Definitions
- the invention relates to a gas turbine with a compressor for air flowing in a variety of fluidic parallel switched combustion chambers is heated before going over a transfer channel flows to a gas passage in a turbine.
- FIGS to 7 The subject of said US-PS 4,719,748 is shown in FIGS to 7 and the associated description, however, also one consuming cooling device in which a combustion chamber and a from this leading to a turbine connecting channel a second wall is covered against the flow of compressed air are.
- this second wall are a variety of Provided openings through which the compressed air targeted is directed to the wall sections to be cooled.
- the invention is based on the object, for a gas turbine of the type mentioned above to provide an arrangement in the one unavoidable pressure loss in the stream of compressed Air is further reduced.
- compressed Air leaves it through a ring of vanes 4 and flows in the direction of the arrows 5 first by an annular in cross section paraxial Channel section 6 of an air duct, the inside through a Wall 38 and outwardly bounded by a wall 39.
- the webs 7 carry an annular cross-section C-shaped deflector 8 and are via webs 7 in the end anchored the channel section 6.
- One in the end of the canal section 6 lying leg 9 of the cross section of the deflector 8 forms with its upstream edge 9 one to one to the axis 1 concentric circle curved wavy line 37.
- the wall thickness of the deflector 8 increases, starting from the edge 9 bis to its center, strong too and is also in the circumferential direction of the Deflector 8 not constant, but waving and decreasing.
- a radially outside Cross-section legs of the deflector 8 is substantially adapted to the contour of the combustion chambers and forms with its free end a wavy edge 35th This Outside cross-sectional leg of the deflector 8 is beyond also wavy in shape, with the thus formed Waves opposite the waves of the wavy line 37 in opposite directions are, as best seen in Fig. 3 can be seen.
- the special shape of the deflector 8 with in its circumferential direction Waves 35 and 37 forming legs of his C-shaped Cross section forces a division in its area of the air flow in a partial flow 5a to the top of the Combustion chambers 10 and in a partial flow 5b to the bottom of the Combustion chambers 10. This is the top of the combustion chambers 10, relative to the gas turbine, radially outward and correspondingly the bottom radially inward.
- the routes of the partial flows 5a and 5b are about the same size, so that all parts of the cooling air from the compressor 3 to the entry into the combustion chambers 10th to travel the same distance.
- Each of the combustion chambers 10 is supported by webs 11 from the inside on an outer casing 12, which at the same time the outer wall an air passage 20 and a continuation of the air duct 6 represents the air flowing in the direction of the arrows 5.
- the envelope 12 carries at its outer free end a cap 13 through which the air enters the interior of the combustion chamber 10 is guided.
- the combustion chambers 10 are so close together in the circumferential direction arranged that the outer sheaths 12 at their end facing the runner 1 penetrate each other would.
- To the combustion chambers 10 together with their outer sheaths 12 still as far as desired in the direction of the To be able to push runners 1 are at the outer claddings 12 recesses 40 (Fig. 4) provided in the area adjacent Combustion chambers 10 between them a common Air duct 20 have.
- the interior of the combustion chambers 10 is also by a not shown nozzle fuel, such as a combustible Supplied with gas or atomised liquid fuel, by the combustion of the air in the combustion chamber 10 to a hot gas 34 is baked out.
- nozzle fuel such as a combustible Supplied with gas or atomised liquid fuel
- the combustion chamber 10 and the outer casing 12 holding it are mounted in a socket 14 in a housing shell 15 and one fixed to the outer sheath 12 Fixed flange 16 on the outer end of the nozzle 14.
- One inner end 36 of the combustion chamber 10 is sealed in one
- Kunleitkanal 17 the output of the combustion chamber 10 with a in cross-section annular gas channel 18 in one Turbine connects.
- hot gas 34 is a Variety of, for example, 10 to 30 combustion chambers 10 evenly distributed on the circumference of the turbine plant and are their Junctions in the transfer channel 17 by a in the direction on the gas channel 18 open peripheral channel 19 with each other connected.
- the transfer channel 17 is connected by thin webs 21 anchored a guide member 22 of the turbine.
- the guide member 22 and a guide member 23 are in a housing shell 24 stored and are by securing blocks 25 against Rotation secured.
- the guiding parts 22 and 23 for example, by hydraulic or pneumatic Motors 26 axially parallel over small distances, wherein a flange 27 is elastically deformed and with in it stored deformation energy for the return of the Leiters 22 or 23 is used.
- One of the housing shells 15 and 24 enclosed volume is divided by partitions 28 into chambers.
- the guide parts 22 and 23 have a funnel-like shape and carry on their inside in guide rings 29 fixed vanes 30, whose guide rings 29 opposite ends are firmly connected together by rings 31. Between each other adjacent wreaths of vanes 30 is ever one Wreath provided on the rotor 1 wedged blades 32, whose free tips guide rings 33 are opposite. there the guide rings 29 and 33 form an outer and the rings 31, together with feet of the blades 32, an inner boundary the gas channel 18 for the hot gas 34 in the turbine.
