Fire Detection Methods for Coal Pulverizer Systems

2018-2-1  The Electric Power Research Institute (EPRI) performed an extensive investigation on fire detection for coal pulverizer or mill systems. The studies showed that there is an emergence of low rank, high reactive coals as a base fuel for power plants which is resulting in an increase in pulverizer system fires. Also, the EPRIget price

Pulverizer Fire and Explosions

Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire. The pyrite removal chute should be inspected often to ensure rejected material is removed from the under bowl area. Stoppage of pyrite chute flow can cause debris and-or coal get price

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.get price
