Mass Balance of a Kiln System Cement CO2 Protocol

Bypass dust leaving the kiln system requires separate reporting: line022; CKD recycling remains within the mass balance. Thus, it does not need additional reporting. The mass flow of CKD Cement kiln dust leaving the kiln system (and crossing the red boundary in the diagram) needs to be accounted for additionally: line023.

Cement Kilns: A Ready Made Waste to Energy Solution

The plant utilises waste heat from the kiln process to dry the sludge from 80% moisture down to 40%. In a next step the dried sludge is 100% recovered in the cement kiln. The organic part is a fuel replacement for the coal, where-as the mineral part of the sludge (on dry basis around 40%) is replacing virgin raw materials.

Cement Kilns: Size Reduction and Grinding

Mills were said to make around 4 t/h at a fineness typical of 1890, and drew around 80 kW, so the energy consumption of 20 kWh/t was about two-thirds of typical flat-stone cement. However, critics suggested that the cement, ground closed-circuit to a coarse residue specification, contained correspondingly less "flour" than flat-stone cement
