Abstract

991,911. Water tube steam boilers; super-heaters. FOSTER WHEELER Ltd. Dec. 11, 1962 [Dec. 11, 1961], No. 44241/61. Heading F4A. A steam generator comprises an upright cylindrical shell 10 through which heating fluid e.g. the coolant from a nuclear reactor, circulates, the shell containing a coaxial downcomer 16 leading from a steam and water drum 18 which surmounts the shell 10. Steam generating riser tubes are distributed across the space within the shell, each riser tube consisting of an inlet tube 20, an outlet tube 22 and a cluster of tubes 24 therebetween attached to circular or polygonal headers. The headers are preferably hexagonal with nineteen tubes to a cluster, the hexagonal shape contributing to uniform distribution of the tubes across the shell. The inlet tubes 20 are attached to the lower end of the downcomer while the outlet tubes 22 discharge into an annular collecting riser 26 which surrounds the downcomer, passes through the upper end of the shell and thus leads the steam and water mixture into the steam and water drum 18. The latter contains steam separating and drying means 38, 40 and has a baffle 46 which defines with the shell of the drum and passageway 48 for dried steam leading to a further annular passageway 50 formed within the collecting riser 26. Superheating tubes 44 which are of similar form to and surround the steam generating tubes, receive steam from the passage 50 and deliver to an extension 54 of the lower end of the downcomer forming a final steam outlet. The latter passes freely through the lower end of the shell, a bellows 58 making the necessary seal. To ensure uniform distribution of the tubes across the shell the individual tubes may be sprung apart by taper keys 62 inserted in spacer plates 60, Fig. 4, as described in detail in Specification 991,915, and the headers may be staggered slightly in the vertical direction to allow for easy throughflow of the heating medium. Specifications 991,912 and 991,913 also are referred to.
