Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
Coal Pulverizer is the one of the critical power plant component that is relied upon convert the energy stored in coal into electricity. The Classifier located on the top of a mill returns the over size material back to the pulverizer but allows the proper sized material to pass out of the mill to the burners.
Coal is supplied to the boiler furnace by eight Babcock & Wilcox 10E10 ring and ball type mills and associated drag link feeders, each capable of a coal output of nominally 38 tonne/h. The coal mills are fitted with rotating port throats and non-adjustable static classifiers.
-However, the load dynamics of a coal-fired power plant unit are naturally restricted by the sluggish response of the steam generator, with its huge iron mass and the large boiler drum and pipe volumes where steam is stored. Several minutes will pass between a step increase in fuel flow to the coal mills and the steam generator's response.

The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [ [11], [12], [13] ].
FIGURE 7-2. Coal production and consumption in the U.S. in the past 150 years. [Source: Energy Information Administration.] Coal Formation As described in the general discussion of the carbon cycle (Chapter 6), coal was formed from prehistoric plants, in marshy environments, some tens or hundreds of millions of years ago.

The flow of coal particles through a classifier is several times the amount of coal flowing to the burners because of the large amount of coal recirculated within a pulverizer. For example, if a pulverizer is operating at 100,000 lb/hr coal feed to the burners, as much as 300,000 lb/hr or more may be flowing through the classifier for regrinding.
