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 EPRI

Fire and Explosion Prevention in Coal Pulverizing Systems

2018-2-1  Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire. The coal/ air mixture enters the furnace through a burner nozzle at velocities in excess of the flame speed. Thus, the flame front is held stable at a distance away from the end of the nozzle where the coal/ air mixture velocity has slowed and is equal to the flame speed.
