Abstract
A method of lowered NOx combustion is taught wherein the kinetic rate of NOx formation is reduced for a given combustion temperature in a gas turbine combustor. A supply of fuel is provided along with a supply of ambient air in sufficient quantity to form a fuel/air mixture having an equivalence ratio greater than about 0.55 when mixed with the fuel. The fuel/air mixture is mixed with a supply of cooled combustion gases in sufficient quantity such that the oxygen content of the resulting air mixture is less than about 18 percent. The resulting air mixture is then passed into the combustor.
