摘　　要：以典型30 MW的农林生物质发电机组为研究对象,对比常规方案和再热方案的初投资、发电收益和燃料成本,并且对再热方案在农林生物质发电机组的经济性进行分析。结果表明:与常规方案相比,再热方案初投资增加1956万元;分别从发电收益和燃料成本角度分析,再热方案初投资增加额的静态投资回收年限都在5 a左右,具有明显经济性,可为农林生物质发电机组装机方案和主机型式选择提供参考。Taking a typical 30 MW agroforestry biomass power generation unit as the research object,comparisons were conducted on initial investment,power generation income and fuel cost of conventional scheme and reheat scheme,and the economy of reheat scheme in the biomass power generation unit was analyzed.Results show that compared with conventional scheme,the initial investment with reheat scheme increases 19.56 million yuan.From the point of power generation income and fuel cost,respectively,the static pay off periods of initial investment variations with reheat scheme are both about 5 years,which presents a good economy.This may serves as a reference for installation and heat-engine type selection in agroforestry biomass power generation units.
