摘要

针对云浮电厂 2号炉 ( 4 2 0t/h)主、再热蒸汽温度偏低、燃烧不稳、结焦严重、自动投入率低等问题

通过分析查找原因

提出了合理布置卫燃带、改造燃烧器和点火油枪、给粉机改变频调速等治理方案。方案实施后

2号炉各项指标均达到或接近设计要求

为解决燃用劣质无烟煤锅炉普遍存在的问题提供了一个成功改造的实例。

Abstract

In view of the troublesome problems

such as lower temperature of main and reheat steam

unstable combustion

serious slagging and low ratio of putting automatic controls into operation

encountered on boiler No2 at Yunfu Power Plant

causes are found through analysis

and a scheme of improvement

including reasonable arrangement of Bailey wall

retrofit of burners and ignition oil-guns

speed regulation of pulverized-coal feeder by frequency-coverting technology etc. are put forward. After implementation of said scheme

indices of boiler No2 have reached or closed to the requirements of design

providing a practical example of successfully retrofitting the poor-grade stone-coal fired boilers to solve the commonly existing troublesome problems.
