Advanced Emissions Control Technologies for Coal-Fired

Uncontrolled PM emissions from coal-fired boilers include the ash from combustion of the fuel as well as unburned carbon resulting from incomplete combustion. In pulverized coal systems, combustion is almost complete; thus, the emitted PM is primarily composed of inorganic ash residues. Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash).

NOx Emissions control for coal-fired boilers

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 since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. Coal is one of the most vital and abundant energy sources in the world.
