Compressor Discharge Casing Clause Samples

Compressor Discharge Casing. The compressor discharge casing contains 13th- through 17th- stage compressor stators and one row of exit guide vanes. It also provides an inner support for the first-stage turbine nozzle assembly and supports the combustion components. Air is extracted from the compressor discharge plenum to cool the stage one nozzle vane, retaining ring, and shrouds. The compressor discharge casing consists of two cylinders connected by radial struts. The outer cylinder is a continuation of the compressor casing and the inner cylinder surrounds the compressor aft stub shaft. A diffuser is formed by the tapered annulus between the outer and inner cylinders. The compressor discharge casing is joined to the combustion wrapper at the flange on its outermost diameter.
