Pulverizer Fire and Explosions

Explosions in a pulverized coal system are normally called “puffs.” A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature. Mill puffs most often originate in the under bowl area and can cause very destructive damage to the primary air ducting.

Coal-seam fire Wikipedia

A coal-seam fire is a burning of an outcrop or underground coal seam. Most coal-seam fires exhibit smoldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years.

Fire and Explosion Risks in Cement Manufacturing

A coal fire can arise as a result of natural combustion caused by oxygen absorption at the outer and inner surface of coal leading to oxidation. Oxidation is an exothermic reaction that makes the temperature of the coal to go up and if the coal pile exceeds 800C, ignition can take place.

Coal Fire Detection Product Range

Mill Fire Detector Monitors the levels of carbon monoxide inside the mill and storage silos. A rapid rise in the levels indicates that combustion is underway. If CO levels reach the pre-set limits then alarms are triggered and preventative action can be taken before a fire starts or an explosion occurs. Fires and explosions can lead to mills having to be replaced, surroundings being repaired (or replaced) and
