Improving Coal Pulverizer Performance and Reliability

Description Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

COAL MILL PULVERIZER in THERMAL POWER .

4.1.Drying The coal that is passing through a pulverizer is entrained by the use of hot air usually from the air heater. During the pulverization process the surface area of the coal particles increases dramatically exposing fresh coal to the entrainment air. The inherent and surface moisture of the coal is reduced by the exposure to hot air.

Pulverized Coal Explosions in the U.S. Utility Industry

Ignition events remaining within the coal pipe created only weak pressure rise, while ignition events within a simulated pulverizer volume created explosions exceeding 70 bar gage (1015 psig). These experiments showed that explosion characteristics depend on dust concentration, ratio of pulverizer volume to coal pipe area, as well as coal type.
