Dust explosion hazard of pulverized fuel carry-over ...

2005-6-30  This has led to an increase in fuel substitution (e.g. petroleum coke in place of coal) in pulverized fuel (PF) power plants. While fuel substitution has economic benefits in the form of fuel cost savings, it also changes the explosion hazard of the plant in both the fuel and ash handling systems.

Fire and Explosion Prevention in Coal Pulverizing Systems

2018-2-1  The design and operation of fuel handling and burning equipment must provide for maximum personnel safety and minimal property damage in the event of a coal/ air fire or explosion. In gas and oil fuel handling systems, explosive mixtures are minimized by keeping the air and fuel separate until they are combined at the point of combustion.

Pulverised Fuel - an overview ScienceDirect Topics

Pulverised-fuel (PF) technology is widely used for large coal-fired power plants. In such systems, the fuel particles are injected pneumatically at high velocity (the primary air is used as a carrier) through a burner nozzle into the furnace (Fig. 9.7).
