摘要
目前已运行循环流化床(CFB)锅炉,特别是220 t/h以上的CFB锅炉对炉内脱硫系统的运行经验不足,文章针对福建无烟煤的燃烧特性,经过对石灰石脱硫系统的运行调试,探讨CFB锅炉炉内脱硫中涉及的若干问题,分析脱硫影响因素及添加石灰石对锅炉的影响。同时希望石灰石脱硫技术能在同炉型循环流化床电厂中得到更多推广应用,使循环流化床锅炉清洁燃烧的优点得以更好体现。
Operated circulating fluidized bed (CFB)boiler, especially CFB boiler over 220 t/h, the operation experience of desulphurization system is inadequate. According to Fajian anthracite's combustion performance,operation debugging to lime stone desulphrization system, the paper discusses some problems of CFB boiler desulphurization, and analyses desulphurization's influence factor and adding lime stone to boiler's influence. Meanwhile it is expected that lime stone desulphurization technique is widely application in same sype circulating fulidized bed, the advantage of clean combustion for circulating fluidized bed boiler can be realized.
