Patent ID: 8397482

Claim:
A power generation system for a gas turbine engine comprising, in combination: a first compressor having an inlet for ambient air, means for increasing the pressure of said ambient air and an outlet for compressed ambient air; a combustor downstream of said first compressor having inlets for said compressed ambient air, compressed exhaust gases and fuel, and being capable of combusting a mixture of said fuel, said compressed exhaust gases and said compressed ambient air to generate a high temperature exhaust gas through a combustor outlet; a turbine downstream of said combustor having an inlet coupled to the outlet of said combustor, turbine blades moveable by the force of said high temperature exhaust gas, and an outlet for partially spent exhaust gas containing about 4% or less oxygen; a 3-way catalytic reactor downstream of said turbine having an inlet to receive and contact said partially spent exhaust gas, said 3-way catalytic reactor being capable of removing substantially all of the NO x components present in said partially spent exhaust gas; a heat recovery steam generator (HRSG); a second compressor for increasing the pressure of an exhaust gas recycle (EGR) stream and feeding said EGR stream to said combustor to said turbine; and an electrical generator coupled to said gas turbine engine for generating electricity.
