Abstract
616,445. Water chambers in steam boiler fireboxes. BULLEID, O. V. Sept. 2, 1946, No. 26402. [Class 123(ii)] In a locomotive boiler comprising a barrel 3 and a firebox 1, the roof of the latter is constituted by a plurality of steam and water drums e.g. a large diameter central drum 14 and a pair of smaller side drums 15, these drums extending longitudinally from the barrel so as to be spaced apart across the width of the firebox and each being connected to the lower rear end of the barrel 3 by flat water chambers or siphons 4, a common transverse header 16, to which a feedwater supply pipe 18 may be connected, and two short vertical ducts 17. Each chamber 4 tapers downwardly and opens at its downwardly and forwardly swept lower edge into a tubular duct 5 jointed to the header 16, and the firebox may be fitted with a firebrick wall 20 which extends from the fire-grate support to the ducts 5 and is continued as a rearwardly and upwardly sloping partition or arch 21. The boiler is of welded construction throughout, with the drums 14, 15 reinforced by longitudinal stay rods 19. In a modification a single steam-and-water chamber extends over the entire roof of the firebox, and the ducts 5 of the transversely-spaced chambers or siphons communicate directly with the bottom of the barrel 3 at points spaced longitudinally and circumferentially of the latter.
