PROBLEM TO BE SOLVED: To provide a support structure of a heat transfer tube panel which can prolong the life of the heat transfer tube support by decreasing a thermal stress (temperature difference) generated at a heat transfer tube and the heat transfer tube support on the rear flow side of a duct burner, especially the thermal stress (temperature difference) at a welded part. SOLUTION: In this support structure, between adjacent vibration proof supports 22, 23; 25, 26; 28, 29 made of a honeycomb structure for welding and fixing each of the heat transfer tubes 31, arranged with their longitudinal direction crossing the pipe axis direction of the heat transfer tube 31 in a gas passage and bundling a plurality of the heat transfer tubes 31, plate-state supports 21, 24; 27, 30 are arranged in a space where the heat transfer tube 31 is not arranged, and the vibration proof supports 22, 23; 25, 26; 28, 29 corresponding to a portion of a gap between the vibration proof support and the heat transfer tube 31 are welded and connected to contact portions 32a and 32b of the plate- state supports 21, 24; 27, 30.
