某单位于2003年安装了1台150t/h 循环流化床锅炉。在锅炉的实际运行中,由于操作人员对循环流化床锅炉的燃烧规律和各部件的工作原理没能真正理解和掌握,缺乏分析处理问题能力等诸多客观因素的存在,导致了锅炉干锅停炉和尾部烟道燃烧事故的发生。1 基本情况介绍1)循环流化床锅炉系统汽水系统:供水厂(40℃)的脱盐水一除氧器(104℃)→省煤器(320℃)→汽包(330℃饱和水)→下降管→下集箱→水冷壁(饱和水、汽)→上集箱→汽包
A unit installed a 150t / h circulating fluidized bed boiler in 2003. The actual operation of the boiler, due to the operator of the circulating fluidized bed boiler combustion rules and the working principle of each component can not really understand and grasp the lack of ability to analyze and deal with the problem of many objective factors, resulting in boiler dry boiler stop Occurrence of furnace and tail flue combustion incidents. 1 Basic information 1) Circulating fluidized bed boiler system Fouling system: Desalinated water-deaerator (104 ℃) → economizer (320 ℃) → drum (330 ℃ saturated water) → water heater Down tube → lower header → water wall (saturated water, steam) → upper header → drum
