摘要： PURPOSE:To contrive to enhance the condensation efficiency of tube nests by a structure wherein guide plates are installed in flow passages formed between a feed water heater and an upper shell. CONSTITUTION:A guide plate 20, which is parallel to a tube nest 8 and extends from the exhaust port 16 of a low pressure turbine toward the highest point of the tube nest 8, is formed in a flow passage 15 formed between a feed water heater 11 and an upper shell 10. The guide plate 20 is formed in a smooth curved surface so as not to disturb the vapor flow. Because the guide plate 20 is installed so as to extend from the exhaust port of the low pressure turbine toward the highest point of the tube nest 8, vapor is divided by the guide plate 20, resulting in turning the vapor in wo flows, which are symmetrical with respect to the guide plate 20, on the downstream side of the feed water heater or just before the highest point of the tube nest 8. Consequently, the exhaust vapor of the turbine causes no channeling within a condenser and flows in the tube nest 8 over the whole surface of the tube nest 8, resulting in bringing almost all cooling tubes into action with the vapor effectively and accordingly enabling to achieve the enhancement of the condensation efficiency of the tube nest.
摘要翻译：目的：旨在通过一种结构提高管巢的冷凝效率，其中导向板安装在供水加热器和上壳体之间形成的流动通道中。构成：平行于管座8并从低压涡轮机的排气口16朝向管座8的最高点延伸的引导板20形成在形成于给水加热器导向板20形成为平滑的弯曲表面，以便不会扰乱蒸气流。由于引导板20安装成从低压涡轮机的排气口朝向管座8的最高点延伸，所以蒸气被引导板20分开，从而使得流动中的蒸气转动，相对于引导板20对称，在供水热水器的下游侧，或恰好在管座8的最高点之前。因此，涡轮机的排气蒸气不会在冷凝器内引流，并流入管座在管座8的整个表面上，导致几乎所有冷却管与蒸汽有效地起作用，因此能够实现管巢的冷凝效率的提高。

摘要： PURPOSE:To suppress generation of vibrative force at the vanes of a mixed pressure type turbine created by the fluid, by furnishing a fluid control member, which functions also as a guide for the fluid, in a circumferential flow line formed in communication with secondary supply pipe of the turbine. CONSTITUTION:In communication to secondary supply pipe 3, a circumferential flow line 5 is formed to supply the fluid to the turbine passages 15 from the circumferential direction of the rotor 10, and in this line 5 a pair of fluid control member 16, 17 are furnished, which shall function also as a fluid guide. The rate of flow of the secondary flow is, after flowing into this circumferential flow line 5, is uniformalized in the circumferential direction of the flow line 5 by the control member 16, and the velocity energy will go out when the flow runs against the other control member 17. Thus fatigue breakage of the vanes 12, 13 owing to vibromotive force of the fluid can be well prevented.
