first commercial nuclear power plant began operating in 1954 in Shippingport, Pennsylvania. If we mark the oil price shocks of the 1970s as the birth of significant interest in solar energy and other renewable resources, it seems reasonable that massive use of solar energy may begin around 2030. There will be enough coal to carry us through to

COAL BASED THERMAL POWER PLANTS: COAL HANG UP IN BOWL MILLS

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.
