Abstract
An air pollution control systemA includes a boilerthat burns fuel, an air heaterthat recovers heat of flue gasfrom the boiler, and a desulfurizerthat reduces sulfur oxides contained in the flue gasafter heat recovery by an absorbent, and waste-water supplying units Pto Pthat supply desulfurized waste waterdischarged from the desulfurizerto at least one of a path for supplying fuel to the boiler, inside of a furnace of the boiler, and the inside of a flue gas duct between the boilerand the air heaterare installed. With this configuration, an amount of desulfurized waste water to be returned into the flue gas duct per unit time can be increased as compared to conventional systems, without increasing the size of the entire air pollution control system.
