<p>PROBLEM TO BE SOLVED: To provide a heat transfer pipe support structure of a boiler capable of suppressing abrasion with vibration generated between pipe bundle support members adjacent in an exhaust gas circulation direction and capable of continuing stable operation for a long time, and an exhaust heat recovery boiler including the heat transfer pipe support structure.SOLUTION: A rod 8 extending in an exhaust gas circulation direction is penetrated between both width end parts of pipe bundle support members 5, 7; both end parts of the rod 8 are fixed to the pipe bundle support members 5, 7; and a vertical clearance absorbing elongation difference of heat transfer pipes 2b, 3b, 4b among a tertiary superheater 2, a reheater 3 and reheater 4 as a heat transfer unit is formed in a portion where a rod 8 of the pipe bundle support members 5, 7 at a plurality of adjacent places of the transfer unit, that is an adjacent place between the tertiary superheater 2 and the reheater 3 and an adjacent place between the reheater 3 and the reheater 4, is penetrated.</p> |
