re Regardingspecific heat consumption(Kcal/Kg ofClinker) ofkilnif we use 100% Pet Coke with 1% residue on 90 micron in place of coal. Hello Rajuram, Generally speaking, the use of petcoke results in a higherspecific heat consumptionthan coal. This is primarily due to the higher O2 levels required in thekiln inletto prevent build-ups and blockages resulting from the very high sulphur content of petcoke …

Cement Kiln - an overview | ScienceDirect Topics

Cement kiln dustis a major waste to the air environment and needs collection and disposal to protect the surrounding air. Kessler (1995) reports that typically each percent of dust wasted increases thespecific heat consumptionby about 0.7% and decreasesclinkerproduction by 0.5%. He gives the dust losses costs as Cwtl = $4.08/ton ofcement, due to the loss of raw material; Cwt2 = $4.59/ton by feed …
