摘　　要：循环流化床锅炉是一种高效低污染的先进燃烧设备,应用广泛.但由于其具有煤种适用性广和燃烧稳定的特点,广泛用于燃烧劣质煤、石煤和煤矸石,因此,二氧化硫和氟化物排放污染控制问题不容忽视.75 t/h和200 t/h循环流化床燃烧固氟技术应用表明,流化床燃烧燃烧温度十分适合石灰石燃烧固硫固氟的要求,在循环流化床锅炉燃烧时添加石灰石可显著降低锅炉出口烟气中二氧化硫和氟化物的排放浓度及排放量,具有同时脱出二氧化硫和氟化物的作用,具有显著的经济效益、环境效益和社会效益.Circulating fluidized bed combustion boiler is an efficient low-pollution combustion of the art equipment, wide range of applications. However, due to its wide applicability of coal, combustion stability characteristics of the widely used low quality coal combustion, and coal gangue, the fluoride emissions of sulfur dioxide pollution control and can not be ignored. 75 t/h and 200 t/h circulating fluidized bed combustion technology-fluoride： fluidized bed combustion temperature is very suitable for burning limestone burning sulfur-fluoride requirements in the circulating fluidized bed combustion boiler add limestone can significantly reduce the export of boiler smoke emission of sulfur dioxide and fluoride concentrations and emissions at the same time with fluoride and sulfur dioxide away from the limitations of the role, with significant economic, environmental and social benefits.
