Applications in Cement Manufacturing

• To measure false air(excess air) in the pre heater outlet, bag house, coal mill, and raw mill. ( ) p , g , ,This is checked to find out the air ingress.

• O2 CO CO2 in the rotary kiln inlet For every 1% excess O2 15 kcal of energy is consumed• O2, CO, CO2 in the rotary kiln inlet. For every 1% excess O2, 15 kcal of energy is consumed in excess per kg of clinker. In a 3500 tpd cement plant, this means 50 million kcal lost. Hence optimization of combustion becomes very important.

• O2, CO2 in the raw mill

• O2, CO, NOx, SOx in the coal mill

• O2, NOx, SOx at the bag house outlet

• Emission monitoring at stack to comply to regulations
