Example: Our dryer needs 1155 BTU per pound of water removed to dry material from 20% ds to 90% ds. If a steam boiler is used the boilers efficiency is typically 80%. Thermal fluid heaters can have thermal efficiencies of 80% to 88% depending on design. Energy recovery should be considered if the plant has hot stack gases.

Mill differential pressure comes down Mill outlet temperature will rise Boiler steam pressure will start falling No coal flow alarm will appear Coal feeder and mill will trip after some time
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.
