摘　　要：随着农村经济快速发展和农民生活水平提高,基于生物质能源的农村供热越来越受到人们重视。文章采用技术经济分析法,对天津市城郊的小塔沽村生物质气化集中供热和分户供热两种方案进行了对比分析,考察了供热设备、折旧年限、运行费用等因素对经济效益及投资回收期的影响,给出了天津市小塔沽村的供热优化方案,并为农村类似情况的生物质供热提供技术经济参考。With the rapid development of rural economy, residential heating particularly using biomass as feedstock is being paid more attention in rural areas.This paper presents the method of technical and economic analysis of rural residential heating, referring to biomass gasification used for central heating and household heating based on the small Tagu village located in Tianjin suburb. Comparative analysis of economic benefit and investment recovery period by investigating heating equipment,depreciable life,operating costs and other factors was made. The optimization heating mode for the referred Tagu village was finally proposed. The results provide technical and economic references for similar cases in rural areas of China.
