A Review on Co-Gasification of Biomass and Coal

Abstract

Abstract-Gasification is an indirect combustion process of converting solid fuels into combustible gas. Various types of gasifiers have been developed based on the requirements such as fuel flexibility, tar percent of out-coming gas, maximum temperature in reactor etc. Biomass gasification is a much understood technology at its present level. Adding the coal to biomass helps in usage of coal in more environmental friendly and clean way. Present work reviews on co-gasification of biomass and coal in fixed and fluidised bed gasifiers in order to study synergy between both biomass and coal. This work also sheds some light on the single particle experimental work conducted on biomass and coal. It has been found that the increase in the coal percent in the fuel blend on weight basis led to the decrease in the synergy of the co-gasification of biomass and coal because of ash fusion problem.
