Composition, biomass husks

Commercial gasifiers are available in a range of sizes and types, and run on a variety of fuels, including wood, charcoal, coconut shells and rice husks. Power output is determined by the economic supply of biomass, which is limited to 80 MW in most regions. The producer gas is affected by various gasification processes from various biomass feedstocks. Table 6.7 shows composition of gaseous products from various biomass fuels by different gasification methods. 

Biomass is recycled into usefiil products in three ways. First, easily decomposable materials such as fruit and vegetable peels are made into composite manure. A second method of recycling biomass is to dry it and heat it in the absence of air to make charcoal. Currently, two companies in Nairobi, namely the Kenya Planters and Co-operative Union (KPCU) and Chardust Ltd., are making charcoal from biomass. KPCU uses coffee husks. 

Rice husks are an important by-product of the rice milling process and are a major waste product of the agricultural industry. They have now become a great source as a raw biomass material for manufacturing of value-added silicon composite...
