Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (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

Hard coal is a sedimentary rock which was formed by deposition and carbonization of plant remains. It is hard and resistant. More than 50% of its weight is made up by carbon. Therefore it is classified as high-rank coal. Other fossil fuels like sub-bituminous coals with high moisture contents as well as brown coal and lignite are lower ranked.
