Abstract: A fuel nozzle assembly includes a fuel plenum body including a forward plate, an aft plate, an outer band extending between the forward plate and the aft plate and a fuel plenum defined within the fuel plenum body. A plurality of tubes extends through the forward wall, the fuel plenum and the aft wall and each tube defines a premix flow passage through and downstream from the fuel plenum body. Each tube is rigidly connected to the aft plate. A damping plate is disposed downstream from the aft plate. At least one tube of the plurality of tubes extends through a corresponding tube opening defined by the damping plate. The damping plate includes a plurality of spring members fixedly connected to the damping plate. At least one spring member of the plurality of spring members is engaged with an outer wall of the at least one tube.

Abstract: A combustion burner and a nozzle tip to a combustion burner is disclosed. The nozzle tip includes a face and at least one passage at the face enabling a gas impinging on the face to flow through the nozzle tip. At least one rib extends from the face to transfer heat from the nozzle tip to the impinging gas. The at least one rib extending from the face of the nozzle tip provides a surface area of the face that is greater than the surface area of a planar face. The nozzle tip can be coupled to an end of a nozzle of the combustion burner. The gas can be an air and/or an air/fuel mixture.
