摘要:
A system for producing a hydrogen enriched fuel includes a gas turbine comprising a compressor, a combustor, and a turbine. A fuel reformer is connected between the compressor and the combustor. The fuel reformer comprises an inlet connected to the compressor and an outlet connected to the combustor, and the fuel reformer produces the hydrogen enriched fuel. A method for producing a hydrogen enriched fuel includes compressing a working fluid with a compressor to produce a compressed working fluid and diverting a first portion of the compressed working fluid to a fuel reformer. The method further includes mixing a fuel with the compressed working fluid in the fuel reformer to produce the hydrogen enriched fuel and an exhaust stream and flowing the exhaust stream to a combustor

In one aspect, an exhaust diffuser for a gas turbine is disclosed. The exhaust diffuser may generally include an inner casing and an outer casing spaced radially apart from the inner casing so as to define a passage for receiving exhaust gases of the gas turbine. Additionally, the exhaust diffuser may include a fluid outlet configured to inject a fluid into the exhaust gases flowing through the passage.

A gas turbine includes a compressor with a plurality of pressure plates, a combustor downstream from the compressor, and a turbine downstream from the combustor and axially aligned with the compressor. The combustor produces combustion gases that flow to the turbine. A first manifold connected to the combustor contains a first process gas for combustion in the combustor. A second manifold connected upstream of the turbine contains a second process gas, and a portion of the second process gas flows to the plurality of pressure plates.

A fuel control system for a gas turbine engine that includes a primary fuel circuit, a fuel tuning circuit, a plurality of combustors connected to the fuel tuning circuit, oxygen and carbon dioxide sensors in the exhaust stream and a feedback control loop operatively connected to the fuel tuning circuit and to the oxygen and carbon monoxide sensors which serve to control the precise amount of fuel and air being fed to each one of the plurality of combustors in the engine. A parallel array of control valves in a tuning fuel circuit connect to corresponding ones of the plurality of combustors in the gas turbine engine. The fuel control system thereby “fine tunes” the amount of fuel and air being fed to each combustor using data regarding the detected oxygen and carbon monoxide concentrations in the exhaust gas as provided through a feedback control loop.

A power plant arrangement and method of operation are provided. The power plant arrangement comprises at lease one main air compressor and one or more gas turbine assemblies. Each assembly comprises a turbine combustor for mixing a portion of a compressed ambient gas flow with a portion of a recirculated low oxygen content gas flow and a fuel stream, and burning the combustible mixture to form the recirculated low oxygen content flow. The assembly further comprises a turbine compressor, fluidly connected to the turbine combustor, and connected to a turbine shaft that is arranged to be driven by rotation of a turbine. The assembly also comprises a recirculation loop for recirculating at least a portion of the recirculated low oxygen content gas flow from the turbine to the turbine compressor.
