types of coal in cement plant

Cement Plants: Coal

Bituminous coals make the best coke and are in any case the most common, and these are most often used in the cement industry, although steam coals are occasionally used. When burning a pulverised fuel, higher volatiles are preferred because they speed up ignition and allow a coarser grind to be used.

Coal in the cement industry

Coal fineness has a direct relationship with its reactivity. Hence in the cement plant a special significance has been given to the milling behavior of coal. It has been observed that low volatile matter in coal can be co mpensated by finer grinding. It is also desirable that coal must have a high Hardgrove Grindability Index (HGI)

Peat is the lowest grade of coal with carbon content less than 35%. The cement industry mainly uses non coking bituminous coal and lignite in small quantities in plants in Tamil Nadu and Rajasthan. Specifically, the coal used by the Cement Industry is of grade G4, G5, G6, G7, G8 and G9.

What are the types of coal? - USGS

What are the types of coal? There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.

Cement Plants: Coke

Coal consists of a wide variety of chemical structures, the amount of each depending on its rank. There are fused cyclic structures, mainly aromatic, but some alicyclic, from which branch aliphatic chains of varying lengths. On pyrolysis, the cyclic structures become progressively aromatized by dehydrogenation, and the side chains are cracked off.

Cement Plants: Coke

The normal "green" coke is used as a fuel, where it can be more convenient to use than fuel oil because its properties are sufficiently similar to those of coal that coal/petcoke mixtures can be used in power generation or cement manufacture in whatever proportions desired without major modifications to plant. Petcoke differs from coal most obviously in its almost total lack of ash and its relatively high sulfur
