摘要： A condenser (4) best suitable for a steam turbine (3) expels the oxygen-containing gas residing in the condensate passage (11) in the hot well part (10) thereof by means of a scavenging steam. The oxygen-containing gas is expelled by scavenging gas, which is introduced into the atmosphere of the condensate passage (11) and arranged to flow counter to the condensate flow. The scavenging means consists of a steam pipe (20) attached to the vicinity of the outlet (16) of the condensate passage (11) in the hot well part (10), and a valve device (21) provided in the intermediate portion of the steam pipe (20).

摘要： In an apparatus for deaerating condensate in a condenser (1) employed in a steam turbine plant, an open conduit (50a) to permit the condensate to flow to a covered conduit (50b) covered so that the condensate cannot flow therein without passing the open conduit (50a). The condensate is heated in the open conduit (50a), resulting in more effective and quick deaeration of the condensate and quick start up of the plant.

摘要： A horizontal feedwater heater for use in heat power stations, of the type having a shell (1), a plurality of U-bent heat transfer tubes (6) extended in the longitudinal direction of the shell and a vent tube (15) extended in the longitudinal direction of the shell substantially at the centre of the latter and adapted for extracting and discharging non-condensed gas. The feedwater heater has a baffle (20) arranged at each side of the vent tube and having a horizontal plate portion (20a) extended horizontally from the vent tube and an inclined plate portion (20b) inclined downwardly from the end of the horizontal plate portion at an obtuse angle to the latter. The length of projection of the baffle (20) from the vent tube (15) is varied along the length of the shell in accordance with the ratio of amount of heat exchanged between the steam and feedwater in each axial section of the tube nest (16) connected to the feedwater inlet (3) to the amount of heat exchanged between these fluids in the corresponding tube nest section of the feedwater outlet side (4), thereby to permit an efficient extraction of the non-condensed gas. The structural members contactable with the heating steam is made from a low alloy steel containing more than 1 % of Cr to exhibit a high corrosion resistance.
