From Fig. 5, the inlet primary air flow of coal mill is regulated by the mixed air valve, and the primary air flow instruction is converted from the coal feed flow instruction. At the same time, the feed-forward signal of the coal feed flow instruction is superposed in the mixed air valve control.
Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is fed into the coal mill via an inlet pipe so that the coal mill can pulverize the coal into particles. Materials:Coal, cement clinker, limestone, calcite, dolomite, talc, etc.
In many applications, there is an elbow, scroll or turning head in the coal pipe at the burner inlet. Such inlet devices result in 'roping', or an uneven distribution of coal within the fuel injector. Many manufacturers use components to redistribute the coal particles with an even density around the circumference of the fuel injector at ...
Close the raw coal feeder inlet gate if not already closed; After making sure all the above are closed, open the inspection door of the mill Check if the coal pipe from feeder to mill is clear and make sure they are made clear; Check raw coal feeder and if chocked then get it cleaned; Check the raw coal feeder shear pin and replace if needed
