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. Mill puffs or explosions can be very dangerous resulting in serious damage to the pulverizer system or injury to personnel. When conditions that promote mill puffs
Coal dust suspended in air is explosive—coal dust has far more surface area per unit weight than lumps of coal, and is more susceptible to spontaneous combustion. As a result, a nearly empty coal store is a greater explosion risk than a full one. The main attempts at prevention include using safety lamps, adding stone dust coffers to mine galleries to dilute the coal dust, watering workings

Bag filters used for the coal mill rank as one of the highest fire and explosion hazards in cement plants, due to the small particle size of the crushed coal. 3) Electrostatic Precipitators Build-up of explosive mixtures like finely dispersed coal dust in air, or carbon monoxide in air can result in an explosion hazard in Electrostatic Precipitators.

1977-The worst flour mill explosion on record occurred in Westwego, Louisiana when a buildup of grain dust came in contact with static electricity. The explosion blew the top off the silo, and caused another 48 silos to catch fire. 36 workers were killed in this disaster, many from being crushed by the collapsing silos. Building code reforms for grain silos were based off this event. 1979-The

"First and foremost is our concern for the safety of our employees, contractors, and visitors on our mill
Coal Mill Safety parameters: Position of Explosion vents. Operational readiness of quick shutoff dampers. Inertization section readiness (N2, CO2 pressure in bars) Mill Inlet Temperature (0 C). Mill Outlet, bag filter outlet Temperature (0 C). O2 + CO Percent at bag filter outlet and in fine coal bins. Bag filter hopper and fine coal bin temperature (0 C). Elements of Coal Grinding System
05.07.2016· If there's dust in the area, the primary explosion will cause that dust to become airborne. Then, the dust cloud itself can ignite, causing a secondary explosion that can be many times the size and severity of the primary explosion.
cleaned air enters the mill fan. For more explosive types of coal such as lignite, the filter may be installed on the pressure side of the fan. This eliminates ingress of false air into the filter and keeps the level of oxygen in the filter and the recirculated gas at a minimum.

What Causes Flour Mill Explosions? Flour dust combined with factors like an ignition source, confined space, dispersion and oxygen are the main culprits behind flour dust explosions. The process of flour production can create an environment where all these elements unite. As such, flour dust acts as a fuel source when mixed with oxygen which can result in a fire when confined in a limited

In a tightly enclosed space, the sudden depletion of oxygen can cause asphyxiation. Where the dust is carbon based (such as in a coal mine), incomplete combustion may cause large amounts of carbon monoxide (the miners' after-damp) to be created. This can cause more deaths than the original explosion as well as hindering rescue attempts.
