CONDENSER AND STEAM-TURBINE PLANT PROVIDED THEREWITH

摘要

This condenser (30) is provided with the following: a set of heat-transfer tubes (32); a main body (35) that covers the heat-transfer tubes; an intermediate body (41) that forms a primary steam passage (42) for guiding exhaust steam (ES) from a steam turbine (3) to the set of heat-transfer tubes in the main body; and a bypass steam receiving section (51) that receives bypass steam (BS), i.e. steam that has bypassed the steam turbine, and guides the bypass steam to the set of heat-transfer tubes in the main body. The bypass steam receiving section (51) is located outside the primary steam passage (42), and an opening in the main body (35) that is opposite to the bypass steam receiving section (51) is formed at a position where the bypass steam (BS) flows into the set of heat-transfer tubes (32) mainly from a region (34) different from an inflow region (33) through which the exhaust steam (ES) mainly flows into the set of heat-transfer tubes via the primary steam passage.
