Abstract

A combined cycle power plant includes a gas turbine and an afterburner to which fuel is supplied for speed and load control. Water is injected into the turbine combustors by a controlled water injection system to control total NOx emissions from the turbine and the afterburner as a function of turbine load corrected for changes in inlet air temperature and inlet guide vane position.
