Coal Hang-up in Bowl Mill Operations Bright Hub Engineering

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 the boiler back to normal condition as early as possible.
