clinker burning in the cement process of the primaries

Cementmanufacturing is an energy intensive activity and the choice and mix ofprimaryand alternative fuels affects both the environmental impact and economics of theprocess. Total energy cost can represent 65-75% of the variable costs in theprocess. To save energy, moderncementplants preheat the mix of raw materials before they enter the ...

The idea of precalcination is, to let thisprocesstake place before the meal enters the rotary kiln by introducing that part of the fuel, i.e. up to 65%, into a stationary reactor. Because the combustion air (tertiary air) is drawn through a separate duct parallel to the kiln directly from the cooler, the rotary kiln operates at significantly ...

Determination of the material recyclable share of SRF
Determination of the material recyclable share of SRF

Solid recovered fuel (SRF according to EN 15359) is frequently used to substituteprimaryfuels required for theclinker burning process in the cementindustry. Since the ash that is formed during the combustion of the SRF is directly incorporated into the product portlandcement clinker, thisprocessis also referred to as “co-processing”.

Clinkerization  CementPlant Optimization
Clinkerization CementPlant Optimization

Clinkerfree lime (CaO f) should be as high as possible to avoid hardburningofclinker, but safely below value, inviting mortar expansion; normally, between 0.5% and 1.5%. Free lime indicates incompleteclinker burning, therefore should be monitored regularly and maintained closely in the acceptable range.
