For rotary kiln, increasing calcination temperature is one of the main ways to raise flame temperature. Selecting high quality coal is based to increase the temperature of the flame material; the second is to improve the quality of the coal powder preparation. The main way is to control the good moisture and fineness of pulverized coal.

The pulverized coal with moisture between 1% and 1.5% can promote combustion, and can avoid the phenomenon of explosion in the process of storing pulverized coal, but excessive moisture can hinder the pulverized coal combustion, make the flame turn long, lower the flame temperature, and make the temperature of exhaust gas increase. So should be strict control moisture of coal, and is appropriate to be general between 1% and 1.5%.

The second is the strict control of the fineness of pulverized coal. If the pulverized coal is too thick, pulverized coal burns with a long time, or to extend, not burning pulverized coal is easy to fall into the clinker, to produce reducing atmosphere, causes the fuel with large pieces and knot ring in the rotary kiln, seriously reduces the quality of the clinker, even causes blockage cyclone crust.

Therefore, in the operation of rotary kiln, must fully pay attention to control the fineness and water of pulverized coal, which can increase the calcination temperature of rotary kiln.For rotary kiln, increasing calcination temperature is one of the main ways to raise flame temperature.
