Cement Plants: Coal

2019-11-16  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

Use of coal as a fuel in cement plants and its impact on

2016-7-30  76.36 g of coal should be pulverized with raw meal to produce one kilogram of the clinker, which is equivalent to 1.55 kg of the raw mix. This can also be calculated that for one kilogram of raw meal, 49.27g of coal is required. But the observed heat required in cement kiln is 850 kcal/kg, which is almost double to that 420 kcal/kg.

Coal utilisation in the cement and concrete industries

2013-1-1  The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
