IN A CEMENT PLANT WHERE DOES THE HEAT GO ??!!! + EXCEL SHEET FOR HEAT
For perpetual pyro process in a kiln the heatrequired is only heat of clinker mineral formation, ie., 380 – 400 Kcal/kg clinker. 280 – 350 Kcal/kg clinker is wasted which is about 40 – 45 % . The dream of design engineer is to make heat losses to minimum and how to optimize the heat consumption. The preheater heat losses

IMPORTANCE OF HEAT BALANCE IN CEMENT INDUSTRY …
Heat of evaporation of moisture = 597 kcal/kg. Therefore, heat of evaporation of raw meal moisture = 0.008*597 = 4.776 kcal/kg clinker. Heat of evaporation of coal moisture =. Let coal consumption be = x kg/kg clinker. Moisture in coal = 0.8 %. Moisture in coal in terms of kg/kg clinker. = x*0.8/100.

How Does Clinker Cooler Reduce Cement Production Energy Consumption
The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be …

It was found that about 40% of the total input energy was being lost through hot flue gas (19.15%), cooler stack (5.61%) and kiln shell (15.11% convection plus radiation). Some possible ways to recover the heat losses are also introduced and discussed. Findings showed that approximately 15.6% of the total input energy (4 MW) could be recovered.
