PH adjustment of power plant cooling water with flue gas/fly ash

DWPI Title: Method for operating power plant, involves condensing fluid heated in vessel and used to power turbine with pH modified cooling medium in condenser
Abstract: A system including a vessel including a heat source and a flue; a turbine; a condenser; a fluid conduit circuit disposed between the vessel, the turbine and the condenser; and a diverter coupled to the flue to direct a portion of an exhaust from the flue to contact with a cooling medium for the condenser water. A method including diverting a portion of exhaust from a flue of a vessel; modifying the pH of a cooling medium for a condenser with the portion of exhaust; and condensing heated fluid from the vessel with the pH modified cooling medium.
Use: Method for operating power plant.
Advantage: The exhaust from flue is diverted to one or more of these locations at different times in an electricity producing process, is provided.
Novelty: The method involves diverting a portion of exhaust gas from a flue of a vessel (120). The pH of a cooling medium is directly modified for a condenser (160) with the portion of exhaust gas. A fluid heated is condensed in the vessel and used to power a turbine (140) with the pH modified cooling medium in a condenser. The vessel is a boiler fluidly coupled to a turbine. The portion of the exhaust gas is sufficient to lower the pH of the cooling medium.
