Mill Steam Inerting System Review and Performance Validation

Steam is commonly employed in the power industry for coal pulverizer system inerting, due to its ready availability and cost effectiveness. During a ball tube mill start-up, Riley Power Inc. recommends a specified steam flow rate to be introduced and mixed with the primary air entering the mill to establish an inert atmosphere in the mill. During mill shut down, the same inerting process ...

Coal pulverizing system explosions during the last few years have pointed to the need of developing inerting systems for preventing such incidents. The greater use of western subbituminous coals (with their higher tendency for spontaneous ignition) is a contributing factor to the increased frequency of coal pulverizer explosions.

PULVERIZER MILL PROTECTION SYSTEM - INNOVATIVE

Steam inerting can be effective in displacing oxygen in the pulverizer, but it must be insured that the steam does not condense due to falling below saturation temperature and pressure. Generally, steam cannot be relied upon to extinguish a fire. Explosion suppression and venting solutions react to dust explosions by either rapidly combining the combustible coal dust with a noncombustible dust ...
