cement kilns are expressed as weight of allowable emissions per unit of clinker production (kg/tonne). In determining allowable emission levels for cement kilns where major modifications are planned, consideration should be given to the offset of clinker production through the use of additives to clinker to produce cement, and the increase in energy

3.4 Burning in a kiln – formation of cement clinker. The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw mix.
