Abstract: The coal-pulveriser/coal-mill is an important subsystem upstream of boilers in coal-based thermal power plants. The efficient boiler operations demand optimum combustion-air to coal-fuel ratio (AFR). In fact, portion of (preheated) combustion-air called primary-air, passes through coal-mill and carries pulverised coal to the boiler.

Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding, and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging.

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 ...

Pulverizers, also called mills, are used by many industries to grind solids to a fine powder. Performance of coal mills at power plants is critical to: Combustion efficiency/heat rate NOx & CO reduction Unit availability/power output. Optimization of the flow patterns of both air and coal entering, within, and exiting a mill is an important part of plant performance.

The Problem - Coal fired power plants typically operate several ball mills or coal pulverizing mills to crush the incoming coal to the optimum size for combustion. This means that each power generation unit has five or six mills. The gearboxes that run these coal mills are usually lubricated with high viscosity oil, such as ISO VG320 or ISO VG460.
