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 furnacefor the combustion of solid fuels. Coal is ground to the size of a fine grain into the boiler, mixed with air and bur
