Tاere is an additional Management purpose an operator has to maintain shut watch in excess of, that is certainly, the coal-mill inlet temperature. The coal mill?�s purpose is not simply to grind and pulverize but additionally to dry tاe coal. This really is accomplished by making use of incredibly hot extra air in the clinker cooler, cooler air which might fluctuate really often from the substantial of 650 C (1202 File) to your minimal of two hundred C (393 F). Through the past discussion of the combustion triangle. (Gas-Air-Warmth), it may be seen tاat this kind of bigh air temperatures could well be enough to begin a fire in tاe coal mill if this warm air temperature is allowed to fluctuate unchecked.
