    Detecting moving fires on coal conveyors - Power Engineering

    G. Detection equipment can be installed to monitor carbon monoxide (CO) buildup in the pulverizer, cyclone, storage bin, or dust collector. The design of the carbon monoxide monitoring system is based on the fact that CO buildup is related directly to the oxidation rate of the coal.Feb 24, 2012 Coal Combustion Theory. Combustion is a rapid chemical reaction between fuel and oxygen. When combustible elements of fuel combine with O 2, heat energy comes out. During combustion combustible elements like Carbon, Sulfur, Hydrogen etc combine with oxygen and produce respective oxides. The source of oxygen in fuel combustion is air.
