FIELD: mechanical engineering. SUBSTANCE: invention can be used in gas transfer sets with gas-turbine plant at drive. Proposed gas outlet device of gas-turbine plant contains axially radial diffuser communicating with exhaust pipe. Axially radial diffuser is made with outlines at which flow duct of diffuser in cross section has ω-shaped (omega-shape) profile, being divided by partitions installed equidistantly relative to outlines of outer wall of diffuser. EFFECT: increased efficiency of gas turbine plant owing to reduction of hydraulic resistance in gas outlet device. 2 dwg
