The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.

There are many types of mills and bowl mill is one of them, all these mills can face coal hang-up. For taking corrective action during a coal hang-up in bowl mills the operator will have to know the reason for such a hang-up, how the plant will respond, what he has to respond to and what the local operator will have to do. This will reduce the chance of mill trip and bring back boiler to ...

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.
