Abstract
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.
