Abstract: Biomass can be converted to gaseous fuels through thermo chemical conversion process. In this study rice husk, coir pith and saw dust were selected and gasified in a self circulating fluidised bed gasifier. Gas composition has been analysed for equivalence ratios of 0.3, 0.4 and 0.5 for 10-minute time intervals and its effect on gas constituents has been studied. The gas yield has been found to be in the range of 1.5-2.4 Nm³/Kg, 1.6-2.9 Nm³/Kg and 2-3.2 Nm³/Kg for rice husk, coir pith and saw dust respectively. The study has been carried out in a pilot model gasifier.

Keywords: self circulating FBG; equivalence ratio; gas yield; reactor temperature; gas composition; pilot model.
