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.
Claims10
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, characterized it that it envisages 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 aforementioned inner barrel (23) so as to allow a variation in the flow of air entering into the aforementioned inner barrel (23), by means of the selection and replacement of at least some of the aforementioned nozzles (11) with other nozzles (11) having an internal bore (51) with suitable diameters.
Device (10) according to the preceding claims, characterized in that, in order to fix the aforementioned nozzles (11) in the operating position, it is further envisaged using a dimpling punch, which is used by employing the guide tube (17) as a guide for the striking point.
Device for controlling the cooling flows of gas turbines, all of which as substantially described and illustrated in the accompanying drawings.
