Cement Plants: Coke

Petcoke differs also in that it is tougher to grind, and there is a trend towards the use of more sophisticated fuel grinding circuits to cope with this. Despite these problems, cement kilns have been run on pure petcoke, and a 50:50 coal:petcoke mix is a fairly normal fuel mix nowadays. The increase in the use of petcoke has of course been due to the fact that "green" coke with metals ...

As petcoke has a better vitality content, petcoke emits between 30 and eighty p.c extra CO2 than coal per unit of weight. The distinction between coal and coke in CO2 production per unit vitality produced depends upon the moisture in the coal (will increase the CO2 per unit vitality-heat of combustion) and unstable hydrocarbon in coal and coke (lower the CO2 per unit energy).
