一起非典型的流化床锅炉超温事故原因分析及预防措施

Cause Analysis and Preventive Measures of an Atypical over Temperature Accident of a CFB Boiler

循环流化床锅炉(以下简称CFB锅炉)具有排放污染低、燃料适应性广、燃烧效率高及负荷适应性强等优点。但是,CFB锅炉在运行过程中也存在较多问题。本文通过分析一起因引风机动叶调节连杆脱落而引起的屏过超温事故,旨在探讨处理此类事故的正确办法,为生产运行人员提供借鉴。

CFB boiler has the advantages of low emission pollution, wide fuel adaptability, high combustion efficiency and strong load adaptability. However, there are many problems in the operation of CFB boiler. This paper analyzed an over temperature accident of the screen caused by the falling off of the regulating link of the induced draft fan moving blade, aiming to explore the correct way to deal with this kind of accident and provide reference for the production and operation personnel.
