摘要： PURPOSE:To prevent the water chamber of the condenser from being subjected to an excessively heavy load due to an earthquake or the like by a method wherein in the steam turbine condenser provided with flexible joints between the trunk and the water chamber thereof, the water chamber is made movable in the longitudinal direction of a cooling pipe but is restrained to move in the direction normal to the cooling pipe. CONSTITUTION:The five quakeproof means 10 are attached to the trunk 1 of the condenser at positions adjacent the water chamber 4' with one end of each of the quake- proof means 10 held across each of the flexible joints 5. The quakeproof means 10 are so formed that they can move in the longitudinal direction of the cooling pipe 2 but are restrained to move normal to the cooling pipe 2. With the above structure, when the movable side of the water chamber 4' is subjected to the force of inertia in the direction normal to the cooling pipe 2, the counter-force is born upon by the quakeproof means 10 so that no excessive load is applied on the flexible joints 5, a pipe plate 3 and the cooling pipe 2 and the expansion and contraction of each of the flexible joints 5 due to the difference in expansion resulting from the variation of temperature during the operation of the condenser are not obstructed. Accordingly, it is possible to prevent the flexible joints 5, the pipe plate 3 and the cooling pipe 2 from being damaged.

摘要： PURPOSE: To provide a condenser wherein the concentration of oxygen in the condensate which is deaerated in the condenser in prevented from rising and the period required for starting a steam turbine plant can be shortened, by introducing steam present outside a steam turbine between a ceiling plate of a hot well and the liquid level of the condensate stream so that the steam is caused to flow in a condensate flowing passage and to cover part of the surface of the condensate.
CONSTITUTION: Dripping condensate 5 is allowed to drip onto an upper ceiling plate 9 and the hot well ceiling plate 7, and flows as a condensate thin film stream 30 on the hot well ceiling plate 7 into the hot well 8 where it is stored as condensate 6. Between the flowing surface of the condensate 6 and the hot well ceiling plate 7 is introduced steam from outside. An auxiliary steam pipe 21 is provided and extended via a scavenging auxiliary steam valve 27 to the space 11 over the condensate. Auxiliary steam 29 introduced into the space 11 over the condensate flows in a direction opposite to the flowing direction of the condensate flow 31, and further flows to cover the surface of the condensate thin film stream 30 so that the gas having a high oxygen concentration is swept. Thus, old non-deaerated water would not dwell in the hot well 3 for a long time so that there is no possibility that oxygen is redissolved into the fresh deaerated water.
