Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers Pulverised fuel quality is critical in achieving clean and efficient combustion. Fuel quality is determined by the properties of the coal and by the design and operating specifications Coal pulverisers performance and safety, IEACR/79 ICSC
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 Maximum coal capacity: 37 [ton h − 1] Coal pulverization rate less than 1000 μm97–98 [%] Coal pulverization rate less than 90 μm50 [%] Coal gas temperature Numerical and experimental analysis of pulverized coal mill
Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals The numeric specification on EL pulverizers indicates the pitch circle of the balls in inches. EL pulverizers operate at capacities between 1½ (EL-17) to 20 (EL-76) tons per hour based on 50 H.G.I. coal. Most electric utility installations utilize the EL-50, EL-64, EL-70 or EL-76. The Babcock and Wilcox EL pulverizers canOptimum Operation and Maintenance of EL Pulverizers
capacity of the pulveriser in tons per hour and an increase in the power required per ton of pulverised coal. The fineness is adjusted by moving the deflector handle(s) on the separator top. When the handle point is set on “O”, the deflector vanes are at their maximum opening, producing minimum fineness.Product: Pall Duplex Assembly. Power generation industry studies have shown that pulverized coal power plants are an area where improved equipment reliability is essential.

The coal is then transported to second crusher and the coal size is reduced to 80 mm Now the coal is feed to the 3rd crusher and the coal is 20 mm size. After this process the coal is the coal is then transported to the pulveriser and then the coal is pulverised.Energy Audit of Coal Handling Power Plant
reduce the size of the incoming raw coal to a fineness that will efficiently burn in a furnace [1]. Fig 1. H P Pulveriser actual view and parts As in fig.2 the raw coal (normally 25 mm) is fed into a rotating bowl through a centre feed pipe Fig.2. HP Pulveriser Coal & Air Flow The rate of coal feed is normally determined automatically1. Introduction. Coal-fired power plants generated 62% of China’s electricity in 2019 (China Electricity Council, 2020), emitting over 3000 megatonnes of CO 2, which contributed to a continuous rise in the global temperature (Li et al., 2020).According to the BP Statistical Review of World Energy report of 2019 (BP, 2019), China contains Prospect of near-zero-emission IGCC power plants to decarbonize coal

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.More O&M News. Pulverizer throughput is determined by the coal fineness desired for a given coal. However, compromising on coal fineness when your pulverizer isn’t up to snuff can increase NO x"Blueprint" Your Pulverizer for Improved Performance
1.1 This test method covers the determination of the fineness by sieve analysis of coal sampled from a dry pulverizing operation. It is not applicable to products of wet milling or to fines that have clustered into an agglomerated mass. 1.2 The values stated in SI units are to be regarded as standard.
