Apparatus for degassing a condenser operating in a thermal cycle

Abstract From the Canadian patent

A composite structure operating under a vacuum for condensing steam discharged from a turbine unit of a thermal power plant and de-gassing the condensate prior to feeding it back to the boiler for recycling comprises a condenser casing having an inlet for the steam which pases downwardly over a cooling tube bundle to effect its condensation. The condensate is then passed through a three stage de-gasifier to remove noncondensables such as oxygen. The first stage injects steam issuing from the subsequent stages into a condensate flowing downwardly on opposite sides of a gabled roof located beneath the tube bundle to accomplish an initial de-gasification; the second stage injects steam into a …
