Coal Pulverizer Explosions ASTM International

Ignition events that remained within the coal pipe created only weak pressure rise, while ignition events within the simulated pulverizer volume created explosions exceeding 70 bars (7000 kPa). These experiments showed that explosion characteristics depend on dust concentration, ration of pulverizer volume to coal pipe area, as well as coal type.
