Explosion venting mitigates a deflagration by keeping the pressure below a level that could damage the milling system equipment. Venting provides a truly passive mitigation solution with very low maintenance requirements. In addition to venting the mill, you must also vent the plenum under the mill, if applicable. Downstream protection
an explosion. Scrap metal in a coal mill is particularly dangerous during mill shut down or start up. Coal Mill Operation . Fires or explosions most likely occur during startup and shutdown of a coal mill system. If a small amount of coal remains in the mill after it is shut down, it slowly increases in temperature.
