There are many types of mills and bowl mill is one of them, all these mills can face coal hangup. For taking corrective action during a coal hangup in bowl mills the operator will have to know the reason for such a hangup, 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
