Fire and Explosion Prevention in Coal Pulverizing Systems

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.GE says it's going green. Overseas, it's still pushing coalMar 02, 2020· In 2015 GE made an ill advised bet on the future of fossil fuels, paying $13 billion to acquire a French energy company, Alstom, and doubling its fleet of coal plant turbines.Coal Drying Improves Performance and Reduces Emissionscoal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill.
