燃烧器的自动控制直接影响到锅炉机组运行的安全性、可靠性和经济性,特别是对大容量锅炉机组,为防止在点火和低负荷燃烧不稳定时引起的炉膛爆炸、及时控制炉内燃烧工况、改善工人劳动条件、防止人为误操作引起的重大事故,燃烧器必须配备一整套完善的自动控制装置,本文介绍了大容量锅炉燃煤、燃油、燃气燃烧器自动控制的典型实例,提出对300MW和600MW锅炉机组,应积极研制和推广以计算机技术为基础的可编程序控制器或徽处理器,实现可编程控式逻辑系统(FSSS系统),并对炉膛和燃烧器进行安全监控,提高锅炉机组的运行水平。
The automatic control of the burner directly affects the safety, reliability and economy of the operation of the boiler unit, especially for the large-capacity boiler unit. In order to prevent the explosion of the furnace chamber caused by the ignition and the combustion with low load instability and to control the combustion in the furnace in time Conditions, to improve working conditions of workers, to prevent human error caused by a major accident, the burner must be equipped with a complete set of automatic control device, this paper describes the large-capacity boiler coal, fuel, gas burner automatic control typical example proposed For 300MW and 600MW boiler units, a programmable logic controller or emblem processor based on computer technology should be actively developed and implemented to realize a programmable logic control system (FSSS), monitor the hearth and burner safety, Boost the operation of the boiler unit.
