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.

In the present study, the potential use of the industrial waste residues, such as coal fly ash and clinker dust, was evaluated in inhibiting acid mine drainage generation from pyrite-rich wastes using non-saturated column experiments. Two columns (B and C) were filled with a mixture of industrial residues over pyrite-quartz sand (PS), while one …
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 …
More sustainability for the cement industry
Clinker is the most important component in making cement a hydraulic binder. For years, cement manufacturers have been striving to reduce the so-called clinker factor – the proportion of clinker in cement – by adding additives. This is because the higher the proportion of clinker, the more CO 2 is released during cement production.
