APPARATUS FOR REMOVING EXHAUST GASES OF A GAS TURBINE ENGINE Russian patent published in 2022 - IPC F01D25/30 

FIELD: engines.

SUBSTANCE: invention relates to exhaust branch pipes and can be included in gas turbine units of gas pumping sets. Apparatus comprises a body with an inlet located around the axis of rotation of the turbine, a diffuser including an axial and a radial parts formed, accordingly, by the internal and the external duct walls located inside the body around the axis of rotation of the turbine, and an outlet located in the outer wall of the body. The front wall is made at an inclination, and the back end of the outer duct wall is made obliquely cut. A two-way flow divider, a blast fence, and a dual-slope deflector are additionally introduced into the structure.

EFFECT: reduction in the hydraulic resistances, fuel gas consumption, thermal stresses on the structural elements of the gas removal duct, and reduction in the level of noise of the gas removal duct.
