Pulverized coal-fired boiler - Wikipedia

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 use the whole volume of the furnace for the combustion of solid fuels.

Pulverized Fuel Fired Boilers Introduction | ESN

Jun 18, 2016· The coal is ground (pulverized) to a fine powder in the coal mills so that less than 2 per cent is +300 micro metre (μm) and 70-75 per cent is below 75 microns, for bituminous coal. The pulverized coal is blown with part of the combustion air into the boiler plant through a series of burner nozzles. Secondary and tertiary air may also be added.
