Abstract

Agricultural and forestry waste, domestic waste and sludge are the main energy-containing solid waste resources in rural areas and small towns. In order to use these wastes efficiently, this paper proposes a method based on the co-gasification of biomass, garbage, and sludge in a dual circulating fluidized bed with a combined cooling, heating and power generation method. Based on the principle of thermochemical equilibrium, a system model was established to analyze the performance and the effects of key parameters. It can be found that the power generation efficiency of the system first increased and then decreased with the rise of the pressure ratio of the dual fluidized bed reactor, and the efficiency could reach the maximum value when the steam/fuel ratio in the gasification process was 1.0. The effect of gasification temperature on cooling and heating efficiency is different from that of power generation. As the gasification temperature increases, the power generation efficiency gradually decreases, but the total efficiency of heating and cooling gradually increases. The research in this paper provides a feasible pathway for the treatment of solid wastes such as biomass, garbage and sludge in small towns and nearby rural areas.
