Abstract: A gas turbine engine having a combustor is disclosed in which a heat exchanger is disposed within the combustor. The heat exchanger can take the form of a fuel/air heat exchanger. In one form the heat exchanger includes a path for cooling air to be conveyed to a location external to the combustor. Cooled cooling air carried through the path can be created through action of heat transfer from the cooling air to a fuel flowing in the heat exchanger. The heat exchanger can include a fuel vaporizer in one form.

Abstract: The present invention relates generally to a lean premix module for an industrial gas turbine engine to satisfy increasingly stringent environmental requirements. A combustion system of the present invention employs a lean premix technique to meet the engine operability requirements and high power emission targets without the use of combustor diluent injection or post combustor exhaust treatment. A lean premix combustion mode is utilized to minimize primary zone combustion temperatures and limit the oxides of nitrogen production during high power engine operation. In one form of the present invention, the lean premix combustion is carried out in an off centerline silo combustor having a plurality of lean premix modules positioned parallel within a common liner. The lean premix modules receive the air from the compressor into a radial swirler and the fuel is dispensed along the radial swirler in order to be premixed with the air. A nozzle having a converging-diverging section is utilized to accelerate the fluid flow in the converging portion to prevent flashback, and in the diverging portion to expand the fluid flow to induce a centrally located recirculation zone. In another form of the present invention, the lean premix module is located inline in a can-annular combustion system.
