Definitions
- the present invention relates to a hot gas-carrying housing element for a hot gas-carrying housing, which can be arranged in particular in a gas turbine plant around a turbine rotor of the gas turbine plant around and serves to guide a hot gas to a turbine part of the gas turbine plant. Moreover, the present invention relates to a wave protection jacket of the hot gas-carrying housing, which is designed to surround the turbine rotor of the gas turbine plant. Finally, the present invention relates to the hot gas-carrying housing itself and a gas turbine plant with a hot gas-carrying housing.
- a gas turbine plant 1 essentially comprises one or more combustion chambers 3 (see Fig. 1), in which a fuel is burned, a turbine 5, the hot and pressurized combustion exhaust gases from the combustion chambers 3 are supplied and in the exhaust gases below Cooling and relaxation work and so put the turbine 5 in rotation, and a compressor 7, which is coupled to the turbine 5 via a shaft 15 and through which the necessary air for combustion is sucked and compressed to a higher pressure.
- FIG. 1 shows such a gas turbine plant in a schematic view, wherein Fig.1a show a horizontal and Fig. 1b shows a vertical section through the system. From these Silobrennhuntn 3 flow the combustion gases 2 in one Direction, which is substantially perpendicular to the axis of rotation A of the turbine 5. Between the outlet 18 of the silo combustion chambers and the turbine 5, a mixing housing 8 is arranged, which is followed by an inner housing 9 arranged in the interior of the gas turbine housing 2 on the turbine side.
- the inner housing 9 has the task to protect the surrounding components from heat and to redirect the emerging from the mixing housing 8 hot gases in the direction of the turbine.
- the combustion exhaust gases When exiting the inner housing 9, that is to say when entering the turbine 5 of the gas turbine plant 1, the combustion exhaust gases then flow essentially parallel to the axis of rotation A of the turbine shaft 12.
- Hot gas-carrying housing, and in particular the described inner housing in gas turbine plants with Silobrennhuntn represent thermally highly stressed components. For this reason, measures are taken for cooling the hot gas bearing surfaces of the housing. These measures include the cooling of the particularly stressed areas by means of a cooling fluid which flows along the outside of the walls of these areas in order to absorb and dissipate the heat transferred to the hot gas-conducting surfaces.
- the inner housing hub 101 surrounds a shaft protection jacket 115 (FIG. 7 a), which in turn surrounds the shaft 12.
- the housing interior facing surface 109, the inner housing hub 101, the guide and guide surface for the combustion gases 2 while the housing interior facing away from surface 104 of the inner housing hub 101 surrounds the wave protection casing 115.
- the inner housing hub 101 is fixed to the shaft protection casing 115 by means of an annular rib 103, which is arranged centrally in the axial direction and protrudes toward the wave protection casing 115.
- the shaft protection casing 115 itself is fastened to the gas turbine casing 2 and has a web 105 with an annular groove 106 arranged therein in which the annular rib 103 engages.
- Inner housing hub 101 and wave protection jacket 115 are installed together as a unit in the gas turbine plant.
- the web 105 has passage openings 107 through which the cooling fluid can flow (see Figures 7a and 7b).
- the rib 103 experiences less heating during operation of the hot gas-carrying housing than the material regions located closer to the hot gas-carrying surface 109 of the cylindrical inner housing hub 101. This leads to a so-called barrel tire effect, which leads to stresses in the material regions of the inner housing hub 101 which adjoin the rib 103. In particular, at the designated by the reference numeral 111 locations may therefore cause cracks in the material.
- the rib has been moved into the area of the turbine-side opening of the inner housing, so that it is located in a thermally less heavily loaded area of the inner housing.
- Another object of the present invention is to provide a wave protection jacket for a hot gas-carrying housing of a Gas turbine plant to provide, which allows improved fixing of a hot gas-carrying housing element.
- Yet another object of the present invention is to provide an improved housing unit for a gas turbine plant.
- the first object is achieved by a hot gas-conducting housing element according to claim 1, the second object by a wave protection jacket according to claim 8, the third object by a housing unit according to claim 9 and the fourth object by a gas turbine plant according to claim 11.
