Abstract
There are provided an injector and an associated method for injecting and mixing gases, comprising a carbonaceous fuel and oxygen, in a combustion chamber of a combustion device. The injector has jets, which can be used to separately inject different combustion fuels. The injector is compatible with combustion devices that inject only gases, for example, a reheater that provides initial combustion in a power generation cycle or a reheater that recombusts a discharged gas from a gas generator and turbine. Further, the injector defines an annular space through which a recycle gas can be injected into the combustion chamber to lower the combustion temperature.
Claims38
An injector for injecting combustion fluids into a combustion chamber, comprising:
- an injector body defining a first annular space between the injector body and a first sleeve, said injector body comprising an injector face facing the combustion chamber, and defining a main bore, at least one main jet extending from the injector face to the main bore, a first plurality of fuel jets opening through the injector face, a first fuel inlet fluidly connected to the first plurality of fuel jets, a second plurality of fuel jets opening through the injector face, and a second fuel inlet fluidly connected to the second plurality of fuel jets,
- wherein each of the second plurality of fuel jets has a smaller cross sectional area than each of the first plurality of fuel jets.
An injector for injecting combustion fluids into a combustion chamber, comprising:
- an injector body defining a first annular space between the injector body and a first sleeve, said injector body comprising an injector face facing the combustion chamber, and defining a main bore, at least one main jet extending from the injector face to the main bore, a first plurality of fuel jets opening through the injector face, a first fuel inlet fluidly connected to the first plurality of fuel jets, a second plurality of fuel jets opening through the injector face, and a second fuel inlet fluidly connected to the second plurality of fuel jets,
- wherein a respective one of the fuel jets defines a converging angle relative to a respective main jet such that fluid flowing from the injector body into the combustion chamber through the respective fuel jet impinges on a stream of fluid flowing from the respective main jet in the combustion chamber.
