Coal Based Fuel Feeding System for Boiler

The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.

1 Despite the fact that mining is associated with a large number of risk factors for accidents that threaten the lives of many people, and not completely predictable processes in the Earth's crust, there is a consensus that the root cause of emergencies (gas explosions, landslides, rock bumps, rock bursts, flooding, etc.) is the human factor.

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 will

Knowing how a fire spreads is essential to find the root cause of a fire. Just like all forms of heat, fire can spread in three ways: conduction, convection and radiation. Conduction occurs when there is direct contact with the fire or hot objects, and convection is when heated air or gaseous-combustion products contact combustible materials.
