제목 | Steam Gasification Characteristics of Biomass in a Fluidized Bed Reactor |
초록 | Biomass is known as an important renewable alternative energy resource. Sawdust was chosen as a resource of biomass, which is suitable for domestic power plants application. To investigate the biomass gasification characteristics and to produce the low calorific value gas in a small pilot scale fluidized bed gasifier (0.1 m I.D x 1.6 m high) at atmospheric pressure, sawdust has been gasified with air and steam. The effects of gas velocity (2-5 Umf), reaction temperature (750-900℃) and the gasification agents ratio of O2/H2O (0.15-1.0) on gas composition, gas yield, cold gas efficiency, calorific value of the product gas and carbon conversion of sawdust have been determined. Carbon conversion (16-35%), gas yield (0.62-0.87 m3/kg-biomass), calorific value (2.6-5.0 MJ/m3) and cold gas efficiency (8.2-22.0%) of the product gas increase with increasing gas velocity and the reaction temperature. With increasing O2/H2O ratio, carbon conversion (13.7-29.2%), gas yield (0.4-1.1 m3/kg-biomass) and cold gas efficiency (9.3-14.2%) of the product gas increase but calorific value (5.2-2.6 MJ/m3) of the product gas decreases due to the decreases of the combustible gas contents. |
