GAS TURBINE WITH TWO SWIRL SUPPLY LINES FOR COOLING THE ROTOR
A gas turbine has at least one rotor and inner housing part to form an annular chamber therebetween. The annular chamber is fluidically connected to a compressor portion at one end and expansion turbine portion at the other, and is supplied with cooling fluid. First and second swirl supply lines sup...

| description | A gas turbine has at least one rotor and inner housing part to form an annular chamber therebetween. The annular chamber is fluidically connected to a compressor portion at one end and expansion turbine portion at the other, and is supplied with cooling fluid. First and second swirl supply lines supply the annular chamber with cooling fluid. The cooling fluid is supplied to the surface of the rotor with a tangential flow component, and a first seal element in the annular chamber acts as a flow resistor. A discharge line in the rotor between the first seal element and expansion turbine portion receives and discharges cooling fluid from the second swirl supply line. No bypass lines are provided from the first swirl supply line such that the cooling fluid is conducted around the second swirl supply line in order to be returned to a location of the annular chamber. |
