GAS TURBINE ELECTRIC GENERATING SET

FIELD: mechanical engineering; power generating equipment. SUBSTANCE: proposed gas turbine electric generating set has container accommodating gas turbine engine with power turbine, transmission, behind-the-turbine diffuser, reduction gear and useful load unit, and also air intake and exhaust devices. Proposed set is furnished also with air vent device and noise damping unit. Said noise damping unit and useful load unit are connected by flexible envelope inside container. Air intake device is placed between engine and reduction gear. Outlet part of air intake device is arranged in container and it encloses transmission. Inlet of air vent device is located opposite to behind the-turbine diffuser at outlet of which compensating unit is installed including at least two ring flanges with flexible sealing in between, and screen enclosing the unit. One of ring flanges is connected with behind-the turbine diffuser forming resonator chamber together with flexible sealing. Outlet of chamber is pointed to side of combustion products flow. Other ring flange forms, together with screen and flexible sealing, end space whose outlet is pointed to engine side. EFFECT: increased efficiency, reliability and improved cooling of engine housing. 4 cl, 5 dwg
