  • Piping support of gas turbine steam cooled combustor
    Patent number: 6523352
    Abstract: Piping support of a gas turbine steam cooled combustor is improved such that even when the piping support is damaged by combustion vibration, dropping of the piping support from the piping is prevented, so as to avoid intrusion of fractions of the piping support into turbine portion. An outer fitting member is fixed to a wall surface of a tail tube by welds. A ring is pinched inside the outer fitting member to be fixed by welds. The ring having an inner diameter slightly larger than an outer diameter of steam piping is fitted around the steam piping to be fixed by welds at three places. The steam piping is fixed to the ring, the ring is fixed to the outer fitting member and the outer fitting member is fixed to the tail tube. Thus, the steam piping is supported to the tail tube and even when the welds are detached by combustion vibration, no case of the outer fitting member dropping from the steam piping occurs.
