The only difficult thing in calculating the combustion efficiency is how to pursuit the optimal number. Combustion efficiency is characterized by the overall fuel burning in the combustion chamber. While the control parameters are used to ensure the overall fuel burning, is the amount of air combustion (air excess) coming out through the stack.

The Coal mill performance monitoring - SlideShare

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is ...
