FIELD: machine building; power engineering.
SUBSTANCE: invention can be used in designs of turbo compressor plants with closed thermodynamic Brayton cycle. Turbo compressor power plant comprises turbo compressor, heater of working medium and heat exchanger-recuperator, all integrated into closed circuit. At output of direct-flow turbine impeller straightener is arranged in form of circular blade array formed by hollow blades with flow channels interconnected with concentrically arranged external and internal headers. Outer header is divided into two semi-headers, one of which is connected with compressor outlet, and other is with heat receiving path of heat exchanger-recuperator.
EFFECT: higher efficiency of power plant cycle and reducing its weight.
