Pulverized coal-fired boiler - Wikipedia

The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of the pulverized coal is controlled by computers, and is varied according to the boiler demand and the amount of air available for drying and transporting fuel.
