Thermodynamic Analysis of Biomass Gasification by Different Agents

Abstract

Biomass gasification was investigated by a thermodynamic analysis with the scope to understand the effect of the injection of different gasifying agents and of the gasification temperature on the output variables of process. The thermodynamic analysis was carried out by a freeware commercial software. Gasification temperature in the range of 750-950°C, together with different gasification agents air and steam, were investigated. In the case of air process equivalence was varied up to complete combustion of the biomass. For steam gasification the molar steam/biomass ratio was increased up to 9. The investigated output variables of the process were gas yield, heating value and gas composition.
