摘要

介绍四川内江高坝发电厂 4 10t/h引进循环流化床锅炉投运 4年来出现的主要问题及对流化风管、冷却水、冷却水箱、二次风机、一次风机、旋风分离器回料腿非金属膨胀节、飞灰再循环系统、上二次风口、底灰冷却器等进行的改进情况。这些改进与完善

对循环流化床锅炉的设计、运行有一定的实际参考价值。

Abstract

The troublesome problems occurred in four years from putting an imported title boiler into operation are presented

and retrofit of its components

such as fluidizing air pipes

cooling water pipes

cooling water tank

secondary air fan

primary air fan

non-metallic expansion joints on feed-back leg of cyclonic-separater

fly ash recirculating system

upper opening of secondary air

bottom ash cooler etc.

is described. It is considered to have definite value for reference in design and operation of CFB boilers.
