A fuel injector for a combustor of a gas turbine engine is disclosed herein. The fuel injector includes a fuel delivery system for receiving and distributing fuel and an injector body. The injector body includes a primary fuel gallery, a pilot fuel gallery, a primary perforated plate, and a pilot distributor plate. The primary fuel gallery is formed as an annular cavity in the injector body and extends around an assembly axis. The primary fuel gallery and the pilot fuel gallery are in flow communication with the fuel delivery system. The primary perforated plate is disposed within the primary fuel gallery and divides the primary fuel gallery. The primary perforated plate having a first perforation to restrict flow. The pilot distributor plate is disposed within the center body assembly and radially inward of the first portion of the primary gallery, adjacent to portions of the tube stem. The pilot distributor plate having a pilot distributor passage to restrict flow.

Fuel injector with perforated plate

A fuel injector for a combustion engine includes an injector head including a nozzle, a premixer, and a distributor structured to distribute a plurality of different fuels to different sets of fueling orifices in the premixer. A pilot assembly of the fuel injector is coupled to the premixer and includes a first fueling passage for a first fuel and a second fueling passage for a second fuel. Multiple sets of fueling orifices are positioned within the fuel injector, the fueling orifice sets being selectively connectable to a plurality of different fuel supplies, and both located and sized so as to accommodate a wide range of flow rates to enable a combustion engine coupled with the fuel injector to operate on fuels having a range of Wobbe numbers and compositions.
