Abstract
A control system for the injection of water or steam into the combustion chambers of a combustion turbine for reducing the emission of oxides of nitrogen in the exhaust gas of a combustion turbine is described. The control system includes a water control valve having a linear flow versus stroke characteristic which is controlled by an error signal representing the difference between a predetermined water-to-fuel schedule and the actual water-to-fuel schedule. Instruments for monitoring and recording water and fuel flow are also described.
