It is absolutely necessary that every one the combustion reaction (burning from the gas) usually takes spot during the atmosphere in the burning zone. Impingement of partly burned gas on the feed mattress or kiln wall must be avoided constantly every time a kiln is being fired with coal or oil. Impingement of un­burned gas particles to the wall and feed mattress is don't just dangerous for the refractory and clinker and also functions as a nasty affect on fuel performance and kiln running security. Alignment from the burner, fineness from the coal, plus the velocity with which the fuel and the main air enter the kiln are The key factors governing impingement.
