    Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 m (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil
