摘要： In turbomachinery, first and second flowpaths coupled to stages of the compressor flow cooling medium at different temperatures and pressures to components of the turbine. An ejector is provided in the first flowpath for suctioning flow from the second flowpath and combining the two flows for delivery to a component of the turbine at a temperature and pressure intermediate the temperature and pressure of the first and second flows. A flow sensor, flow controller and throttling valve are interposed in the motive flowpath, the exit flowpath or the suction flowpath relative to the ejector for controlling the flow through the ejector.

摘要： Leakage flows through seals are used to cool components of a turbine downstream of the seals. At certain seal locations, the leakage flows are restricted to the extent that cooling of downstream components cannot be effected by the leakage flows. The cooling air leakage flow is augmented by extracting bleed air from different stages at different temperatures from a compressor and combining the extracted flows in an ejector to provide a flow having a temperature intermediate the temperatures of the extracted flow streams for augmenting the leakage flow to cool the component. The ejector thus uses high extraction air to entrain lower temperature extraction air to lower the ejector exit air temperature, reducing the magnitude of air required to cool the downstream component and enhancing the effectiveness of the advanced seal.
