摘要

分析了 10 2 5t/hUP型直流炉水冷壁管频繁爆漏问题

认为水冷壁热敏感性强、炉内热偏差大、刚性梁及密封结构不合理等锅炉设计及运行操作中存在的诸多问题是造成爆漏的主要原因

对此提出了相应的改造措施

Abstract

The causes of frequent water-wall leakages induced from tube-burst on 1025t/h UP once-through boiler have been analyzed. It is considered that the main causes of said problem are defects existing in boiler design and operation

such as strong thermal sensibility of water-wall tubes

great heat deviation in the furnace

unjustifiable structure of rigid beams and furnace hermetization etc.. Hence

corresponding measures for retrofitting have been put forward.
