ABSTRACT:
A high speed centrifugal compressor is closely directly coupled to the power turbine of a two-shaft gas turbine having a gas generator section separate from its power turbine. Through the direct close coupling and center-line mounting of the gas turbine exhaust casing for free and uniform heat expansion, alignment between stationary and rotating parts of the power turbine and compressor is maintained free from mechanical problems. Bearings and oil seals are fed by an integrated lubrication and a sealing oil system utilizing a compact oil distribution manifold assembly incorporating a quick filter change structure. The gas turbine-compressor finds particularly useful application in areas where high power, compact, relatively maintenance-free units are required, as, for example, on offshore platforms in the natural gas industry.
