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 ...
During mill shut down, the same inerting process starts when the coal feeder is stopped or mill coal inventory reaches a certain level. The inerting process is recommended to continue until the mill is ... primary air inlet duct through a 6" steam pipe. For mill emergency trip, the inerting steam is introduced ...

Aug 29, 2010· Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.
The raw coal enters the feeding device of the mill from the feeder equipment, and the hot air having a temperature of about 300 °C also enters the feeding device through the air inlet pipe. A special lifting plate is arranged in the drying chamber to raise the raw coal so that the raw coal is subjected to intense heat exchange here to be dried.
