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. Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw co

Pulverized coal-fired boiler - Wikipedia

Pulverized coal-fired boiler. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to ...
