Abstract: Embodiments of the present disclosure provide injection systems for fuel and air. According to one embodiment, an injection system can include a mixing zone embedded within a surface of a turbine nozzle and positioned between a first outlet and a second outlet, the turbine nozzle separating a combustor of a power generation system from a turbine stage of the power generation system, wherein the first outlet is oriented substantially in opposition to the second outlet; a first injection conduit for delivering a carrier gas to the mixing zone through the first outlet; and a second injection conduit for delivering a fuel to the mixing zone through a second outlet; wherein the carrier gas and the fuel intermix within the mixing zone upon leaving the first injection conduit and the second injection conduit.

Abstract: A turbomachine fuel-air mixer component includes a first component portion formed from a non-additive manufacturing process. The first component portion includes a plurality of tube elements each having an end portion. A second, additively manufactured component portion is additively joined to the first component portion. The second, additively manufactured component portion includes a plurality of additively manufactured tube sections constructed at, and fluidically connected with, respective ones of each end portion of the plurality of tube elements. The first and second component portions collectively defining at least a portion of the turbomachine fuel-air mixer component.
