Overview of impacts on key Parameter Index (KPI) _ Holcim Norms

Reduction of kiln capacity by moisture

addition

2 t clinker / t water

Increase of heat consumption by

moisture addition

1.25 kcal/kg clinker / t water for 10000

TPD clinker plant

Reduction of kiln capacity by false air (or

transport air):

0.24 t clinker / 1’000 Nm3 of False Air

Increase of heat consumption by false air

(or transport air):

238 kcal / Nm3 false air or excess air

Reduction of kiln capacity due to in-

crease of oxygen when coarse solid LGF

alternative fuels are burnt

5.7% production loss per % O2 increase

Increase in heat consumption 2 kcal / % AFR (TSR)

Increase of heat consumption by in-

crease of oxygen:

1.8% heat consumption per % additional

O2

Conclusion
Before installing AF feeding and firing system quality of possible AFR`s along with
its impacts to be discussed properly with suppliers to have trouble free system.
