燃料系統培訓原煤倉的配煤主要是通過電動犁煤器來完成。每個原煤斗配置2臺犁式卸料器。每個原煤斗裝有料位計。配煤控制功能分為程控自動配煤、程控手動配煤和就地手動配煤，其中前兩者在PLC的控制下進行，后者無需PLC的參與。輔助車間最終將采用全廠輔助車間集中監控方式，即將水控制網、灰控制網、輸煤程控控制網合并為一個輔控網。Coalblendingofcoalbunkerlayerismainlyfinishedbyelectriccoalplow.Eachprimecoalhopperisequippedwith2plowunloaders.Eachprimecoalhopperisinstalledwithlevelgage.Thecoalblendingcontrolfunctionscanbeclassifiedintoprogrammableautomaticcoalblending,programmablemanualcoalblendingandlocalmanualcoalblending,ofwhich,theformertwoareconductedundercontrolofPLC,whilethelatteroperateswithoutparticipationofPLC.
