摘要
针对2台300 MW锅炉再热汽温低、屏式过热器壁温报警和过热器减温水量大的问题,分析了产生原因,提出了墙式辐射再热器改造方案,并进行了燃烧调整试验,改造后的实际运行数据表明,过热器壁温和减温水量得到改善,提高了再热器汽温。为同类型锅炉技术改造提供可借鉴经验。
Focusing on the low reheat steam temperature, overheating of platen superheater tube wall as well as the overlarge consumption of attemperation water, this paper fistly analyze the root causes, and then propose a reform scheme for the radiation reheater. In addition, combustion adjustment experiment has also been implemented. The field operation data obtained after reform indicate that the reheat steam temperature has increased and the issues associated with superheater tube wall temperature and attemperation water have also been mitigated. This work can provide valuable reference for the reform of similar boilers.
