Cement kiln dust
Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2).In the next step of the so-called clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2), …

An analysis of the use of life cycle assessment for waste co
The market of clinker has changed significantly, and a variety of cement products are being produced with reduced clinker content (i.e. clinker factor). An objective of 0.71 clinker factor is regarded as the industry goal. Also, new formulations of cementitious materials without clinker have been developed. • To use waste-derived fuels.

Clinker factor determines the CO2 footprint of cement
In OPC, clinker factor is ~90 per cent thus, it has a carbon footprint of around 800 – 850 kg/MT of cement. When clinker is replaced with SCMs, the CO2 emissions are reduced as SCMs don't have embodied carbon emissions. That is why blended cement have much lower carbon footprint than OPC. Currently in Portland Slag …

Clinker Production
The clinker cooler exhaust is at a temperature near 200°C and is typically used for preheating the kiln or other parts of the clinker production process. The ORC and Kalina cycles have also been considered for use to recover the waste heat from the clinker cooler. The sCO 2 cycle could also be considered for both waste heat streams.
