Burning Zone

The lower end of the rotary kiln is the burning zone, where cement components are heated to about 1300-1450°C (2372-2642°F). Measurement of the temperature in the burning zone is vital to maintain product quality and kiln efficiency.

The rotary kiln is inclined at a slight angle, so that the cement meal gradually passes from the cool end to the burning zone, before dropping out and cooling. This means temperatures vary within the kiln, making monitoring more difficult.

Maintaining the correct burning zone temperature is vital to driving off unwanted elements as gases and creating clinker of the required composition and anhydrous nature . Accurate temperature monitoring therefore plays an essential role in quality control of the cement and the energy efficiency of the kiln.
