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).
Boiler and Combustion Controls Biofuel Combustion Control In an effort to shift to sustainable, environmentally responsible energy production, many companies are shifting to renewable biomass and away from burning nonrenewable carbonrich fuels such as coal and oil.
