Abstract: This low-pressure condenser is provided with: a pressure bulkhead which partitions the inside of the container into an upper space and a lower space; a heat transfer tube which is arranged in the upper space; and a reheater which is arranged in the lower space and which, by means of high-temperature steam flowing from the outside into the lower space, heats water which condenses in the upper space and flows into the lower space. The reheater includes multiple partition members, a receiving plate which receives water flowing downward via the partition members, and a dam which is connected to the outer peripheral edge of the receiving plate. The lower ends of the multiple partition members are below the upper end of the dam.

Abstract: A moisture separator where a corrugated plate 43 is provided with a collecting plate 49 formed to cover a flat portion 74 and an upstream end of a slope portion disposed on a downstream side of the flat portion 74. The collecting plate 74 has an opening which opens to an upstream side in the direction of the wet steam flow S1. The collecting plate 49 is fixed to the slope portion at a base end. Between the collecting plate 49 and a body portion of the corrugated plate, a pocket section 47 and a drain duct section 48 are formed. The moisture contained in the wet steam S1 turns into droplets and enters the pocket section 47 and the drain duct section 48 from the opening of the collecting plate 49 and falls down the pocket section 47 and the drain duct section 48 respectively by gravity.

Abstract: There is provided a slewing bearing structure capable of maintaining favorable bearing performance by adjusting and changing rigidity thereof while minimizing the increase in the weight thereof for preventing distortion of a pressure pattern caused by structural deformation from unfavorably affecting the bearing performance. A slewing bearing of a rolling bearing, in which a rolling element is put between bearing rings and formed on an inner ring and an outer ring, has a slewing bearing structure in which a rigidity strengthening portion, at which rigidity of the inner ring and/or the outer ring is increased more than that at peripheral portions, is formed at a circumferential area where a bearing contact pressure is high.
