摘要

介绍了300 MW机组循环流化床(CFB)锅炉水冷壁爆管的情况。分析认为1号炉左侧冷渣器锥形阀压缩空气吹扫手动门不严

2号炉水冷壁延伸墙鳍片漏焊、未清除临时焊件

以及热风与物料的长期冲刷是爆管的主要原因。对此

提出了相应的处理和预防措施。

Abstract

The situation of tube-burst occurred on the water-wall of 300 MW circulating fluidized bed(CFB) boilers has been presented.It is believed from analysis that the main causes are as follows:(1) untightness of the hand-operated valve for purging the tapered valve of slag-cooler at the right side of boiler no.1 by using compressed air;(2) unwelded fins of extended wall on the water-wall of boiler no.2;(3)the temporary weldments haven't removed;(4) long term scouring by hot air and other materials.For these

corresponding treatment and preventive measures have been put forward.
