Control for pulverized fuel coal mill - IEEE Conference Publication

Coal fired plants are known to have low load take up rate and sometimes face complete shutdown. This is basically due to the poor dynamic response of the coal mills. This paper focuses on the flow control of pulverized fuel (pf flow) of the coal mill. The control performance given by the conventional PID, Fuzzy-PID and I.

Coal Mill Classifier Repair Case Study | Duromar

The Coal Mill Classifier Cone directs the pulverized coal out of the mill and into the furnace. Hot air, from the air side of the air preheater, is pulled through the coal mill by the exhaust fan (refer CH-801) picking up the fine coal dust and feeding it to the furnace. The classifier cone is generally lined with thick Alumina wear.
