Five Factors Affecting Pulverized Coal Combustion in Lime Rotary Kiln

Rotary kiln production equipment is relatively simple, while the construction funding is relatively low, calcined lime can choose several kinds of fuel, coal, natural gas, etc., the use of coal will inevitably use pulverized coal burners, affect the five major lime rotary kiln pulverized coal combustion.

Five Factors Affecting Pulverized Coal Combustion in Lime Rotary Kiln

Rotary kilnproduction equipment is relatively simple, while the construction funding isrelatively low, calcined lime can choose several kinds of fuel, coal, natural gas, etc., the use of coal will inevitably use pulverized coal burners, affect the five major lime rotary kiln pulverized coal combustion. And the factors areas follows:

1. Pulverized coalwith high moisture content is not only difficult to grind, but also vaporizeswhen it is burned, absorbing a lot of heat. General pulverized coal watercontrol is below 1%.

2. In theproduction of ash cement, the ash content of coal should be controlled andstabilized, otherwise it will affect the firing condition.

3. Fixed carbonand carbon is the main chemical source of thermal energy generated inpulverized coal, the fuel must be given a certain amount of excess air toprevent incomplete combustion.

4. The combustioncapacity of volatile coal is directly proportional to the volatilization, andthe high-volatile coal powder is easy to burn.

5. Calorific valueIt is the most important measure of fuel performance. Calorific value isdivided into high calorific value and low calorific value. The low calorificvalue takes into account the evaporation of moisture in the fuel and the heatloss when the hydrogen is combusted into water vapor.

The above are thefive factors that affect the pulverized coal combustion in the lime rotarykiln. They play an important role in the entire production process, especiallythe preheating of the entire work. For more information about lime kilnequipment, please email directly:ec03@zkcorp.com.
