London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was ...

Coal Reserve As per the report of Working Group on Coal and Lignite for XI th Five Year Plan, the coal production is projected as under: Coal is the basic fuel used in the Indian cement industry. While it mainly provides the requisite heat and temperature, the ash content in the coal also combines chemically with the limestone to help form cement clinker.

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.
