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
Raw coal enters the top of the pulverizer through the raw coal feed pipe The raw coal is then pulverized between the roll and rotating ring Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner
