THERMAL POWER PLANTS: COAL HANGUP IN BOWL MILLS. 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.
A thermal power plant converts heat energy to electricity from heat sources such as steam and fossil fuels. Thermal power plants rely on conveyor transfer systems to transport coal and in some cases ash from the unloading point to the designated storage site. Depending on the site of the power plant and load capacity, you may need to employ one or multiple transfer systems.
