Abstract :
The firewood, procured from the market has moisture content in the range of 25-30% (wb). While for Gasification, the moisture content of sized wood should be in the range of 12-15 % (wb). The situation becomes worst during rainy reason when the atmospheric humidity is very high, and there is no sunshine. The moisture content of a gasifier feed stock plays a very important role in the quality of producer gas. High moisture feed stock does not burns properly, generate more smoke and tar. The conversion efficiency of Gasification is also low; however, dry biomass provides considerable benefits for thermal conversion of biomass. Excess heat of Producer gas could be utilized for drying of biomass feed stock. Developed gasifier waste heat based feed stock dryer took about 8 to 13 hours to reduce the moisture of biomass up to 12%, depending upon the initial moisture content of the biomass. Size of biomass play important role in drying of biomass. Smaller size biomass took more time than larger size biomass, to reduce the moisture up to desire limit (12-15% wb), even though moisture content of biomass was maintained same.
