FIELD: machine building.
SUBSTANCE: proposed compressor comprises annular flow section for medium to be compressed therein, at least, one bleed hole in outer wall and, at least, one hole on casing. Flow section is radially confined from outside by annular outer wall. Casing covers outer wall to form, at least, one collection chamber there between. Outer wall hole serves to divert portion of medium from aforesaid flow section. Casing hole serves to divert medium portion diverted therefrom Collection chamber accommodates baffle to divide it into radial inner and outer compartments for notable decrease in inner compartment medium heat ingress into said casing compared to collection chamber without said baffle. Said baffle has, at least, one hole communicated via channel with casing hole to remove medium portion diverted therefrom. Outer compartment is composed of closed chamber that makes isolating chamber between inner compartment and casing. Invention relates also to stationary axial-flow gas turbine with above described compressor.
EFFECT: higher efficiency.
