ABSTRACT:
An improved convection section assembly for process heaters comprising a plurality of horizontally-disposed heat transfer segments disposed in vertical array and supported by means attached externally to said assembly, said segments further comprising a plurality of tube sheets also supported by fixed external means. The use of such external support means enables the convection section assembly to be of unlimited width--which thereby permits the substitution of a large number of parallel heating coils for the conventional serpentine heating coil customarily used--and also enables the plurality of tube sheets to expand laterally. Thus, with only external refractory lined supports, there is no practical limit on the flue gas temperature that can be used.
