440t/hCFB锅炉结焦原因分析与对策
摘要
结合某台440t/h循环流化床(CFB)锅炉运行过程中因结焦而导致停炉的实例
分析了CFB锅炉结焦的特性和影响因素
并提出了预防结焦的措施。对相关参数的分析表明
床料流化不良和高温下颗粒的粘性变化是导致结焦的重要原因。
Abstract
Combining with the fact that the boiler must be shutdown when slagging occurred in a 440 t/h circulating fluidized bed (CFB) boiler in the process of operation
the slagging mechanism in CFB boiler and affecting factors have been analysed
and measures for preventing slagging being put forward. Analysis of related parameters shows that the important causes leading to slagging in CFB boilers are badly fluidized bed material and variation of particles’ adhesiveness under high temperature.
