coal rotory cement kiln

An example of the thermal advantages of the use of suitable coal in a rotary cement kiln is given by Boateng. 14 A semi-dry rotarycement kiln consuming 1.44 kg/s of pulverised coal, with acalorific value of 30.4MJ/kg, is converted to burning natural gas (net calorific value of 44.6 MJ/kg) – what would be the effect of changing fuels? The result in the case given would be a ≈ 11.5% reduction in clinker …
