A condenser includes a high pressure side condenser, a high pressure side cooling tube bank, a high pressure side hot well, a low pressure side condenser, a low pressure side cooling tube bank, a pressure shroud provided inside the low pressure side condenser, a low pressure side hot well, high pressure steam introducing portion, low pressure side condensate introducing portion, a flash box which communicates with at least one of the high pressure side hot well and the low pressure side hot well, flashes a heater drain from a feed water heater, and urges at least one of the high pressure side hot well and the low pressure side hot well to recover the flashed heater drain, and a flash steam path which introduces flash steam generated inside the flash box into at least one of the high pressure side hot well and the low pressure side hot well.

Condenser

An active sensoris positioned on an outside of a pipeso as to detect a thickness of the pipe. The active sensor comprises: an oscillatorcapable of inputting oscillatory waves into the pipe and sweeping a frequency of the oscillatory waves within a desired range; and an optical fiber sensor mounted on the pipe, the optical fiber sensor detecting the oscillatory waves generated in the pipe.

Active sensor, multipoint active sensor, method for diagnosing deterioration of pipe, and apparatus for diagnosing deterioration of pipe, and apparatus for diagnosis deterioration of pipe

Vertical sectional shapes of portions in which condenser tubes of the upper tube bundleand the lower tube bundleare arranged, in vertical sections of the upper tube bundleand the lower tube bundle, are formed to be approximately U-shapes, and a noncondensing air ejection ductis provided to be positioned on a central joint portion of the U-shape of the upper tube portionin an upstream side where circulating water flows first. At a portion in which the condenser tubes are not arranged between the upper and lower tube bundles, steam flow prevention platesare provided to be positioned at both right and left sides of the noncondensing air ejection duct

A heat transfer promoter composition comprises a triazine-dithiol derivative represented by the general formula ##STR1## wherein R represents --NHR' or --NR'.sub.2 wherein: R' is a hydrocarbon group; M is selected from the group consisting of hydrogen, alkali metals, and alkaline earth metals; and at least one of M groups is alkaline metal or alkaline earth metal. This heat transfer promotor is applied to that surface of a condenser tube to be contacted by a vapor to be condensed.

A reheater for a steam power plant generally comprises a tube plate, a header including a high-temperature chamber and a low-temperature chamber defined outwardly of the tube plate, and a number of heat-exchanger tubes bent into U-shapes, both ends of which are secured to the tube plate. The reheater further comprises nozzle members, each having a flange portion, inserted into the upstream ends of the heat-exchanger tubes, respectively, and a bellmouth plate having a number of holes, secured detachably to the tube plate such that the holes align with the nozzle members. The flange portions of the nozzle members are secured firmly between the bellmouth plate and the tube plate.
