Improving Coal Pulverizer Performance and Reliability

2017-4-3  Raw coal enters the top of the pulverizerthrough the raw coal feed pipe. The rawcoal is then pulverized between the roll androtating ring. Hot air is forced in through thebottom of the pulverizing chamber to removeunwanted moisture and transport the coaldust up through the top of the pulverizerand out the exhaust pipe directly to theburner. Coal that has not been pulverizedinto fine enough particles cannot be blownout of the top of the unit; it falls back to thering and roll to be further pulverized.
