Tاere is yet another Regulate purpose an operator has to help keep near check out above, that is, the coal-mill inlet temperature. The coal mill?�s functionality is not only to grind and pulverize but in addition to dry tاe coal. This is certainly accomplished by making use of warm excessive air through the clinker cooler, cooler air which can fluctuate quite commonly from a substantial of 650 C (1202 F) to the very low of two hundred C (393 F). From your prior dialogue of the combustion triangle. (Gas-Air-Heat), it may be seen tاat this kind of bigh air temperatures will be adequate to start a fire in tاe coal mill if this hot air temperature is permitted to fluctuate unchecked.
On some rotary kilns, the first air pipe is set a little underneath the middle of your kiln, in order to offset the flame buoyancy. Most kilns, even so, have amenities for adjusting the place of the main air pipe plus the burners, Consequently the operator can improve flame direction and, to some restricted diploma, change the form of the flame.
