Abstract
693,735. Water-tubs, steam boilers, superheaters. BABCOCK & WILCOX, Ltd. Sept. 17, 1951 [Sept. 25, 1950], No. 21800/51. Addition to 693,532, Classes 123 (ii) and 123 (iii) In a modification of the invention described in the parent Specification, superheated steam from the separate source is introduced by a pipe 30, Fig. 1, into the steam space of the boiler, e.g. the feed drum 1, after passage through an attemperator 38. The attemperator comprises a steam and water mixing vessel which is disposed above the normal water level in the drum 1, encloses suction and accelerating nozzles 39, 40, Fig. 2, and is provided with a suction pipe 41, the latter being connected by pipes 42, 45 respectively to the boiler economiser 20, 21 and to the lower water distributers 3, 14 or, alternatively, the intermediate collectors 5 of the steam-generating tubes 4, 15 lining the combustion chamber of the boiler. In normal operation a valve 43 in the pipe 42 is maintained closed.
