Tاere is another control purpose an operator has to help keep close view more than, that is definitely, the coal-mill inlet temperature. The coal mill?�s functionality is don't just to grind and pulverize but will also to dry tاe coal. This is often accomplished by making use of incredibly hot surplus air within the clinker cooler, cooler air which can fluctuate quite regularly from the large of 650 C (1202 File) to a reduced of two hundred C (393 File). From your earlier discussion from the combustion triangle.
