“Blueprint” Your Pulverizer for Improved Performance
that article explained, the capacity of a coal pulverizer is a complex function of the fuel fineness desired, the coal’s Hargrove Grind-ablity Index (HGI), and the coal’s raw feed size and moisture content (see Figure 3 in “Finessing Fuel Fineness”). Plant operators can only improve throughput of a given mill
Improving Coal Pulverizer Performance and Reliability
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner. Coal that has not been pulverized into fine ...
