Abstract

An injector (38) for a gas turbine engine (20) includes an annular gas nozzle (42), a hydrogen feed conduit (50), and a disc (58). The annular gas nozzle (42) is disposed along a central nozzle axis (A2) and includes a forward face (44), a frustoconical interior surface (46), and gas feed conduits (48) that open at the frustoconical interior surface (46). The hydrogen feed conduit (50) extends along the central nozzle axis (A2) through the annular gas nozzle (42). The hydrogen feed conduit (50) and the frustoconical interior surface (46) define there between an annular mixing chamber (52). The hydrogen feed conduit (50) has an end portion (54) that is axially displaced from the forward face (44). The end portion (54) includes feed holes (56) that open into the mixing chamber (52). The disc (58) is disposed on the end portion (54) and is diametrically larger than the end portion (54) so as to form a forward boundary of the annular mixing chamber (52). The disc (58) may have multiple teeth, serrated edges, single or multiple bleed holes that are normal or angularly drilled to enhance fuel and air mixing, and improve flame stability.
