循环流化床锅炉返料口及风水联合冷渣器冷渣风的改造
摘要
神东发电有限责任公司480 t/h循环流化床锅炉存在风帽和水冷壁磨损严重问题。研究发现
导致风帽磨损严重的主要原因是返料口设计不合理。因此
对返料口及风水联合冷渣器冷渣风进行了改造
并用一次冷风代替原冷渣风。改造后
风帽未再发生磨损以及过烧现象
运行情况良好
节能显著。
Abstract
The problem of serious wornout exisits on air-cap and water-wall of 480 t/h CFB boilers in Baode Shendong Power Generation Co Ltd.It has been discovered from study that the main cause leading to serious wornout is the unreasonable design of material-returning entrance
hence
the said entrance has been retrofitted.After retrofitting
the wornout and over-burnt phenomena haven't occurred again.In addition
the retrofit of slag-cooling air for the combined slag-cooler with air and water has been also carried out
using the primary air to replace the original slag-cooling air
