FIELD: gas-turbine systems. SUBSTANCE: gas-turbine system includes gas-turbine unit for drive of recovery unit and generation of hot exhaust gases. System contains recuperative heat exchanger including working fluid medium which interacts with hot exhaust gases escaping from gas-turbine unit forming evaporated working fluid medium and cooled gases which are exhausted. When use is made of organic working fluid, turbine connected with generator interacts with evaporated organic working fluid, thus generating electric energy and expanded organic vapor escaping from turbine. Expanded evaporated fluid medium is condensed and condensate is returned to recuperative heat exchanger. Temperature of hot gases is regulated by means of control device which contains mixture for mixing the ambient air with hot exhaust gases before feeding it to recuperative heat exchanger and interacts with organic fluid medium. Control device may be provided with selective position valve for control of amount of ambient air mixed with hot exhaust gases. Device may contain hot gas temperature sensor and valve control member which responds to temperature recorded by sensor for control of valve position. EFFECT: enhanced efficiency. |
