and 2.5 cm in thickness were formed from the residues using a hand press briquette maker and tested as solid fuel for gasification. With a specific density of 40 kg/m3 and an equilibrium moisture content of 12±1.5% by dry basis, the briquettes were found to pass extensive drop tests and were able to produce syngas consisting of 8.1% CO, 11% CO2, 2.1% H2 and 0.5% CH4 through gasification. Successful syngas ignitions were obtained from the updraft gasification of the briquettes, showing the briquettes potential as a prospective solid fuel for heat and power generation.

The present study deals with the issue of bio-briquette fuel produced from specific agriculture residues, namely bamboo fiber (BF) and sugarcane skin (SCS). Both materials originated from Thừa Thiên Huế province in central Vietnam and were subjected to analysis of their suitability for such a purpose. A densification process using a high-pressure briquetting press proved its practicability for producing bio-briquette fuel. Analysis of fuel parameters exhibited a satisfactory level of all measured quality indicators: ash content Ac (BF—1.16%, SCS—8.62%) and net calorific value NCV (BF—16.92 MJ∙kg−1, SCS—17.23 MJ∙kg−1). Equally, mechanical quality indicators also proved satisfactory; bio-briquette samples’ mechanical durability DU occurred at an extremely high level (BF—97.80%, SCS—97.70%), as did their bulk density ρ (BF—986.37 kg·m−3, SCS—1067.08 kg·m−3). Overall evaluation of all observed results and factors influencing the investigated issue proved that both waste biomass materials, bamboo fiber and sugarcane skin, represent suitable feedstock materials for bio-briquette fuel production, and produced bio-briquette samples can be used as high-quality fuels.

Villagers of Delo and Raekore have a traditional eucalyptus refining business by boiling the eucalyptus leaves for aromatic oils. Eucalyptus oil produced quite well, it's just a long distillation process that is 5 to 6 hours so it requires a lot of wood. While the availability of firewood in the forest is currently quite difficult, so people often cut down trees in the forest. So need to find a solution by changing the way of boiling by steam method and using charcoal fuel made from coconut shell, because it has a higher calorific value than the shell is burned directly. Traditional refined eucalyptus oil products, ranging from 2 to 3 beer bottles (1 bottle of beer = 350 ml) per day, so that through the activities of IbM can apply the appropriate technology products that is the installation of wood crude oil refinery by steam method and the using of briquette fuel. The steamed container produced has a volume of 160 liters while the charcoal briquette printing device is capable of printing 8 charcoal briquettes in one print. The using of refinery installations by steam method and charcoal charcoal fuel, can increase the production capacity of eucalyptus oil to encourage economic improvement of Delo and Raekore villagers. The eucalyptus refining oil refinery has a production capacity of 4 to 5 bottles of beer (1 bottle of beer = 350 ml) per day and charcoal briquette presses have a production capacity of 8 charcoal briquettes.

The present study investigates the quality changes of wood bio-briquette fuel after the addition of spent coffee ground (SCG) into the initial feedstock materials (sawdust, shavings) in different mass ratios (1:1, 1:3). Analysis of SCGs fuel parameter proved great potential for energy generation by a process of direct combustion. Namely, level of calorific value (GCV = 21.58 MJ∙kg−1), of ash content (Ac = 1.49%) and elementary composition (C = 55.49%, H = 7.07%, N = 2.38%, O = 33.41%) supports such statement. A comparison with results of initial feedstock materials exhibited better results of SCG in case of its calorific value and elementary composition. Bulk density ρ (kg·m−3) and mechanical durability DU (%) of bio-briquette samples from initial feedstock materials were following for sawdust: ρ = 1026.39 kg·m−3, DU = 98.44% and shavings: ρ = 1036.53 kg·m−3, DU = 96.70%. The level of such mechanical quality indicators changed after the addition of SCG. Specifically, SCG+sawdust mixtures achieved ρ = 1077.49 kg·m−3 and DU = 90.09%, while SCG + shavings mixtures achieved ρ = 899.44 kg·m−3 and DU = 46.50%. The addition of SCG increased wood bio-briquettes energy potential but decreased its mechanical quality. Consequently, the addition of SCG in wood bio-briquette has advantages, but its mass ratio plays an important key role.

Combustion of coal, a fossil fuel, in power plant, is a major source of carbon dioxide emission, a greenhouse gas that causes global warming. Malaysia is one of the major exporters of palm oil and has 421 palm oil mills operating in 2010. Some of the residues from these mills like palm kernel shell and palm mesocarp fibre were converted into value-added products. An optimum biomass fuel briquette was obtained with palm kernel shell and palm mesocarp fibre as the major ingredients. Co-firing coal with biomass is a possible approach for power plant to curb the excessive emission of carbon dioxide. In this study, bio-briquette having 50% coal and 50% biomass which consisted of the ingredients of optimum biomass fuel briquette were studied in details. Comparison of the fuel properties, combustion characteristics and carbon dioxide emission between the optimum biomass fuel briquette and bio-briquette was made.

The yields of combustible gases (H2, CO and CH4) from Rice husk briquette were observed to be generally higherthan those of groundnut shell with sawdust briquette. The result with Groundnut shell and Sawdust briquette as input indicatedthat the fraction of H2, CO and CH4 gradually decreased, while the concentration of CO2 and H2O increased when moisturecontent increases from 0% to 45%. Similar trend was observed from the analysis of Rice husk briquette gasification in the model.The amount of Air per kmol of fuel varied from 0 to 1.0. As a result, the H2, CO and CH4 content of syngas for Groundnutshell and sawdust briquette decreased continuously; with CH4 approaching zero at air/fuel ratio of unity. Similar trend occurredin Rice husk briquette, but the values were higher than those observed for the groundnut shell & sawdust briquette.

Characteristics of Particulate Emissions from Co-Firing in An Industrial Boiler. PT. X is a textile industry that consumes a massive amount of coal for its boiler operation. It requires substantial costs to obtain coal from Sumatra and Kalimantan. An alternative solid biofuel (briquette) was developed to combine bottom ash and biomass made from municipal solid waste called Biomass Coal Fuel (BCF) briquette. The purpose of this study is to measure the total concentration of particulate matter and emission factor (PM) emitted from two burning experiments: only coal (100%) and mixed coal fuel with 10% of BCF (co-firing). Mixed coal and BCF burning are carried out in the fire-tube boiler where the PM emission is released through the stack. The Center for Pulp and Paper measured particulate emission with methodology referring to SNI 7117.17-2009. Particulate matter concentration emitted from only coal-burning was 12,1 mg/Nm3,but when mixed BCF and coal were used, the higher concentration was emitted 70,9 mg/Nm3. The addition of BCF briquettes affects the particulate matter emission, even though the emission does not exceed the regulated quality standard. The increase of particulate concentration is due to the BCF briquette characteristics, which have a low heating value and high ash content. The boiler has already been equipped with cyclone and wet scrubber; therefore, PM emissions presented here are treated emissions. The controlled PM emission factor of BCF was 4,46 g/kg, which is higher than only coal which was 0,51 g/kg. BCF briquette can still be used as co-fuel for the boiler, but further effort is still required to reduce the ash content of the BCF and increase the calorific value of the BCF.

An experiment was conducted on densification processing of sorghum straw stalks with self-made steel molds on a hydraulic universal test platform. The influences of different densification conditions on physical quality of briquette fuel are investigated, including pressures, temperatures, moisture contents and straw preheating method. Moreover, the relationship between molding temperature and inner stress decreasing rate of straw briquette at holding pressure stage is also analyzed. The result shows that the suitable value of moisture content, temperature and molding pressure for straw compression process is 20%, 90°C and at least 50MPa, respectively. The phenomenon of uneven temperature distribution in straw briquette keeps in existence even in the case of microwave preheating. However, in contrast with the very low central temperature in straw briquette when preheating by electric heater wire, the phenomenon of local overheating caused by microwave preheating may be helpful to straw molding process.

A variety of plant and animal resources (waste) can be used as biofuel. The use of biofuel is less profitable than fossil fuels, so many countries introduce special subsidies to encourage their consumption. However, to obtain these subsidies, it is necessary to prove that companies, in case of purchasing imported materials, buy them in countries that support the principles of the current climate agreement. Unlike the United States, which left the Paris climate agreement, Russia has ratified it. This means that European companies have a strong economic interest in purchasing biofuel from Russia, and not from the United States. And Russian timber companies are increased in their motivation for the efficient processing of waste of their main production into a popular export product — fuel pellets and briquettes.

This research characterized briquettes made with Pinus spp. sawdust without the use of additives. For this purpose, 19 samples of sawdust from different wood industries located in five states of the Mexican Republic were used. The densification process was carried out in a vertical hydraulic piston laboratory briquette machine. The briquettes were made with 40 g of sawdust, at 50 °C, 20 kPa and pressing for 5 min. The results obtained varied as follows: moisture content (4.1% to 7.2%), density (813.9 to 1,014.4 kg/m3), volumetric expansion (7.4% to 37.3%), compressive strength (4.9 to 40.8 N/mm), impact resistance index (46.7% to 200%), ash (0.1% to 1.1%), volatile matter (82.9% to 90.7%), fixed carbon (8.9% to 16.4%), and calorific value (20.5 to 22.8 MJ/kg). The density of the briquettes was within the “acceptable” classification (800 to 1,200 kg/m3). It was observed that, the higher the density, the lower the volumetric expansion, the higher the compressive strength, and the higher the impact resistance index. According to the ash content, the briquettes could achieve international quality. Due to high volatile matter values, rapid combustion of the briquettes with little generation of toxic smoke would be expected. Fixed carbon and calorific value results were acceptable.

ABSTRACTThe purpose of this research is to produce briquettes as an alternative fuel for tobacco ovens. There are two briquettes produced, namely briquettes made from water hyacinth and briquettes made from rice husk ash. The two briquettes were made with a variation of the composition of 10% tapioca starch adhesive and 90% base material to get the best briquette results to be applied as an alternative material in the community tobacco oven process. In addition to variations in the basic material, variations in pellet geometry were also carried out, which included solid boxes, hollow boxes, solid tubes, and hollow tubes. Each geometry is printed with a pressure variation of 10 PSI, 20 PSI, and 30 PSI. The results showed that briquettes made from rice husk ash produced higher heat than water hyacinth briquettes. Hollow briquette pellet geometry produces higher heat compared to solid briquettes. Hollow box geometry produces the best heat compared to solid tube geometry. The optimum pressure in the manufacture of briquette pellets is produced at a pressure of 20 PSI. Keywords: briquettes; water hyacinth; rice husk ash; tobacco oven.

Energy use in rural areas in Nigeria is largely dependent on firewood and other biomass sources. Biomass fuel is domestically used daily for cooking and lighting. Continuous use of this energy resource has negative impact on both the environment and human health, especially on users. Many pulmonary problems have been associated with continuous exposure to smoke arising from burning of these materials. The use of briquetting is a more sustainable alternative to raw burning of biomass as briquettes burn with little or no smoke. However, there is scarcity of data on the emission profiles of major gaseous pollutants arising from many biomass briquettes. This study therefore, investigated the emission profiles of carbon monoxide (CO), carbon dioxide (CO2), sulphur dioxide (SO2) nitrogen dioxide (NO2) and particulate matter (PM2.5) from the combustion of unmodified as well as starch and paper modified briquettes made from four commonly used agro-based wastes namely, wood (control), sawdust (SD), rice husk (RH), coconut shell (CS) and corncob (CC). The gaseous pollutants emitted from combusting 0.5kg of each briquette were measured using appropriate devices. The mean concentrations (ppm) of gaseous emissions and particulates from all briquettes ranged as follows: CO: 35.4 - 79.0, CO2: 500 - 852, NO2: 0.09-0.50 and SO2: bdl - 2.13. All briquettes indicated higher PM2.5 concentrations than control (5190 μg/m3) except SD-paper modified briquettes (3305 μg/m3). CC-paper modified briquettes and RH-starch modified briquettes showed highest concentrations of 21003μg/m3 and 16362μg/m3, respectively. CS-paper modified briquettes emitted the least concentration of PM2.5. This suggests it could be considered as the safest and most ecofriendly of the briquette types.

Recently, the global population has increased sharply, unfortunately, the availability of fossil fuel resources has significantly decreased. This phenomenon has become an attractive issue for many researchers in the world so that various studies in the context of finding renewable energy are developing continuously. Relating to this challenge, this research has been part of scientific work in the context of preparing an energy briquette employing palm oil stems and glycerol crude of biodiesel byproducts as inexpensive and green materials easily found in the Riau province, Indonesia. Technically, the palm oil stems are used for the production of charcoal particles and the glycerol crude as an adhesive compound in the production of energy briquettes. The heating value of palm oil stem is 17,180 kJ/kg, which can be increased to an even higher value through a carbonization process followed by a densification process so that it can be used as a potential matrix to produce energy briquettes. In detail, this study was designed to find out several parameters including the effect of sieve sizes consisting of 60, 80, and 100 mesh, respectively, which are used for the preparation of charcoal particles as the main matrix for the manufacture of the briquettes; the effect of charcoal-adhesive ratios (wt) of 60:40, 70:30, and 80:20; and the effect of varied pressures of 100, 110, and 120 kg/cm2 on the briquette quality. The quality of the obtained briquettes is analyzed through the observation of important properties which involve the heating value and the compressive strength using Response Surface Methodology (RSM). The results showed that the produced briquettes had an optimum heating value of 30,670 kJ/kg, while their loaded charcoal particles resulted from the mesh sieve of 80, in which there was a charcoal loading of 53 g and it pressed at 93.1821 bar, whereas, the compressive strength value of the briquette was 100,608 kg/cm2, which loaded charcoal particles from the mesh sieve of 100, the charcoal-adhesive ratio of 53:47 (wt) and the pressure of 93.1821 bar.

Full textAbstract:
The idea of utilizing biomass as renewable energy source is appealing due to its accessibility, cheapness and ecological friendliness. Briquette is an alternative source of fuel to firewood and charcoal which can avoid some environmental problems that can be generated from their use. Briquettes were produced from watermelon peels with cassava starch and gum Arabic as binders, the two binders were chosen because they are naturally abundant in rural communities. The briquettes produced have favourable thermal and ignition propagation properties which are contributed by the initial raw material (watermelon peels) properties such as density, calorific value, resistance to humidity, moisture content, ash content etc. It can be concluded that the higher the ignition propagation the higher the thermal energy of the briquettes.

Concerns over the past few decades have focused, more than ever, on finding and implementing efficient, handy, and renewable sources to reduce pollution. Biomass, in general, and biomass from annual vine cuttings, are renewable sources that can be used by a large amount of the population. Biomass densification in the form of briquettes is an efficient method of obtaining a biofuel with the same characteristics as wood. The production of densified material as a briquette consists of sampling, drying naturally, chopping, grinding and briquetting the vine cuttings. The obtained results showed that the size of the briquettes met the requirements imposed by the standard, with a length between 185 mm and 400 mm and a diameter of 58 ± 0.75 mm, the humidity of the briquettes varying between 5.42%, at Sauvignon Blanc and 7.98% for Pinot Noir, while the durability of the briquettes registered minimum values of 98.17% for Muscat Ottonel and a maximum of 99.14% for Feteasca Neagra, and a unit density with values between 1227 kg/m3 for Feteasca Alba and 1389 kg/m3 for Pinot Noir. The conclusions of these experiments are promising, showing that the densification of biomass from vines cuttings qualifies within the standard requirements for obtaining a valuable biofuel.

The increasing population and industry in the world have increased the energy demand. Fossil fuel still dominates the current energy consumption in Indonesia, although renewable energy sources are widely available in the country. One of the sources that can be used as a renewable energy source is solid waste as biomass from palm oil processing. The biomass can be converted to solid fuel by using the pyrolysis technique prior molded into a briquette. This study aims to analyze the biomass briquette molding machine in the simulation environment. The solid work simulation is used to analyze the machine regarding the material strength, static test, displacement, strain, and safety factor. The strength test of von mises stresses achieves a maximum value of 3.713 x 105 psi with node 43,485. It is known that the frame is still safe to use because the Yield Strange value is below the Von miss Stress value. Meanwhile, with a maximum displacement of 0.748 cm at node 62,816, a maximum strain of 0.00104 at element 43,485, and a safety factor of 3.278 x 108, it shows this briquette’s design molding machine is safe to use.
