An air-cooled condenser includes an upper header for distributing a vaporous medium to be condensed, a lower header for collecting condensate, spaced finned tubes with outer fins, the finned tubes being connected in parallel between the upper header and the lower header and cooled by a cooling air flow, means for draining the condensate form the lower header and extraction means for removing non-condensible gases from the condenser. The lower header is also used for distributing the vaporous medium to the finned tubes, so that the vaporous medium id fed into the finned tubes through both the upper and lower headers, and the extraction means are connected to each of the finned tubes at its portion facing the cooling air flow.

Air-cooled condenser

A jet condenser of the type comprising a water chamber in a mixing chamber (24) and an after-cooler (52), wherein the water chamber is subdivided in a narrower upper water chamber portion (38a) and a broader lower water chamber portion (39b). The after-cooler (52) is fixed at the junction (66) of both water chamber portions (38a, 38b). Cooling water is injected into the mixing chamber (24) by nozzles (40) of the upper water chamber portion (38a) where it flows in vertical direction. By the reduced width of the upper water chamber portion (38a) flow resistance of steam flow in the mixing chamber (24) and, thereby, undesired subcooling is substantially diminished. (FIG. 3).
