Tاere is another Regulate functionality an operator has to keep near observe about, that is, the coal-mill inlet temperature. The coal mill?�s perform is not simply to grind and pulverize but also to dry tاe coal. This really is accom­plished by making use of scorching excess air within the clinker cooler, cooler air which might fluctuate fairly often from a superior of 650 C (1202 F) to some minimal of two hundred C (393 F). In the past discussion from the combustion triangle.

It is absolutely vital that all the combustion response (burning on the gas) can take location during the atmosphere on the burning zone. Impingement of partly burned gasoline on the feed bed or kiln wall have to be prevented constantly whenever a kiln is remaining fired with coal or oil. Impingement of un­burned fuel particles around the wall and feed bed is don't just harmful into the refractory and clinker and also functions as a bad impact on gas efficiency and kiln running security. Alignment of your burner, fineness from the coal, as well as the velocity with which the gasoline and the key air enter the kiln are The most crucial aspects governing impingement.
