摘要： Piping support of gas turbine steam cooled combustor is improved such that, even when the piping support is damaged by combustion vibration, piping is prevented from dropping so as to avoid the occurrence of fractions thereof from entering into the turbine portion. An outer fitting member (11) is fixed to the wall surface of a tail tube (102) by welding (82, 83). A ring (12) is pinched inside the outer fitting member (11) to be fixed by welding (80). The ring (12), having an inner diameter slightly larger than the outer diameter of the 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), such that the steam piping (101) is supported to the tail tube (102). Thus, even when the welding (82, 83) is detached by combustion vibration, the outer fitting member (11) remains fixed to the steam piping (101).

摘要： PROBLEM TO BE SOLVED: To prevent a support component from entering gas turbine part by preventing the support component from disengaging from a pipe when a support is damaged by a combustion vibration. SOLUTION: An outer side attaching member 11 is fixed to a wall surface of a tail wall 102 by welds 82, 83, a ring 12 is put inside the tail wall 102, and the attaching member 11 and the ring 12 are fixed to both side by a weld 80. The ring 12 has a diameter somewhat larger than that of a steam pipe 101 and inserted to the pipe 101, and an outer periphery of the pipe 101 and an inner periphery of the ring 12 are fixed to each other by weld 81 at three points. As a result, since the pipe 101 is fixed to the ring 12, the ring 12 is fixed to the outer side attaching member 11, and the outer side attaching member 11 is fixed to the wall surface of the tail wall 102, the pipe 101 is supported by the attaching member 11. Further, even if the welds 82 and 83 are disengaged due to vibration or the like, since the attaching member 11 is fixed to the ring 12, the attaching member 11 is prevented from falling from the pipe 101.

摘要： PROBLEM TO BE SOLVED: To provide a snow-attach preventing apparatus for a suction filter of gas turbine capable of preventing filter from being clogged with snow by removing the snow inflowing from the suction port at the front face, so as not to make attachment to the filter. SOLUTION: A house 10 for a gas turbine is furnished with a suction port 17 to suck the air 30, and water drops and snow are removed from a room 24 by a demister 1, and the air removed of dust by a filter 16 flows to a duct inlet 23 from a room 25 and is led to the gas turbine. A water-sprinkling nozzle for sprinkling water in summer, etc., is installed at the inlet of the suction port 17, while another 7 for sprinkle water to the snow inflowing in winter is installed at the entrance to the room 24. The demister 1 is installed on the front face of the filter 16, to remove also permeating water drops, rainwater, and snow. The demister 1 is formed with an eliminator, a water louver, or a wire pad, and the inflowing snow is allowed to contain water using the nozzle 7, while the snow attached to the demister 1 is dropped off by the weight of the water contained, and will not attach to the filter 16. The differential pressure between inside and outside the filter 16 will not rise either.
