  • Inner casing cooling passage for double flow turbine
    Patent number: 10677092
    Abstract: A turbomachine structure having a first inner casing including a first and second flowpath oriented in opposing axial directions to one another; a second inner casing surrounding the first inner casing and including a third and fourth flowpath, wherein the third flowpath is fluidly connected to the first flowpath and the fourth flowpath is fluidly connected to the second flowpath; an extraction chamber defined between the first and second inner casings; a cooling passage defined between the first and second inner casings; a first extraction port fluidly connected to the cooling passage and to the first flowpath at a location in the first flowpath having a first pressure; and a second extraction port fluidly connected to the extraction chamber and to the second flowpath at a location in the second flowpath having a second pressure less than the first pressure.
