Abstract: A system including a gas turbine engine having a compressor portion, a combustion portion and an exhaust portion is disclosed. The system includes a first regulating nozzle for injecting water into the compressor portion, a second regulating nozzle for injecting water into the combustion portion, a third regulating nozzle for injecting water into the exhaust portion, and a condenser apparatus for extracting water from flue gases in the exhaust portion. The system further includes a pump for pumping water from the condenser apparatus to the first, second and third regulating nozzles, wherein said nozzles inject water supplied solely from the condenser apparatus, and a processor communicatively coupled to said regulating nozzles, wherein the processor is configured for transmitting control signals to the first, second and third regulating nozzles, and wherein the control signals are configured to command said regulating nozzles to inject predefined amounts of water.
