[Objective]The study aimed to discuss the factors influencing the application of shaping biomass energy in the NH3 /He absorption refrigeration system. [Method]In the NH3/He absorption refrigeration system,the thermodynamic analysis of semi-gasification furnace based on sectional combustion technology and absorption refrigeration system was performed. [Result] Biomass could burn cleanly and efficiently in the semigasification furnace,which can reduce the environmental pollution caused by the combustion of coal and other fossil fuels. The heating power of the furnace for the absorption refrigeration system could not be too high,so biomass energy and other low-grade energy can be used as heat sources, which opens up a new way for the utilization of biomass energy. [Conclusion]Biomass energy was applied successfully in the absorption refrigeration system.
