boiler is a important power equipment,the require is to provide qualified vapour,let the amount of vapour maked by boiler suit for the load.because of this,every main parameter in the process of the product should be strict controlled.this paper is introduced same main control system in the process of boiler control、concentrate and disperse control system 、the characteristic and the develop of the MCGS compose status software.integrate with the technique of the boiler, discuss the single momentum, double momentum, three momentum boiler control system distinguishly.we think in the process of micro boiler control, three momentum control is the best choice,and has been well implemented in the water level mediation.further more,use the concentrate and disperse control and MCGS compose statue sofeware can achieve the control of the boiler,and can reach a fine effect..

锅炉是一个重要的动力设备，其要求是供给合格的蒸汽，使锅炉发气量适合负荷的需要。为此，生产过程的各个主要参数必须严格控制。本设计了研究锅炉控制过程的几个主要控制系统，以及集散控制系统和MCGS组态软件的特点和发展状况。结合锅炉的工艺情况，针对单冲量、双冲量、三冲量锅炉控制系统，对它们存在的利弊做出了比较和分析。结合生产实践，对三冲量的算法进行比较，认为在小型锅炉控制过程中，三冲量控制是最好的选择，并在水位调节中得到很好的应用。
