Pulverizer Fire and Explosions

Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill “puffs”. 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.

Fire and Explosion Prevention in Coal Pulverizing Systems

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal

Dust explosion Wikipedia

Mining of coal leads to coal dust, and flour mills likewise have large amounts of flour dust as a result of milling. A gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 18 workers at the Washburn A Mill and another four in adjacent buildings.

Comparative study of the explosion pressure

Coal dust explosion accidents often cause substantial property damage and casualties and frequently involve nano-sized coal dust. In order to study the impact of nano-sized coal on coal dust and methane–coal dust explosions, a pipe test apparatus was used to analyze the explosion pressure characteristics of

DSS055: Coal Mill Safety In Cement Production Industries

Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills
