Abstract: This paper describes the application of the advanced control technology (APC) in large heating units of storage pulverized coal furnaces in power plants. Through DCS control optimization
and one-key start and stop of each subsystem, the control trouble caused by the change of coal quality and individual process parameter can be avoided. By using the operator's actual operation as the criterion, the whole logic design and program control design can be established. On these two bases, the APC optimization of the main steam pressure, main steam temperature, boiler combustion and denitrification system are carried out. The daily operation intensity of operators can therefore be reduced through multiple means so as to achieve the purpose of black screen operation.
Key words: APC (advanced process control); Advanced control;Intelligent DCS; Black screen Operation; Machine replacement
