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 ...

Coal Mill Lube Oil | Boiler Journal. Nov 10, 2011· Coal Mill lube oil serves as the equipment used for lubrication on gears, thrust bearings, and coupling to the motor bearings in a gearbox. Aside from being a lubricant, oil also serves as a cooling and cleaning of dirt that have negative consequences on the machine.

A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.

To summarize the coal mill controls, they may be divided basically into two major categories: 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF.

Coal mill employed at coal fired power plant. In coal fired energy plant, coal mill is employed to grind, pulverize and dry coal ahead of the coal is transmitted the boiler. The coal is feed into the coal mill by way of a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.

In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro- blems in boiler operation or performance. See Figure 1 for typical heating values of various coals found in the United States.

Effects of Mill Performance on Unburnt Carbon in Coal. Two separate mills referred to as Mill 20 and Mill 40 in this paper supply pulverized coal to the four PC pipes and burners for each elevation The four PC pipes are located at the four corners of the boiler and are referred to as corners 10 20 30 and 40 in this study ref Fig 3.

Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler. Coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, etc.Two major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.

Low grade coal accounts for half of all coal resources in the world, and super-high-moisture coal with a moisture content exceeding 50% is one such kind. When such super-high-moisture coal is applied to conventional USC boilers, the shortage of mill drying capacity and the decline of
