Abstract

1307846 Tube supports FOSTER WHEELER Ltd 26 May 1970 [6 June 1969] 28749/69 Headings F4A and F4S A support 60 in a heater comprises clamping bars 62 pivotably connected together near their ends to form a zig-zag lattice, having the tubes 28, 30 held by the bars between the crests of the lattice, so that longitudinal expansion of the tubes is allowable but distortion of any tube away from the axial position causes the lattice to grip nearby tubes to limit the distortion. The support may have members 68 provided at its ends to grip the end tubes, said members being connected via links 70 to the walls 72 of the heater, and supported on members (66), Fig. 1 (not shown), fixed to the tubes. The support 60 may be used in a heater having four series connected rows of pipes (24, 26, 28, 30) the support 60 being fixed to the two ends of the furnace chamber (12).
