    • PROBLEM TO BE SOLVED: To provide a steam condenser capable of smoothly guiding steam in a tube group to a gas cooling part without retainment by suppressing a pressure loss of the steam.
      SOLUTION: A steam condenser which condenses steam exhausted from a steam turbine. Heat transfer tubes are arrayed below the steam turbine inside the container. Cooling medium flows inside the heat transfer tubes. The heat transfer tubes extend horizontally, and include at least two upper heat transfer tube groups and at least two lower heat transfer tube groups arranged with a gap between each other. Each heat transfer tube group is constituted by arraying heat transfer tubes like a grid. At a lower part between the lower heat transfer tube groups, a baffle plate which obstructs flow of steam extends horizontally. Between the upper and lower heat transfer tube groups, inter-tube-group inundation prevention plates extend horizontally. In each heat transfer tube group, an enclosure part extends to guide gas from the enclosure part to outside of the container through a gas extraction duct.

    • PURPOSE:To obtain an exhaust heat recovery heat exchanger meeting requirements by a turbine by dividing a superheater into a primary superheater and a secondary superheater, placing the secondary superheater on the upstream side and the primary superheater on the downstream side and further setting a reheater between the secondary and the primary superheaters. CONSTITUTION:Feed water is sent to an economizer 16 by a feed water pump 18 and superheated by exhaust gas. Superheated feed water is sent to a steam drum 17, superheated by exhaust gas through an evaporator 15, becomes gas and water mixture fluid and enters the steam drum 17 again. The gas and water mixture fluid is separated into steam water in the steam drum 17 and the steam is superheated by exhaust gas in a primary superheater 14. The superheated steam is superheated further, becomes the prescribed steam condition and supplied to a steam turbine. Further, the steam after it has worked in the steam turbine is introduced in the reheater 13 to reheat, but, since the reheater 13 is placed between the secondary superheater 12 and the primary superheater 14, the steam can obtain the prescribed temperature.

    • PURPOSE:To uniformly maintain a space required for the winding even with a small winding slot by forming a glass fluid regulating film made of a nonmagnetic film onto the surface of glass packed in advance in each slot of the bonding face side of a couple of magnetic bases and onto the surface of the winding slot not coated with glass. CONSTITUTION:Heat treatment is applied to magnetic bases 1, 2, glass 11 is packed respectively to glass packing slots 4a, 4b, a winding slot 3 and a track width regulating slot 5 respectively and excess glass adhered to the surrounding of the slots 3, 4, 5 is removed. Part of the packed glass 11 is removed and an air gap slot is formed, the glass fluidity regulating film 14 is formed to the surface to regulate the fluidity of the glass 11 at re-melting. Thus, the quantity of the packed glass 11 is minimized as required. Thus, even when the depth and width of the winding slot 3 are small, the space required for winding an exciting coil is ensured uniformly by using the glass fluidity regulating film 14.
