Coal Explosion In Pulverizer BluAutoService

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.

Also, the throat area must be properly designed to be compatible with the flow areas of the burner coal pipes and coal nozzles (Figure 8). Step 4. Properly maintain the classifier. Once the grinding

Coal mill pulverizer in thermal power plants

2012-11-17  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.

Raw Coal Spillage Or “Pyriting”

Coal dribble or spillage is raw coal that is rejected through the pulverizer’s pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be 7,000 to 7,500 Fpm when calculated on a free jet basis.
