/生物质循环流化床锅炉热效率性能实验 /

介绍了以农林废弃物为主要燃料的生物质直燃循环流化床锅炉。对生物质循环流化床锅炉进行了额定、常用及最大负荷下的热效率测试实验,并对其热效率进行了修正。结果表明:锅炉热损失主要来自排烟热损失q2和固体未完全燃烧热损失q4;对进风温度、给水温度、燃料特性进行了修正,在12,13.5,15 MW工况下修正后的热锅炉效率分别为87.57%,88.77%和88.72%。 Introduce the biomass direct-fired circulating fluidized bed boiler which takes farming and forestry residues as main fuel.Do heat efficiency test of this kind boiler under rated,ordinary and maximum load.Then correct the heat efficiency data.The results show that heat loss due to exhaust gas q2 and solid fuel imperfect combustion q4 is the main heat loss of boiler.Correct some data such as inlet air temperature,water supply temperature and fuel characteristics.After correction the heat efficiency of boiler is 87.57%,88.77% and 88.72% while the working condition is 12,13.5,15 MW
