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. the capacity of the id fan often limits the production capacity of the kiln. when the id fan reaches its.
Improved lime mud kiln control system.ime mud kiln consists of three sequential operating zones drying, heating, and calcining. to achieve proper calcination, lime is subjected to the calcining temperature forertain length of the kiln. since calcining is the final zone, any deviation from its required length causes variations in finished lime carbonate content.
Impurities in the makeup lime and refractory bricks used in the kiln, the efficiencies of slakers, causticisers, clarifiers and mud washers, and the burning conditions in the kiln. onry basis, lime mud typically contains about 95 wt cacondt of impurities. as lime mud moves through the kiln, the.
