Types of boiler coal pulverizers

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal

    Pulverized-coal (PC) boilers offer a more efficient alternative to stokers for burning coal. PC boilers are used in large ICI units. In PC boilers, the coal is pulverized to very small particles in large devices called pulverizers or mills. These coal particles are then blown with air into the boiler through a “burner,” where they are then

    Pulverized Coal Fired Steam Boilers is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels

    Coal-fired boilers can be further divided based on the equipment used to fire the boiler. The three major coal-fired boiler subclasses are pulverized-coal (PC) fired, stoker-fired, and fluidized-bed combustion (FBC) boilers. Ł Boilers are occasionally distinguished by their method of fabrication. Packaged boilers
