Abstract:
1. A method for effective venting of a condenser of the type having a circulating water inlet water box and outlet water box coupled with interconnecting water filled tubes passing within a shell containing steam to be condensed to form a condensate, an air removal section (“ARS”), the improvement for one or more of reducing dissolved oxygen (DO) or other gases content in said condensate, reducing condensate and feed water side corrosion, reducing excess condenser pressure in the condenser, or improving the condenser heat transfer coefficient by eliminating or reducing zones that promote subcooling resulting from an air bound zone or a stagnant zone, which comprises the steps of: replacing one or more of water filled tubes within said air bound zone or said stagnant zone with one or more vent tubes in connection with a source for venting air or other gas from said air bound zone or said stagnant zone; or providing one or more vent tubes in connection with a source for venting said air bound zone or said stagnant zone; wherein one or more vent tubes having apertures are inserted into said zones that promote subcooling such that said apertures are located within said zones that promote subcooling; and connecting said one or more vent tubes to a suction device for removing one or more of non condensable gases or water vapor from said zones that promote subcooling; and wherein said vent tubes are formed by replacing one or more water filled tube extending to within said zones that promote subcooling with vent tubes having apertures and connected to said suction device.
