THERMAL POWER PLANTS COAL HANGUP 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.

The firing and co-firing of biomass in large pulverised

 · •  The milling of wood pellets in coal mills and the firing of the mill product through the existing pipework and burners is done at a small number of power stations in Europe including Hasselby in Sweden •  The coal mills are very robust and have high availability and low maintenance requirements •  Hammer mills are more sensitive to tramp material and have a much higher maintenance requirement depending on the fuel quality •  The coal mill depends on a crushing mechanism and tends only to break the pellets back to the original sawdust size distribution •  The mill has to be modified to operate with cold primary air and to maximise the fuel throughput •  There are generally no requirements for modifications to the coal mill
