The inefficient indoor burning of fuelwood on traditional cookstoves generates pollutants, primarily carbon monoxide and many\nother human health-damaging emissions. It is from this risk that it is necessary to have an immediate shift to alternative cleaner fuel\nsources. Biogas, which is among the biofuels from biomass, is one of the resources that play a considerable part in a more diverse\nand sustainable global energy mix. For domestic purposes in rural areas of Tanzania, biogas provides a better option that can\nsupplement the use of fossil fuels such as wood, charcoal, and kerosene, which is nonrenewable. However, the low efficiency\nexperienced in the locally made biogas burners hinders the large-scale use of biogas among the population in the country. With\nthe locally made burners, the users of biogas for the domestic application face problems including heat loss and high gas\nconsumption which affects the whole cooking process. It is against this backdrop that the current study objectives incline on\ndesigning and improving the efficiency of the locally manufactured burners to achieve the uniform flow of fuel in the mixing\nchamber, which will result to the consistent heat distribution around the cooking pot.
