    • A condensation system for use in a power plant including a steam generator and steam turbine comprises at least one side stream condenser. The side stream condenser defines therein first and second hot wells with the first hot well receiving therein condensate produced by condensing steam exhausted from the steam turbine. A condensate pump device forcibly delivers the condensate through a condensate feed line having one end thereof connected to the first hot well and the other end communicating with the second hot well. A first purification device is provided in the condensate feed line to remove impurities from the condensate flowing therethrough. A main condensate pump device forcibly delivers the condensate through a main condensate feed line having one end thereof communicating with the condensate feed line and the other end connected to the steam generator. A second purification device is provided in the main condensate feed line downstream of the main condensate pump device, for removing impurities from the condensate introduced into the steam generator through the main condensate feed line.

    • A side stream type condenser which has a first hot well for condensing steam exhausted from a turbine and storing the condensed water and a second hot well for storing the purified condensed water to prepare for water feed to a main system includes a partition plate for defining the two hot wells. The partition plate is formed with a weir portion so that part of the condensed water in the second hot well may overflow to keep a fixed water level. The weir portion is constructed in the shape of a labyrinth and is formed with a passage normally filled up with the condensed water, and a space in the upper part of the second hot well communicates with the upper space of the first hot well through this passage only. The condensed water in the first hot well is fed to a purifying system disposed outside, and is purified therein. It is thereafter fed to the second hot well when the main system requires the feed water and to the first hot well when not, through pipe means constructed so as to feed the water selectively to the first hot well and the second hot well. The water level of the first hot well is controlled by causing the condensed water to overflow from the weir portion. On the other hand, the water level of the second hot well is controlled in such a way that the actual water level is detected by a water level gauge disposed in the second hot well, that the quantities of water in an inlet and outlet of a tank for storing the feed water of the main system are controlled in accordance with the detected water level, and that the feed water of the tank is caused to flow into the first hot well.

    • A sliding bearing such as a half sliding bearing, a cylindrical bushing and etc. includes a back metal of a three-layer construction composed of a back metal portion of austenitic stainless steel having a thermal expansion coefficient of not less than 15.times.10.sup.-6 /.degree.C., a plated bonding layer formed on the back metal portion, and a plating layer of Cu or a Cu alloy formed on the bonding layer. An alloy layer made of a copper-lead alloy or a lead-bronze alloy is formed on the back metal. With this construction, the alloy layer is positively bonded to the back metal. The austenitic stainless steel is of such a type that the back metal is less subjected to work hardening, and the austenitic stainless steel contains those components which prevent work-inducing martensite transformation.
