Abstract

998,502. Forced flow steam boilers. COMBUSTION ENGINEERING Inc. Nov. 11, 1963 [Dec. 28, 1962], No. 44361/63. Heading F4A. A high temperature shell and tube vapour generator having a relatively thick tube sheet designed to keep the thermal stresses within reasonable limits by mounting the hottest tube ends in an offset of the tube sheet, consists of a substantially closed cylindrical shell 12 having a domed head 14 and divided by a tube sheet 16 into a vapour-generating portion 18 and a head portion 20. Bundles of U-tubes 22, 24, 26 forming economizer, evaporator and superheater sections, having their inlet and outlet ends mounted in tube seats 28 in the tube sheet, extend into the vapour generating portion containing tube bundle compartments formed by imperforate and perforate baffle plates 64, 66 which serve to direct the heating fluid in series flow from the inlet nozzle 60 over the superheater, evaporator and economizer tubes, through an annular passage 72 formed by a baffle 70 thereby cooling the shell wall to an outlet nozzle 62, the ends of the tube bundle compartments are closed by baffle plates 68, 69. The head portion is divided into a number of compartments by baffles interconnected through nozzles and external pipes (not shown) such that heated fluid is passed in series through the tube bundles. The outlet ends of the superheater tubes are mounted in a circular offset section 74 connected by a relatively thin-walled cylindrical transmission member 76 to the remainder of the tube plate and the superheated vapour is exhausted through a dome-shaped cap 90, a bellows 96 and a nozzle 58 having an insulating sleeve 101. The member 76 is enclosed by insulating members 78, 82, the latter extending over the cap 90. Access to the tubes is provided by a manhole 104 in the head 14 and openings in the baffles within the head.
