Abstract:
1. A method for supplying cooling and/or sealing fluid flow in turbomachinery, comprising: a) establishing a first fluid flow in the turbomachinery and flowing the first fluid flow to a first site in the exterior of the turbomachinery; b) establishing a second fluid flow at said first site, said second fluid flow having pressure higher than the pressure of said first fluid flow; and c) delivering said second fluid flow to a second site in the interior of the turbomachinery, wherein the step of establishing a first fluid flow includes extracting the first fluid flow from a stage of a compressor forming part of the turbomachinery, and the step of establishing a second fluid flow includes passing the first fluid flow through an external booster compressor, the method further including establishing a third fluid flow in the turbomachinery and delivering the third fluid flow into said second site of the turbomachinery, wherein the step of establishing a third fluid flow in the turbomachinery includes extracting the third fluid flow from another stage of said compressor forming part of the turbomachinery at a pressure higher than the pressure of said first fluid flow.
