Abstract: A method and apparatus are provided for reducing quench water required by a wet electrostatic precipitator. The apparatus includes a wet electrostatic precipitator and an evaporator in flow communication with the wet electrostatic precipitator to evaporate at least one portion of bleed water discharged from the wet electrostatic precipitator into steam. The method includes directing at least one portion of bleed water discharged from the wet electrostatic precipitator to an evaporator and directing at least one portion of flue gas from a boiler to the evaporator. The energy of the at least one portion of flue gas is used to evaporate the at least one portion of the bleed water into steam. The steam is directed to the wet electrostatic precipitator. The at least one portion of flue gas is directed from the evaporator to the wet electrostatic precipitator.

Abstract: A method and apparatus are provided for reducing waste effluent from a system including a boiler and a wet electrostatic precipitator, the waste effluent having blow down water discharged by the boiler during a blow down operation and bleed water discharged by the wet electrostatic precipitator. The method includes collecting the blow down water and providing it to the wet electrostatic precipitator as a makeup water supplement, evaporating a portion the bleed water and leaving residual bleed water, providing the evaporated bleed water to the wet electrostatic precipitator as a further makeup water supplement, and using the residual bleed water to quench ash produced by combustion of solid fuel by the boiler. The apparatus includes an evaporator that provides direct contact between hot boiler flue gas and the bleed water such that a portion of the flue gas is quenched before being provided to the wet electrostatic precipitator.
