[Class 123 (iii)] In steam boilers comprising a superheater 4 in a first gas pass above a combustion chamber 1, a second pass 5 containing a water-tube bank 6, and one or more superheater bye-passes 13 all the tubes in which have a part of their length invariably traversed by gases, the bye-passes are contained wholly between the boundaries of pass 5 and traversed by part only of each of a proportion of the tubes in the pass, and the dampers 14 are disposed at the outlet end. Instead of the central arrangement shown with a partition 13a between the bye-passes, one may be located at each side wall of the boiler. Each bye-pass is defined by tiles or baffle walls 15, 15a, and the baffles 8, 9 of the second pass, and includes an inner baffle 16 to extend the effective length of the passage from inlet 17 to outlet 18</p> |
