Title: Improvements in tubulous vapour generators
Inventor: ZOLLER RONALD ERNEST
IPC: F22B37/10
Filed: 1960-05-02
Abstract: 980,423. Water-tube steam boilers. BABCOCK & WILCOX Ltd. May 2, 1961 [May 2, 1960], No. 15405/60. Heading F4A. A water-tube boiler has a hopper bottom furnace chamber of width exceeding, for example, 100 feet, the chamber having walls lined with upright steam-generating tubes which extend downwardly to line the hopper bottom, the tubes being supplied with water from an elevated steam and water drum which extends horizontally and parallel to the front and rear walls of the furnace through a series of downcomers distributed along the drum and extending downwardly adjacent one of the said walls. The lower ends of the downcomers are connected to the steam-generating tubes lining the said one wall and the subjacent hopper wall and, by tubes extending across the hopper adjacent to and above the bottom thereof to the space outside the hopper remote from the downcomer tubes, to the generating tubes lining the opposite wall and subjacent hopper wall, whereby large longitudinal flows of water in the drum are avoided. The connecting tubes passing through the hopper may also serve to support the hopper bottom. In the form shown the generator has a top-supported furnace 1 of width between side walls 4 of 120 feet and depth between the front wall 2 and rear wall 3 of 30 feet. The furnace is fired by burners 5, the hot gases discharging through a lateral pass 6 containing superheater sections 7, 11. The furnace front and rear walls are lined with generating tubes 12, 15 which, together with the side wall lining tubes 31, discharge into a drum 35 mounted above and extending the length of the wall 2. A series of downcomers A ... L convey water to the lower headers supplying the generating tubes. Thus, as shown in Fig. 6, the lower ends 71 of the downcomers are connected to a header 13 supplying the tubes 41 lining the front wall of the hopper bottom 40 and the tubes 12 and by groups of tubes such as 76 to a header 16 supplying tubes 42 lining the rear wall of the hopper bottom and the tubes 15. The tube groups such as 76 are in the form of vertical platens and pass through the walls defining the slag outlet 43 from the hopper 40, the platens being suspended on tubes 12a, 15a and forming beams on which inclined buckstays 51, 59 supporting the hopper walls rest. In a modification, Figs. 9 and 10 (not shown), spaced bands of tubes lining the rear hopper wall are taken forwardly across the slag outlet to form spaces of inverted V-shape through which pass lateral extensions of the downcomers conveying water therefrom to the rear wall distribution headers. The front rear and side wall distribution headers may be internally divided by baffles so that the water flowing from the drum at any location through a downcomer tube is returned as steam-water mixture to the same location, thus avoiding large longitudinal flows of water within the drum.
