摘要：APC先進控制技術在電廠倉儲式煤粉爐大供熱機組上的應用。通過DCS控制優(yōu)化和各分系統(tǒng)的一鍵啟停，可以避免因為煤質(zhì)變化以及個別工藝參數(shù)無法量化帶來的困擾; 并且以運行人員的實際操作為準繩，去確立整個邏輯設計和程控設計。在此兩個基礎上進行主汽壓力、主汽溫度、鍋爐燃燒以及脫硝系統(tǒng)的APC優(yōu)化，通過多個手段去減緩減輕運行人員的日常操作強度，達到黑屏操作的目的。

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.
