Pollution reduction fuel efficient combustion turbine

A combustion chamber in a combustion turbine is operated in a fuel rich mode, so that combustion is incomplete in the combustion chamber. Additional air can be added either in the expansion turbine or in additional combustion chambers, with additional combustion taking place either in the expansion turbine or in the additional combustion chambers. The process is better able to maintain a steady temperature throughout the expansion turbines, achieving higher efficiencies and more nearly approximately the more efficient infinite reheat cycle than the simple Brayton cycle. The atmosphere at the exit to the combustion chamber is reducing, rather than the normal oxidizing atmosphere, so oxidation of nitrogen to produce NOx is lessened, and the ability to use other alloys is enhanced. Emissions of CO2, a greenhouse gas, are reduced per unit of power produced.
