Abstract
A gas turbine engine combustor can operate on either liquid fuel or gaseous fuel while maintaining low levels of nitrous oxide emissions. An upstream end of each of a plurality of mixing tubes includes an external manifold that is supplied with gaseous fuel. The gaseous fuel is injected into the mixing tubes through a plurality of orifices with sufficient momentum to be uniformly distributed across the flow path of each mixing tube. The optimum fuel/air ratio for low nitrous oxide emissions does not exceed seventy five percent (75%) of the stoichiometric ratio for a given fuel.
