Pulverised Fuel Mill Explosions

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.
