It is absolutely important that each one the combustion reaction (burning on the fuel) requires location within the environment of the burning zone. Impingement of partly burned fuel upon the feed mattress or kiln wall has to be prevented constantly whenever a kiln is getting fired with coal or oil. Impingement of un­burned gas particles on the wall and feed bed is don't just destructive to your refractory and clinker but additionally functions as a nasty affect on gas performance and kiln operating steadiness. Alignment of your burner, fineness from the coal, plus the velocity with which the fuel and the first air enter the kiln are The main elements governing impingement.
