Modeling and outlet temperature control of coal mill …

Poor dynamic performance of coal mill causes difficulties in maintaining the frequency, boiler pressure and temperature of the plant. This paper presents development and validation of coal mill model for improved coal mill control. The parameters required to

what is the max coal mill outlet temp

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 restricted to a lower level depending on percentage of volatile content in coal.

Mill operating parameters determine the mill operating window which provides the limits in which a mill best operates, and outside of which constraints are experienced. The mill operating window is plotted using the mill operating parameters, such as drying limit, erosion limit, milling capacity limit, tampering limit, flame stability limit and pulverised coal transport.
