1. A pipe support structure that supports a pipe including a header pipe which extends in a first direction in a cross section of a duct and in which an inlet, into which a high-temperature fluid flows, is formed, and a plurality of nozzle pipes that are provided integrally with the header pipe, wherein the plurality of nozzle pipes extend in a second direction orthogonal to the first direction, and are arranged at intervals in the first direction, the pipe support structure comprising:
a projecting portion that projects from at least one surface in a third direction orthogonal to the first direction and the second direction in an outer peripheral surface of at least one of the plurality of nozzle pipes; and
a support member which is fixed to the duct and in which a guide groove, to which the projecting portion is fitted and which guides the projecting portion in a thermal elongation direction of the header pipe and the at least one of the plurality of nozzle pipes, is formed.
