Cement industries have kilns of length varying from 70 to 80 m where clinker generation occurs. Typical Rotary Kiln surface temperature in a cement industry varies from 150 deg C to 400 deg C. The energy from the rotary kiln at temperatures around 150-400 deg Celsius presently is being radiated into the atmosphere.
