The fossil fuels used to fire the clinker kilns is a major source of greenhouse gases. Additionally, the heating of limestone causes its own carbon emissions. The estimate is that for every kilogramme of cement manufactured, between 0.5kg and 0.9kg of carbon dioxide equivalent (CO₂e) is emitted.

Kilns need to be designed to meet limits for emissions of nitrogen oxides and unburned carbon compounds such as CO. Flameless combustion: The pyrogas is introduced on the outside of the air jets, and air and fuel are premixed with hot exhaust gases. Conditioned fuel and air burn cleanly, at lower temperature, without a flame.

Pre-calciner kilns are shortest in length, as 90-95 % calcination is completed outside the kiln. L/D of three tyre kiln is between 14-17 and for new kiln like 'Rotax kiln' it is only 12-13. Kilns are commonly supported on three supporting stations. Each supporting station has 2 rollers and 4 …

A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;; grinding the resulting clinker to make cement (see Cement mill).; In the second stage, the rawmix is fed into the kiln and gradually heated by contact with …

Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
