coal mill pulverizer in thermal power plants

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal are sent to the boiler

    The four most common types of coal pulverizers are: Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills

    The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates. In extreme cases, the performance of the boiler may …
