Fire Detection Methods for Coal Pulverizer Systems

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 study concluded that reducing the frequency of fires would reduce the ...
