Abstract

1,129,076. Fluid heaters. FOSTER WHEELER CORP. 28 April, 1966 [11 June, 1965], No. 18729/66. Headings F4A and F4S. A process fluid heater has rows of vertical tubes 41 extending through an enclosure 21 into which burners 31 fire, the gases from the enclosure 21 then passing over convection heated tubes 27. The tubes 41 are supported by a weight and pulley arrangement 49 from frame 53, and are supplied with fluid from upper header 50 through connectors 58, 60. The tubes 41 are provided with removable end caps 47, through which catalyst (54, Fig. 5) and catalyst support cones (51) may be inserted. From the tubes 41, the fluid passes through connectors 55 to a horizontally extending lower collector header 42, which is mounted in a support casting 44 by a bracket and slot arrangement (48, 46, Fig. 2) to permit longitudinal expansion of the header. A metal bar 61, having expansion rate similar to that of the header 42 is placed parallel thereto in contact with and between the tubes 41, a little above the point of connection of the connectors 55 to the tubes. This expands as the header does, thereby bowing out the tubes 41 at their lower end, and preventing the connectors 55 from breaking. The bar is formed from a plurality of half sections 63, Fig. 3, each section engaging four of the tubes, the sections being bolted together at their edges. The sections associated with each row of tubes, are cross linked by members 73, to form the bar 61 which is maintained in place by spaced lugs (77, Fig. 2) on the tubes. In a modification (Figs. 5 to 8) provided with a single row of vertical tubes, the bar (61) is formed from two overlapping half bar sections (81).
