· Class-F is produced mainly by burning harder, older anthracite and bituminous coal. Compositionally, this fly ash is pozzolanic in nature, and contains less than 7% lime (CaO). Class-C fly ash is produced from the burning of younger lignite or sub-bituminous coal.
UNIT-1.2 Preparation and Burning of Coal [Repaired]x ...
PULVERIZED FUEL BURNING Coal is pulverized (powdered) to increase its surface exposure there by permitting rapid combustion. Coal is reduced to a fine powder in grinding mill or pulverizes Advantages of pulverization of coal 1. By breaking, a given mass of coal into smaller pieces exposes more coal surface area for combustion. 2.
Improving Coal Pulverizer Performance and Reliability
Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly

Apparatus and method for the pulverization and burning of solid fuels, such as coal, that provides for introducing relatively coarsely divided solid fuel into the lower part of an upstanding, closed housing for impact crushing therein, and for carrying the fuel fines upwardly through a turbulent zone defined in the housing between rotating spiders that include widely spaced radial blades that ...
The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of coal according to the boiler demand and the amount of air available for drying and transporting the pulverized coal fuel is controlled by ...

Coal pulverisation | The Nature Of Science
coal has been reduced to the desired fine powder. Some power stations crush coal into fine dust in pulverising mills. These mills work by repeatedly dropping massive steel balls on to. the coal until it is crushed into fine coal dust. The steel balls used. at Drax, for example, are hollow, about 73 cm in diameter, and weigh.
Geochemical partitioning from pulverized coal to fly ash ...
· Pulverization eliminates <1% of the raw feed coal, but, in reducing the amount of pyrite and hard rock in the feed coal, eliminates more that 10% of the As, Hg, and Se, among other hazardous elements, from the feed to the boiler. Pulverization also levels the variation in the boiler feed, smoothing the natural variation in ash chemistry.
