600MW亚临界压力控制循环锅炉的开发与研究

上海锅炉厂有限公司最新开发的SG -2 0 0 8/ 1 7.5M 90 1型锅炉为亚临界压力、一次中间再热控制循环汽包炉。在总结同类型国产引进型和国外进口锅炉存在问题的基础上作了改进和创新 ,使锅炉性能优良。解决了烟温、汽温偏差偏大 ,再热器超温 ,燃烧器摆动困难和导热器漏风大等问题。运行结果表明 ,该锅炉的各项技术指标可同进口锅炉媲美。

Exploitation and Study of 600MW Sub-Critical Pressure Controlled Circulation Boiler

The newly exploited boiler with the type SG 2008/17.5 M901 is sub critical pressure, once reheat, controlled circulation steam drum boiler. It summarized problems existing on the same type, home made introduced ones and imported ones, made improvements and innovation on design, which makes the boilers have good performance. Gas and steam temperature deviation being fairly high, reheater over temperature, swing diffculty for burners, and air preheater leak high etc have been settied. Each technical index can match the one for imported boilers.
