The paper in the light of the defects of problems existing in the present structure of small biomass gasification furnace , design a small biomass gasification furnace , and takes it as the research object , built up the experimental plat-form , the experimental research .The experiment by changing thegasification agent air flow , analyses the influence of gas-ification agent air flow on the performance of gasifier , and by changing the gas air distribution experiment , the influence of air distribution on flue gas furnace gasifier .The experimental results show that , HEGF-2 typebiomass gasification fur-nace has the advantages of simple structure , low cost , stable operation , sufficient heat exchange , the advantages of gas production quality and high calorific value andenergy saving and environmental protection .%针对目前小型生物质气化炉结构存在的缺陷，设计了一种小型生物质气化炉，并以其为研究对象，自行搭建了实验台，进行了实验研究。实验中，通过改变气化剂空气流量，分析了气化剂空气流量对气化炉性能的影响，并通过改变燃气配风量得到了配风量对气化炉烟气排放的影响。实验结果表明， HEGF-2型生物质气化炉具有结构简单、成本低、运行稳定、换热充分、产气品质和热值高、节能环保等优点。
