MIXING SCREW FOR A FUEL INJECTOR IN A COMBUSTION CHAMBER OF A GAS TURBINE, AND CORRESPONDING COMBUSTION DEVICE |
摘要 |
In a fuel injection device at a base of a combustion chamber, a mixing air inlet screw is manufactured with its peripheral holes extending only over a sector of a circle directed towards the air's propagation cone, wherein the remainder of the periphery of the screw is closed. It is then possible to reduce load loss of the injection system while obtaining an improved quality of the mix supplied to the chamber. Such a device can be used in gas turbines fitted with centrifugal compressors and in which the air flow towards the combustion chamber must therefore be made convergent. |
