WIPO Patent Application WO2001088354
Kind Code:
A3
Abstract:
A device (10) for controlling the cooling flows of gas turbines (20), where the aforementioned gas turbine (20) is provided with a compressor (21) with which an inner barrel (23) and a load-bearing bolster (24) are associated, the device (10) envisaging the arrangement of a plurality of replaceable nozzles (11) which have an internal bore (51) with different diameters and which can be mounted in suitable holes (14) formed in the substantially cylindrical body (50) of the inner barrel (23) so as to allow variation in the flow of air entering into the inner barrel (23), by means of the selection and replacement of at least some of these nozzles (11) with other nozzles (11) having an internal bore (51) with suitable diameters.
