摘要：In today’s global fuel usage scenario the need for fossil fuel is very high, and is depleting. Thepollutions caused by the fossil fuel are as high as the demand. The threat of energy depletion and greenhouse gas effectprove that fossil fuels are no longer sustainable for wide use. As a result of environmental and policy considerations aswell as dwindling oil resources, there is increasing interest in using renewable energy sources. An alternative energyresources that is sustainable for use, environmental friendly as well as regionally available has been laid a challenge forresearchers. The use of biomass to generate heat power, fuels and chemicals is crucial in achieving energyindependence and increasing our use of renewable energy sources. The availability of bio-residues from variousagricultural activities has been estimated to be around 300 million tons per year in India. A considerable portion of thisquantity is getting wasted. Gasification promises to play a major role in large part because its products can make use ofexisting infrastructure and equipment associated with fossil fuel use. In the present work, a biomass gasifier ofdowndraft type is designed and tested with the feedstock of corn plantation wastes blended with suitable agents toprovide continuous burning. This research investigated gasification and corresponding thermal conversion efficiency ofcorn biomass fuel. As a result, it was found that the thermal conversion efficiency was around 65% with a heatingvalue of fuel to be 4.2MJ/m3. It was observed that the biomass having light weight was better for feeding in thegasification system. Much fewer bridging and clogging issues occurred than pure wood.
