摘要:

二次再热技术以其较高的经济性正得到越来越广泛的应用,我国目前尚无二次再热机组工程投产的实例,相关启动运行经验较为缺乏。以国内第1台660MW等级超超临界二次再热锅炉为研究对象,介绍了机组锅炉的主要特点,并从冷态通风试验、新型吹管工艺、低负荷稳燃、燃烧初调整等方面阐述了二次再热锅炉关键调试技术。针对机组试运行期间出现的燃烧器、风机、控制逻辑等问题给出了解决办法。经过调整优化,机组运行稳定、性能可靠,各项参数均达到了投产要求。

Abstract:

Secondary reheat technology was widely applied due to high economic efficiency. This is not any application of secondary reheat unit in our country yet. Base one the first 660MWclass ultrasupercritical secondary reheat boiler, the unit boiler features were introduced. Key technologies of secondary reheat boiler were discussed from cold state ventilation test, low load stable combustion, preliminary burning adjustment and other aspects. Solutions for the problems of combustor, fan and control logic were provided. After commissioning and improvement, unit operation is stable and reliable. All parameters meet the generation requirements.
