2-2 Lime Kiln Principles And Operations - tappi

the cold end of the kiln is the main gas moving fan. It pulls the combustion products, carbon dioxide from calcining, and the water vapor from the wet mud out of the cold end of the kiln. The ID fan is used to control the total air flow into the kiln for combustion, so controls the excess air or excess oxygen in the flue gas from the kiln.
