摘要： Piping support of gas turbine steam cooled combustor is improved such that even when the piping support is damaged by combustion vibration, dropping thereof out of piping is prevented so as to avoid intrusion of fractions into turbine portion. Outer fitting member (11) is fixed to wall surface of tail tube (102) by welding 82, 83. Ring (12) is pinched inside the outer fitting member (11) to be fixed by welding (80). The ring (12) having inner diameter slightly larger than outer diameter of steam piping (101) is fitted in around the steam piping (101) to be fixed by welding (81) at three places. The steam piping (101) is fixed to the ring (12), the ring (12) is fixed to the outer fitting member (11) and the outer fitting member (11) is fixed to the tail tube (102), thus the steam piping (101) is supported to the tail tube (102) and even when the welding 82, 83 is detached by combustion vibration, there occurs no case of the outer fitting member (11) being dropped of the steam piping (101).
