工业锅炉燃烧系统的控制方法探讨

Study of the Control Method for Boiler Combustion System

大量延时空载、煤种多变、蒸汽负荷频繁变化是链条锅炉难以进行良好燃烧控制的原因。本文简要综述了燃煤工业锅炉（主要是链条炉）燃烧控制系统的任务和结构，研究、比较了各种实用控制方法，指出了这些方法的不足之处，为今后燃煤工业锅炉自动控制系统如何改进和发展提出了建议。

It is difficult to have good performances for chain boiler combustion control system due to much no-load time and variation of coals quality and steam load.Firstly this paper simply summarizes the task and construction of the boiler combustion control system.Secondly various control methods of boiler combustion system are investigated and compared,and the shortcomings are pointed out in the methods.Finally,a suggestion is made for the improvement and developement of boiler combustion control systems in future.
