Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Higher the VM, the coal will burn better and burn nearer to the burner. VM varies from about 12% to 24% in the coals used at our stations. • Low VM coal requires a better PF fineness compared to high VM coal. This aspect is to be kept in mind while loading the mill and fineness readings are to be taken and monitored more frequently.
