    OverviewHistoryHow it worksCurrent technologiesSteam locomotivesMerchant shipsSee alsoExternal links

    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 wit

    The PF exits the mill and is transported to the Burners in the Boiler; An advantage of this concept is that there is no contamination of the fuel gas as it enters the coal-fired boiler. The PF exits the mill and is transported to the Burners in the Boiler; An advantage of this concept is that there is no contamination of the fuel gas as it enters the coal-fired boiler. This allows a wide range of fuels to be co-fired within existing emission constraints while avoiding problems with ash quality.
