It is completely crucial that every one the combustion response (burning from the gas) usually takes spot from the environment of your burning zone. Impingement of partially burned gas on the feed mattress or kiln wall needs to be avoided constantly every time a kiln is being fired with coal or oil. Impingement of unburned fuel particles within the wall and feed bed is not merely harmful for the refractory and clinker but additionally acts as a bad influence on fuel effectiveness and kiln running balance. Alignment on the burner, fineness on the coal, as well as velocity with which the gasoline and the main air enter the kiln are A very powerful components governing impingement.
