Definitions
- the present connection relates to a single-shaft, stationary gas turbine for power generation with a rotor welded and bladed from a plurality of disks, wherein cavities are present between the disks and in the rotor periphery between the rotor surface and platforms formed with cooling air fed by the rotor blades or heat exchanger segment plates.
- Gas turbines of this type are known, the cooling air being removed from the high-pressure part of the compressor in the known gas turbines.
- the object is achieved to provide improved cooling of the rotor in a gas turbine of the type mentioned.
- this is done by feeding the axial channels in the rotor periphery from the cavities between the rotor disks.
- the cavities are connected to the axial channels mentioned, preferably via connecting openings and are connected via a central, fed from the downstream end of the rotor cooling air supply duct.
- cooling air can be taken from the central part of the compressor, where it is still at a lower pressure and a lower temperature than at the compressor outlet.
- the resulting low-pressure cooling is more effective and also manages with a lower cooling air flow. The losses are also lower and the efficiency is thereby improved.
- the gas turbine shown in FIG. 1 has a compressor 1, a turbine 2, an exhaust gas housing 3 and an exhaust gas diffuser 4. 5 the combustion chamber and 6 the rotor.
- the rotor 6 is welded together from a plurality of disks in its axial direction, with cavities remaining between the individual disks.
- two disks are shown and designated 7 and 8 respectively.
- the structure of the cavities between the rotor disks can be seen in the enlarged detail in FIG. 2. That one
- the cavity shown between the rotor disks 7 and 8 is designated 9. It is narrow in its central area around the rotor axis 10 and widens outwards into a kind of annular chamber 11.
- the rotor 6 is provided along its axis 10 with a central channel 20 extending from the end face 19 of its downstream end. Through the central channel 20, the cavities 9 and the connection openings 18, the axial channel 17 in the rotor periphery is fed with cooling air.
- the cooling air is branched off in the central part of the compressor from the process air which has already been partially compressed there and is conducted via a line 21 to the end face 19 of the rotor end located downstream.
- the line 21 passes through hollow ribs 22 between the outer ring 23 and the inner ring 24 of the exhaust gas diffuser or housing 3, 4.
- the connecting openings 18 start in the cavities 9 on the very outside, ie where they have their greatest diameter or radial distance R1.
- the annular chambers 11 of the hollow spaces 9 taper beyond the radius R2 each also continuously. This ensures that dirt carried in the cooling air cannot collect in the cavities 9 but is thrown out through the connecting openings 18. In addition to thermal insulation effects due to deposited dirt, this also prevents the imbalance of the rotor caused by dirt accumulation.
- the weld seam 12 is arranged slightly offset axially with respect to the connection openings 18. Its root 25 therefore comes to lie at a radial distance R3 from the rotor axis 10 which is somewhat smaller than the radial distance R1 from which the connection openings 18 originate.
- the formation of pockets on both sides of the weld seam 12 on the outer zone of the cavities 9 in order to relieve the weld seam root 25, as was previously the case, is dispensed with for the aforementioned reasons of dirt ejection.
