Abstract: In order to guarantee safety operation of the biomass gasification station in the north of China in winter, a method which makes the waste heat of biomass gasification reaction go into purification room by using axial flow fan and double-tube is proposed. Simulation is performed for heat environment of the heated purification room of the biomass gasification station by computational fluid dynamics (CFD) approach using Fluent. The temperature of purification room can reach to 254K when the situation temperature in Shenyang is 243.15K. The temperature of purification room will continue to enhance to 278K when the heat measures are taken to envelope. And the requirement of freeze prevention is met and the feasibility of double-tube heating is proved. It provides some references for the transformation of freeze prevention of biomass gasification station in northern China.

Key words: biomass gasification, freeze prevention, double-tube, computational fluid dynamics(CFD)
