Abstract: The present disclosure relates to a wall tube hanger support (15) in a fired heater (100), supported through the radiant section casing (8), supporting a set of radiant tubes (12) positioned adjacent to the radiant section casing (8). The wall tube hanger support (15) comprises a tube supporting portion (15a) configured to support the set of radiant tubes (12) and a wall mounting portion (15b) secured inside a refractory lining (10) of the radiant section casing (8) through a first set of bolts (31) and a first set of nuts (30). The radiant section casing is provided with a second set of nuts (32a, 32b) welded thereon from an outside of the fired heater and a second set of bolt (34a, 34b) is adapted to pass through the second set of nuts and the radiant section casing for lifting the lower end of the wall tube hanger support from outside.
