Influence of Coal-Biomass Fuel Composition on the Efficiency of its Conversion in Entrained-Flow Gasifiers

Abstract

Co-gasification process of coal and plant biomass mixtures in entrained flow of oxygen and steam was investigated using mathematical modelling. The calculated dependences of the process characteristics on the control parameters (such as fuel composition, gasification agent composition and the stoichiometric ratio) are obtained. For the linear dependence of the ash melting temperature on its composition, the regions of parameters in which the process is technologically feasible are highlighted. The effect of temperature limitations on the efficiency of the gasification process is estimated.
