  • Patent number: 12215864
    Abstract: A combustion section of a gas turbine includes an annular combustion chamber, a burner arrangement upstream of the combustion chamber, an annular compressor diffusor, and an annular combustion casing. The combustion casing has an outer section wall, an upstream section wall, and an inner section wall. The inner section wall extends along the rotor axis and is arranged between the burner arrangement and the compressor diffusor. A shielding is attached to the inner section wall at the side facing the rotor axis with a free space in-between at least. An outer diffusor wall of the compressor diffusor extends in axial direction up to the upstream half of the shielding.

  • Patent number: 10138813
    Abstract: An oil bearing to support a rotor of a turbine, especially of a gas turbine, wherein the rotor extends along a rotor axis coinciding with a bearing axis, has at least one oil bearing pad being lubricated by oil, including an oil sump suitable and located to collect the oil from the bearing pads by forces of gravity, including a drain system of the oil sump to conduct the oil away from the oil sump. The drain system includes at least three drain openings of the oil sump, wherein a first drain opening joining a first drain line is located between 4 o'clock and 5 o'clock according to the bearing axis, wherein a second drain opening joining a second drain line is located between 5:30 and 6:30, wherein a third drain opening joining a third drain line is located between 7 o'clock and 8 o'clock.
