Abstract
An assembly is provided for a turbine engine. This assembly includes a combustor, a fuel injector nozzle and a fuel system. The combustor includes a combustion chamber. The fuel injector nozzle is configured to inject a fuel-steam mixture into the combustion chamber for combustion. The fuel system includes a fuel source, a steam source and a manifold. The manifold is configured to mix fuel received from the fuel source with steam received from the steam source to provide the fuel-steam mixture. The fuel system is configured to deliver the fuel-steam mixture to the fuel injector nozzle.
Claims15
An assembly for a turbine engine, comprising:
- an annular combustor comprising an annular combustion chamber;
- a fuel injector nozzle configured to inject a fuel-steam mixture into the annular combustion chamber for combustion;
- and
- a fuel system including a non-hydrocarbon fuel source, a steam source and a manifold, the steam source including a water reservoir fluidly coupled to an evaporator, the manifold configured to mix a non-hydrocarbon fuel received from the non-hydrocarbon fuel source with steam received from the steam source to provide the fuel-steam mixture, and the fuel system configured to deliver the fuel-steam mixture to the fuel injector nozzle,
- wherein the non-hydrocarbon fuel comprises hydrogen gas.
An assembly for a turbine engine, comprising:
- a non-hydrocarbon fuel source;
- a steam source including a water reservoir fluidly coupled to an evaporator;
- a manifold comprising an internal volume fluidly coupled with and downstream of the non-hydrocarbon fuel source and the steam source, the manifold configured to receive a non-hydrocarbon fuel from the non-hydrocarbon fuel source and the manifold configured to mix the non-hydrocarbon fuel with steam received from the steam source to provide the fuel-steam mixture;
- and
- a combustor section including an annular combustor and a plurality of fuel injector nozzles, the annular combustor comprising an annular combustion chamber, each of the plurality of fuel injector nozzles including an outlet orifice and an internal passage fluidly coupled with and between the internal volume and the outlet orifice, and each of the plurality of fuel injector nozzles configured to direct the fuel-steam mixture out of the internal passage, through the outlet orifice, for combustion within the annular combustion chamber,
- wherein the non-hydrocarbon fuel source is a gas fuel source and the non-hydrocarbon fuel comprises hydrogen gas.
