ABSTRACT

Synthesis gas can be generated from Biomass through thermo chemical conversion process. In this study rice husk, coir pith and saw dust mixture were selected in 50%-50% by mass and gasification process was carried out for synthesis gas generation in a self circulating fluidized bed Gasifier. Synthesis gas composition was analyzed for various equivalence ratios of 0.3, 0.4 and 0.5 for the period of 10 minute time interval and the effect on gas constituents was studied. Key parameters i.e Gas yield, gas heating value, overall carbon conversion and cold gas efficiency were used to evaluate performance of the gasification system. The result indicate that combustible gas generation are high at lower ER. With increase in ER the gas yield increases and HHV of the gas decreases. Optimum ER is considered to be 0.3 for syngas generation. Keywords: Self circulating FBG, Equivalence ratio, gas yield, dry gas HHV, gas composition, overall carbon conversion, cold gas efficiency
