Abstract

A condenser includes: a vessel (11) configured to receive a steam flow (S) in a first horizontal direction (X); and cooling tube groups (21, 22, 23, 24) elongated in the first horizontal direction (X) inside the vessel. Each of the cooling tubes groups has a plurality of cooling tubes (31) that are disposed in parallel and extend in a second horizontal direction (Y), which intersects with the first horizontal direction. A hollow portion (32) is formed in the first horizontal direction (X) inside each of the cooling tube groups. A non-condensed gas discharge unit (33) is arranged in the second horizontal direction (Y) at a downstream side of each of the cooling tube groups and includes an opening portion (34) on the hollow portion side. Each of the cooling tube groups includes a partition member (35) extending from the non-condensed gas discharge unit and open at the hollow portion.

Dependent claims

A condenser including:

a vessel configured to receive a flow of steam in a first direction;
a cooling tube group having an interior hollow portion and disposed inside the vessel, the cooling tube group having a length extending in the first direction, the cooling tube group being formed by arranging a plurality of cooling tubes in a second direction which is orthogonal to the first direction;
a non-condensed gas discharge unit provided at a downstream end portion of the cooling tube group along the first direction, wherein the non-condensed gas discharge unit is elongated in the second direction and includes an opening directed toward the hollow portion;
and
a partition member extending from an open side of the non-condensed gas discharge unit toward the hollow portion,
wherein the partition member includes:
an upper partition plate having a first end connected to an upper portion of the non-condensed gas discharge unit and a lower partition plate having a first end connected to a lower portion of the non-condensed gas discharge unit,
wherein the upper partition plate and the lower partition plate have respective second ends positioned at a downstream end of the hollow portion,
wherein an upper gas flow passage is provided along an upper surface of the upper partition plate, a lower gas flow passage is provided along a lower surface of the lower partition plate, and the upper gas flow passage and the lower gas flow passage are in fluid communication with the hollow portion, and
wherein the upper partition plate and the lower partition plate have an upper guide portion and a lower guide portion, respectively, and the upper guide portion is inclined downwardly and the lower guide portion is inclined upwardly.
