Regarding specific heat consumption (Kcal/Kg of Clinker) of kiln if …
There may also be a reduction in kiln production rate if your ID fan capacity is limited, which would also result in an increase in heat consumption. Also the very low ash of petcoke means that less clinker is produced per tonne of kiln feed. This also increases the specific heat consumption. Regards, Ted. Reply
