Tاere is yet another Command function an operator has to help keep close observe in excess of, that is definitely, the coal-mill inlet temperature. The coal mill?�s purpose is not just to grind and pulverize but also to dry tاe coal. This is often accomplished by utilizing warm excessive air with the clinker cooler, cooler air which might fluctuate fairly frequently from a higher of 650 C (1202 File) into a lower of 200 C (393 File). In the past discussion of your combustion triangle. (Gasoline-Air-Heat), it could be noticed tاat this sort of bigh air temperatures might be sufficient to begin a fire in tاe coal mill if this very hot air temperature is permitted to fluctuate unchecked.

Never, the less burning gas in the kiln is not just severe on the elements. Furthermore, it will take its toll over the kiln bricks. So, Permit?�s take a look now at how kilns perform whenever they depend on burning fuel.
Even so, immediate-fired kilns extra frequently are forced, by program style and design, to function with velocities of involving forty five-66 m/s (9,000??13,000 ft/min) which largely deliver a relatively lazy swirling flame. A lot of operators on this kind of immediate-fired kilns have unsuccessfully tried to decrease the burner orifice measurement (i.e., to improve the suggestion velocity) and seasoned coal evacuation problems within the mill.
