A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classifiion functions. The classifiion function plays the important role of ensuring that only fine particles are sent to the boiler.

Fire and Explosion Prevention in Coal Pulverizing Systems

There is experimental evidence that coal dust/air mixtures do have a lower explosive limit (, that concen tration of coal in air below which an explosion does not occur), but do not have an upper explosive limit as long as the coal/ air mixture can be considered a cloud. In practice, a fire occurring during normal pulverizer

 · Oxycoal combustion, in which an O2/CO2 mixture replaces air, is one of the few possible capture technologies to enable CO2 sequestration for existing coalfired boilers. Burning coal with relatively pure oxygen, together with recycled flue gases, can produce a highly concentrated (up to 95% CO2) flue gas stream, which makes carbon sequestration more economical.
