A pulveried coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulveried 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.
