    Abstract: A gas turbine rotor has an essentially closed loop cooling air scheme in which cooling air drawn from the compressor discharge air that is supplied to the combustion chamber is further compressed, cooled, and then directed to the aft end of the turbine rotor. Downstream seal rings attached to the downstream face of each rotor disc direct the cooling air over the downstream disc face, thereby cooling it, and then to cooling air passages formed in the rotating blades. Upstream seal rings attached to the upstream face of each disc direct the heated cooling air away from the blade root while keeping the disc thermally isolated from the heated cooling air. From each upstream seal ring, the heated cooling air flows through passages in the upstream discs and is then combined and returned to the combustion chamber from which it was drawn.

    Abstract: In relation to Fig. 2 of the drawing, a gas turbine with a compressor (18) and a turbine (20), bypasses a portion of the cool air from the compressor (18) into the turbine (20) through a conduit (30, 32), which conduit delivers the cool air to the inlet (33) of the turbine blades (26) so that the cool air (36) flows along the suction side of the turbine blades and maintains a stable flow condition with respect to the hot gases (37) along the pressure side of the turbine blades, with the result that the turbine blades are cooled by the cool air through the conduit (30).

    Abstract: The invention concerns an energetically advantageous method of cooling a component in a gas turbine plant and a gas turbine plant designed according to the invention. After compression by a compressor (6) in the gas turbine plant, a partial air mass flow (3) is branched off a main air mass flow (2) and is guided in a closed duct (9) to the component to be cooled, the partial air mass flow (3) being subjected, independently of the main air mass flow (2), to additional compression which is carried out using the rotational energy of a turbomachine shaft of the gas turbine plant. To that end, according to the invention, a correspondingly designed gas turbine plant comprises a secondary compressor (10). The invention is suitable in particular for use in stationary gas turbine plants.

    Abstract: An evaporatively cooled rotor for a gas turbine engine. Each rotor defines an internal cavity which includes a vaporization section that corresponds generally to the blade section of the rotor and a condensing section that corresponds generally to the hub section of the rotor. A radial array of circumferentially disposed capture shelves is provided in the vaporization section for capturing cooling fluid contained within the internal cavity and flowing radially outward under the centrifugal field generated during rotation of the rotor. A barrier disposed along the inner surface of the rotor wall in the condensing section slows or temporarily stops the flow of cooling fluid prior to reaching the vaporization section and a perforated baffle attached to the capture shelves prevents cooling fluid from splashing out of the shelves.

    Abstract: An object (6, 8) to be cooled is placed within the constricted chamber region (18) of a cooling chamber (12) that has first and second open ends communicating with first and second chamber regions (14, 16) communicating with the constricted chamber region disposed therebetween. A mechanism (22, 22') for transporting a cooling medium is coupled to the first chamber end, and/or a second such transport mechanism (24, 24') is coupled to the second chamber end, the mechanisms being operated in push-pull fashion. These transport mechanisms and Venturi-like chamber cause the cooling medium entering the first chamber region to be compressed upon approaching the constricted chamber region, and to expand upon exiting the constricted chamber region and entering the second chamber region. Cooling medium velocity in the constricted chamber region is maximized, thereby promoting removal of heat from the object to be cooled.

    Abstract: The design of compressors for the cooling systems for combustion turbines is disclosed. Closed-loop air cooling systems and combustion turbines with ultra-low NOx emission combustion systems require nearly all of the compressor air to be pre-mixed with fuel. In either of these systems, it is necessary to extract a portion of the compressor delivery air, cool it, compress it and then re-introduce it into the combustion turbine. In the prior art, this was accomplished using an outside compressor. However, in accordance with the present invention, a compressor that supplies the required amount of increased pressure air for cooling hot end components is provided that is "on-board" or internal to the combustion turbine system. In preferred embodiments, an axial compressor receives a portion of compressor delivery air, is diverted at the compressor exit inner diameter and then compressed in one or more reduced height axial compressor stages located below the inner wall of the main compressor exit diffuser that is itself located directly downstream from the auxiliary compressor. Methods of cooling combustion turbines are also disclosed.
