Emergency inerting systems are preventive explosion protection technologies that prevent the ignition of fires and dust explosions and thus reduce the occurrence of hazardous incidents. These systems are (mostly) fixed standby systems used in order to avoid dust explosions and to suffocate and extinguish smouldering or glowing fires of combustible dust in silos, coal mills, bag houses, or similar aggregates by creating an inert atmosphere. In case of a CH4, CO, O₂, or temperature alarm the inerting process is initiated automatically by an independent PLC. Constant and reliable CH4, CO, O₂, and temperature measurements are absolutely necessary.

How to get your coal grinding system correctly protected? You will be surprised about what has gone wrong with fire and explosion protection of your system(s). Be sure about that! Evaluation of a coal grinding system’s fire and explosion protection, including the raw coal storage and the fine coal silo storage normally can be done in one day, mostly without having to stop coal grinding.

The evaluation will be done by way of touring the plant, making photos and having interviews with the people responsible for the operation. This will result in a comprehensive illustrated report and complete recommendations with explanations for necessary corrections. Ask for a free-of-charge offer indicating your airport.
