Mill Inerting and Pulverizer/Mill Explosion Mitigation

flaming, smoking or smoldering coal inside the mill means a mill explosion could be occur at any time. • Any burning or smoldering material inside the mill can evolve into an explosion because they provide an ignition source if the air to fuel (coal) ratio is elevated or higher than desired.

Isolation Flap Valves For Explosion Isolation

Utilizing a lightweight yet high-strength flap mechanism, the SNR valves quickly react to the initial stages of an explosion event through sensitive detection of pressure changes. By slamming shut against extreme pressures surging up to 1 bar, they effectively block detonation waves from traveling farther down the connected piping.
