    Mathematic Modeling and Condition Monitoring of Power ,Boiler Performance and Mill Outlet Temperature

    coal output from the mill at the flow rate W pf should be equal to the total mass of the raw coal mill flowing into the mill at the flow rate W c eventuallyThe 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 This is mainly done to avoid mill fire and mill explosion.
