摘　　要：以广州某公司的气化效率较低的上吸式固定床气化炉为研究对象,利用数值模拟研究方法,对气化炉的结构进行优化改进。分别对单面、双面、三面进风的炉内气流进行研究,探究进风口与水平面的夹角对炉内气流的影响。结果表明:采用双面进风,下倾角为45°时,炉内气流分布状况最佳。结构优化方法为生物质气化炉体改造提供参考。Taking the updraft fixed-bed gasifier with low gasification efficiency in a Guangzhou company as the research object, and using the numerical simulation research method to optimize and improve the structure of the gasifier. The airflow in the furnace of the single-sided, double-sided and three-sided air inlets is studied respectively, and the influence of the down inclination angle on the airflow in the furnace is also considered. The results show that the airflow distribution in the furnace is the best when the double-sided air inlet is adopted and the down inclination angle is 45°. The structural optimization method can provide a certain reference for the transformation of biomass gasification furnace.
