Boiler Performance and Mill Outlet Temperature

11 11 2009  Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler Coal being a heterogeneous fuel varies in its properties the variation depends on many factors like type of origin of coal formation etc.Two major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.

coal mill outlet temp maximum maintain how much

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.

Review of control and fault diagnosis methods applied to

01 08 2015  01 08 2015  Coal mills or pulverizers play a very essential part in the coal fired power production system Coal mills grind the coal into fine powder and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion Mills can be a bottleneck for the power generation process.

How it works The raw coal enters the mill via a feed screw and is discharged onto the rotating grinding table The rotation of the table accelerates the flow of material towards the grinding track where the coal is ground between the table and the three rollers.
