Cement Plants: Coal

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 ...

Table 3, Coal Classification, provides the coal classification according to the various ranks. Generally, coals used in cement plants are bituminous and sub-bituminous. Normally, in cement kiln systems, coal has to be dried and ground before firing. During combustion, volatile matter in coal evaporates and combusts as in the case of liquid fuels.

Cement kiln - Wikipedia

Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.
