Abstract
A dual fuel injection system for a low Nox combustor in which separate gaseous and liquid fuel manifolds are integrally joined to form manifold assemblies. Each manifold assembly extends circumferentially around the inlet of an annular fuel and air mixing passage. The gaseous fuel manifolds have a number of gas discharge ports spaced around their circumferences. The liquid fuel manifolds have a number of fuel nozzles spaced around their circumferences. The gaseous fuel discharge ports and liquid fuel nozzles are oriented so as to inject fuel into the annular passages in a manner that will facilitate mixing of the fuel and air. Separate gaseous and liquid fuel supply tubes are connected to each manifold.
