FIELD: mechanical engineering; gas turbine plants. SUBSTANCE: gas turbine plant has compressor, combustion chamber with primary and secondary air supply branch pipes and fuel feed device, all connected in tandem in direction of flow of working medium. Fuel feed device is made in form of ejector with tandem- connected intake chamber, mixing chamber and diffuser. Active nozzle of ejector is connected to fuel branch pipe in which fuel valve is installed. Passive nozzle communicates with atmosphere through primary air supply branch pipe. Primary air supply branch pipe of ejector and air branch pipe of compressor are provided with valves and are connected to common air intake. EFFECT: possibility of utilization of low-calorie high-pressure gases in gas turbine plant, increased summary (electric and thermal) power output of plant, possibility of plant control. 1 dwg
