Cement Rotary Kiln Air Volume Control in Cement Production Line

In cement production line, vertical mill and Cement Rotary Kilns are the core equipments in cement production lines,I have said vertical mill in detail. Today, Let us find out more about the Cement Rotary Kiln, cement rotary kiln is at the time of work, the air volume control is close important, it directly affects the production of the finished product, the following specific as we explain how wind Cement Rotary Kiln control:

1.In order to form a circular flame stabilizing the flame. Cement Rotary Kilns primary air volume is too low, not only can not be carried into a secondary air within the wind, improving combustion flame speed, but also no extra momentum to form a circular flame, the flame is not conducive to stability, indirect combustion system is particularly important.

2.The burner production requirements can not be too high. A Cement Rotary Kiln burner air volume is too low, the corresponding pressure must be high, otherwise it will create momentum insufficient mixing of combustion and secondary air is difficult to effectively, while high pressure is bound to make the burner and fan made higher requirements.

3.The material must be burned completely. An amount of wind Cement Rotary Kiln is a case for the premise, that is shock-type flame not be occured, no carbon monoxide emissions.When the primary air volume is too low,it is not conducive to the air mixed with fuel,make the carbon incomplete combustion, thus reduces the thermal efficiency.

In summary, Air volume and wind speed of Cement Rotary Kiln are indeed important parameters. The role of secondary air is the key to accelerate the combustion flame speed and the formation of recirculation. Also,under the condition of air volume not enough, how to use the excellent burners generate enough wind speed, and in the cooler, the air force with the kiln hood Department, to achieve a reasonable control of the flame is the key.
