Coal Pulverizer Inlets and Outlets. Louvres (nozzle ring) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base. Some of the pulverized coal is transported from the base of the mill up to the classifier by the hot gas stream i.e. the coal .

pulverizer power consumption (results vary with different operating conditions and coal types). For boilers which have five or more operating pulverizers, the increased capacity could result in reaching full load boiler capacity with one pulverizer utilized as a spare. These new wide-profile roll wheel tires are compatible with existing B&W

coal pulverizer or mill systems. The studies showed that there is an emergence of low rank, high reactive coals as a base fuel for power plants which is resulting in an increase in pulverizer system fires. Also, the EPRI study concluded that reducing the frequency of fires would reduce the risk of coal dust explosions. Unfor-

The shutoff gate is opened when coal pulverizer starts running and closed quickly during pulverizer shutdown or accidents to prevent the flue gas in the furnace returning to the pulverizers and to prevent cold air entering the furnace via pulverizers. For enhanced protection, an electric shutoff gate is installed at the burner inlet.

tration of coal in air below which an explosion does not occur), but do not have an upper explosive limit as long as the coal/ air mixture can be considered a cloud. In practice, a fire occurring during normal pulverizer operation does not result in an explosion. The rich coal.

Depending on the required coal fineness, there are two types of classifier that may be selected for a vertical roller mill. The dynamic classifier, which consists of a stationary angled inlet vane assembly surrounding a rotating vane assembly or cage, is capable of producing micrometer-fine pulverized coal with a narrow particle size distribution.
