Tاere is yet another Management operate an operator has to maintain close look at more than, that is definitely, the coal-mill inlet temperature. The coal mill?�s purpose is not merely to grind and pulverize but additionally to dry tاe coal. This really is accomplished by making use of sizzling extra air from the clinker cooler, cooler air which may fluctuate fairly frequently from the high of 650 C (1202 F) into a low of 200 C (393 File). From your prior dialogue on the combustion triangle. (Fuel-Air-Warmth), it can be noticed tاat this kind of bigh air temperatures could be enough to begin a fire in tاe coal mill if this warm air temperature is permitted to fluctuate unchecked.
a shorter plume (earlier ignition) may be attained by grinding the coal to some · greater floor spot; that is definitely, grinding the coal finer. Earlier ignition on oil fired kilns may be accomplished by rising the temperature in the gas oil, and by deciding upon a scaled-down oil burner opening (orifice, or suggestion measurement) this sort of tl1at the oil are going to be greater atomized.
