The pulverised fuel continues its journey towards the coal burners for combustion. The coarse particles rejected in the classifier are returned to the mill for another cycle of grinding. In order to avoid excess sweeping of coal from the mill only part of the primary air directly proportional to the boiler load demand is passed through the mill.
Coal Inlet coal is fed to the centre of the grinding table. Coal fed to the mill may be raw or pretreated. Pulverized Coal Outlet/Discharge pulverized coal flows out of an outlet duct. How Vertical Grinding Mills Work. The below video is an extract from our Mechanical and Electrical Engineering Explained Online Video Course.
The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace to combustion of the particle is very short. This time, however, is dependent on various factors. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill.
