Thermal and Economic Analysis of Gas Turbine Steam Injection Plant

Steam injection into gas turbine combustion chamber increases the power output and lowers the NOx emissions. Steam may be produced in a heat recovery steam generator (HRSG), using gas turbine exhaust gases. Steam which is usually injected with pressure of combustion chamber, increases the mass flow rate flowing through turbine and decreases the combustion temperature, hence, lowering the amount of NOx emissions. This power augmentation method is...
