Abstract: An assembly for a gas turbine engine includes at least one burner and a hydrogen manifold. The at least one burner includes an outer nozzle and an inner nozzle. The outer nozzle forms a combustion chamber. The outer nozzle includes an outer converging axial portion and an outer diverging axial portion. The outer converging axial portion is disposed at an upstream axial end of the outer nozzle. The outer diverging axial portion is disposed axially downstream of the outer converging axial portion. The inner nozzle includes an inner converging axial portion at a downstream axial end of the inner nozzle. The inner converging axial portion is disposed within the outer converging axial portion to form an annular gap between the outer converging axial portion and the inner converging axial portion. The hydrogen manifold is disposed at the upstream axial end. The hydrogen manifold is connected in fluid communication with the annular gap.

Abstract: A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.

Abstract: An engine can utilize a combustor to combust fuel to drive the engine. A fuel nozzle assembly can supply fuel to the combustor for combustion or ignition of the fuel. The fuel nozzle assembly can include a swirler and a fuel nozzle to supply a mixture of fuel and air for combustion. The fuel nozzle assembly can be configured to increase lateral provision of fuels to reduce flame scrubbing on combustor liners for the combustor.

Abstract: The present invention provides methods and system for power generation using a high efficiency combustor in combination with a CO2 circulating fluid. The methods and systems advantageously can make use of a low pressure ratio power turbine and an economizer heat exchanger in specific embodiments. Additional low grade heat from an external source can be used to provide part of an amount of heat needed for heating the recycle CO2 circulating fluid. Fuel derived CO2 can be captured and delivered at pipeline pressure. Other impurities can be captured.
