Coal mill inerting system (O2) Inerting systems avoid dust explosions and smouldering fires in silos, coal mills and filter equipment by creating an inert atmosphere. In the case of abnormal levels of carbon monoxide (CO), oxygen or heat, the inerting process is initiated automatically through a process-control system
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
The fully-automatic RSC inert control unit was supplied as an intelligent interface between the gas analyser system and the CO2 inerting system. The RSC controls all parameters of the gas analyser system, coal mill temperature sensors, CO2 inerting system, valves and flaps of the entire coal …
Re: firefiting system in coal mill. If the coal mill temp goes high, it can ignite the coal and result in explosion inside the mill and components. Thats why the CO2 is injected into the mill to create a inert condition , means to reduce the Oxygen content inside the mill to avoid any firing/explosion
