ABSTRACT
In Figure 1, pressure control task is to maintain the stability of main steam pressure, the main controller WPI1 according the change of the main steam pressure PM, to load instructions issued to each subsystem of LD combustion rate
1 INTRODUCTION
In the operation of thermal power plant boiler, steam load is often changes, the amount of fuel that must be timely adjust the supply boiler load change, to adapt to the need of load. Automatic regulation mainly includes the automatic feed water regulator, steam temperature automatic regulation and automatic adjustment of boiler combustion process. The combustion process of automatic regulation requires not only the heat provided by burning fuels adapt to the need of load, but also ensures economical combustion and safety operation.
