循环流化床锅炉结焦原因分析及预防措施
摘要
分析了循环流化床锅炉结焦的原因
认为其主要因床料局部或整体温度超过灰熔点或烧结温度
以及炉内流化工况不良等所致。对此
提出了改变燃煤焦结特性
严格控制运行参数
尽量缩短压火时间等措施
以避免循环流化床锅炉结焦。
Abstract
The causes resulting in slagging for circulating fluidized bed(CFB) boilers have been presented.It is believed that the causes are mainly as follows: the local or entire temperature of bed material exceeds the fussion point of ash or the sintering temperature;the fluidized condition in furnace isn't good
etc..For these
some measures as improving the slagging property of fuel coal
strictly control the operational parameters
and shortening the time of banking fire as possible
