Penggunaan kompor berbahan bakar padat berupa briket arang biomassa untuk keperluan memasak kurang popular. Ini disebabkan karena ketersediaan bahan bakar tersebut yang belum banyak, dan kompor briket yang menarik belum tersedia. Perancangan kompor ini dibuat dari seng bekas, dengan lubang udara di sekitar ruang bakar kompor, untuk mengetahui pengaruh lubang udara terhadap kinerja kompor. Metode penelitian yang digunakan metode pendidihan air (Water Boiling Test) dan metode perebusan makanan (Controlled Cooking Test), dengan membedakan bahan bakar yang dipakai, yaitu briket dan arang kayu. Hasil uji kinerja kompor yang optimal yaitu pada kompor dengan lubang udara. Waktu mendidihkan air paling cepat didapat pada penggunaan bahan bakar arang kayu di percobaan kedua dengan waktu yang dibutuhkan 9,44 menit, briket yang dihabiskan sebesar 125 gram, laju pembakarannya sebesar 13,24 gram/menit. Sedangkan waktu paling cepat dicapai pada pengujian perebusan makanan pada penggunaan bahan bakar arang kayu di percobaan ketiga dengan waktu yang dibutuhkan 24,17 menit, bahan bakar yang terpakai sebesar 140 gram dan laju pembakarannya 5,79 gram/menit. Meskipun penggunaan bahan bakar arang kayu lebih cepat dalam proses pengujian. Tetapi bahan bakar yang dihabiskan lebih banyak ketimbang penggunaan bahan bakar briket.Kata Kunci : Briket arang biomassa, Controlled Cooking Test, Kompor Briket, Water Boiling Test

In Burkina Faso, finding wood for cooking is still a headache for rural households due to the advancing desert. Here, we try to bring a new way for farmers who already have a biodigester and convince those who are reluctant to adopt this work to reduce their dependence on wood. For this purpose, a characterization of the energy performance of biogas stoves is carried out based on the three-phase water heating test protocol called Water Boiling Test (WBT). The fuel used in the study is the biogas produced by a batch biodigester fed with pig manure. The analysis of the produced biogas shows a methane content of 60% and maximum hydrogen sulfide of 400ppm. The heat balance shows a loss of 11% in the walls of the cookstove and about 36% in the flue gas. Thus the energy performance of the furnace is estimated at 53%, a combustion rate of 6.4 L /min and the average boiling time is 50 minutes. Given these results, we suggest that households use biogas fuel and the B1-3.5mm burner in the cookstove as a replacement for the other burners. We intend to carry out a controlled cooking test on this stove, a modeling of the biogas production and its consumption in this type of burner.

A Value

Fuel is something that is very important in everyday life. Almost every human being needs fuel to meet their needs and support their activities, for example cooking in household needs. Currently, fossil fuels or fuel oil (BBM) are still widely used to meet demand, however, it should be noted that fossil fuels or fuel oil (BBM) are non-renewable natural resources. The biomass rocket stove is one of the modern stove innovations that uses biomass energy as the main energy source. Rocket stoves are designed to increase fuel efficiency with thermal efficiency, a combination of the increased combustion efficiency and heat transfer associated with burning briquette fuel. The purpose of this research is to design and manufacture rocket stove fired with coconut and bamboo biomass for household needs as well as developing methods and equipment for performance testing of rocket stoves. In this study, several steps were carried out, including designing a rocket furnace, selecting biomass fuel and testing the performance of a rocket furnace. From the design of the biomass stove, it is noteworthy that the design with two holes makes the combustion air easily enters and makes combustion in the furnace more perfect and efficient. Water boiling test using three types of solid fuels with the cold start condition suggested that the highest thermal efficiency was coconut fronds with a value of 38% and the lowest thermal efficiency was found from coconut shell combustion, i.e. 22%. During hot start test, the highest thermal efficiency was obtained from coconut fronds firing with a value of 41%. Moreover, with simmer water boiling test method, firing the rocket stove with coconut fronds showed the highest thermal efficiency with a value of 37%.

Low Efficiency

The inefficient indoor burning of fuelwood on traditional cookstoves generates pollutants, primarily carbon monoxide and many other human health-damaging emissions. It is from this risk that it is necessary to have an immediate shift to alternative cleaner fuel sources. Biogas, which is among the biofuels from biomass, is one of the resources that play a considerable part in a more diverse and sustainable global energy mix. For domestic purposes in rural areas of Tanzania, biogas provides a better option that can supplement the use of fossil fuels such as wood, charcoal, and kerosene, which is nonrenewable. However, the low efficiency experienced in the locally made biogas burners hinders the large-scale use of biogas among the population in the country. With the locally made burners, the users of biogas for the domestic application face problems including heat loss and high gas consumption which affects the whole cooking process. It is against this backdrop that the current study objectives incline on designing and improving the efficiency of the locally manufactured burners to achieve the uniform flow of fuel in the mixing chamber, which will result to the consistent heat distribution around the cooking pot. The optimization of the burner was done by using computational fluid dynamics (CFD) through varying the number of flame portholes and air holes as well as the size of the jet before fabrication. The increased efficiency of the burner has also contributed by the addition of the fuel distributor. The results showed that the optimum hole diameter of the jet was 2.5 mm and that of the manifold was 100 mm. The currently developed biogas burner was tested and compared with the other two locally made burners. The water boiling test (WBT) on these three burners showed that the developed burner has a thermal efficiency of 67.01% against 54.61% and 58.82% of the Centre for Agricultural Mechanization and Rural Technology (CARMATEC) and Simgas, respectively. Additionally, the fuel consumption of the developed burner was 736 g/L as compared to 920 g/L for CARMARTEC and 833 g/L for that of Simgas. The developed burner and its corresponding cookstove are both environmentally friendly and economical for household utilization in Tanzania and other developing countries.

Influence of stove dimensions and biomass moisture content on forced draft gasification stove performanceConsumption level of biomass as a source of primary energy in Indonesia is quite high, reaching 280 million barrels of oil equivalent (BOE) and approximately 84% of the biomass is has been used for the household sector. The application of gasification stove especially in cooking purposes can increase the efficiency of fuel usage. This research uses three units gasification stove with variation of stove dimension. Acacia wood branches with moisture content 7.26%, 9.63% and 12.58% were used as fuel source. Water boiling test (WBT) procedural was used to evaluate the stove performance. Operating time and flame temperature of the stove also were the parameter of stove performance evaluation. Thermal efficiency of the forced draft gasification stove is approximately 25.03% to 30.44%, the most efficient is 12 cm in diameter and 16 cm high stove with 9.63% biomass moisture content. Although the resulting flame is still reddish yellow, the forced draft gasification stove is capable of producing up to 3.43 kWth (kilowatt thermal) thermal energy with the highest flame temperature reaches 933oC. The results show that the gasification stove operating conditions greatly affect the performance of the stove.Keywords: biomass, gasification stove, forced draft, thermal efficiency AbstrakTingkat penggunaan biomassa sebagai sumber energi primer di Indonesia cukup tinggi yaitu mencapai 280 juta setara barel minyak (SBM) dan sekitar 84% dari biomassa tersebut digunakan untuk kebutuhan sektor rumah tangga.
