MULTISTAGE PRESSURE CONDENSER AND STEAM TURBINE PLANT EQUIPPED WITH SAME

摘要

Provided are a pressure bulkhead (4) that has a plurality of holes (8) and that divides a low-pressure chamber (2) at low pressure in a vertical direction; a cooling-tube bank (5) that is provided in an upper section of the low-pressure chamber (2) partitioned by the pressure bulkhead (4) and that performs heat exchange with low-pressure steam guided to the low-pressure chamber (2) by coolant introduced therein so as to condense the low-pressure steam to low-pressure steam condensate; a reheat chamber (6) that serves as a lower section of the low-pressure chamber (2) partitioned by the pressure bulkhead (4) and that stores the low-pressure steam condensate falling from the holes in the pressure bulkhead (4); high-pressure-steam introducing means (11) for introducing high-pressure steam within a high-pressure chamber (22) at high pressure to the reheat chamber (6); and a plurality of plate members (10) that are arranged parallel to each other below the pressure bulkhead (4) and that extend in a falling direction of the low-pressure steam condensate falling from the holes (8) in the pressure bulkhead (4). The plate members (10) each have a cross-sectional shape, as sectioned in the falling direction of the low-pressure steam condensate, having one or more protrusions and recesses.
