Abstract
Disclosed is a method for non-catalytically reducing the amount of NO emitted from gas turbines. The method involves contacting condition effluents of the gas turbine with ammonia, replacing at least a portion of the secondary air used to dilute and cool the combustion effluents with an inert gas, such as exhaust gas from the gas turine. The temperature of the combustion effluents, the time between contacting the combustion effluents with ammonia and passage through the turbine blades, and the amount of ammonia employed is determined by the solution of the set of simultaneous equations derived from the kinetic model disclosed herein.
