Abstract
A method for assembling a nozzle is provided. The method includes providing an injection tube that includes an outlet that is configured to discharge fuel therefrom. A face plate is also provided that extends about the injection tube such that the face plate substantially circumscribes the outlet. A cooling chamber is defined within the injection tube and configured to channel cooling fluid adjacent to the face plate. At least one surface defining the cooling chamber is configured to disrupt a flow of the cooling fluid flowing through the cooling chamber.
Claims17
A method for assembling a nozzle, said method comprising:
- providing an injection tube that includes an outlet that is configured to discharge fuel therefrom into a gasifier;
- and
- providing a face plate that extends about the injection tube such that the face plate substantially circumscribes the outlet, wherein the face plate includes an outer surface and an opposite inner surface such that the outer surface defines a discharge end of the nozzle adjacent the outlet;
- defining a cooling chamber within the injection tube that extends along the face plate inner surface, and that is configured to channel cooling fluid adjacent to the face plate such that the cooling fluid is substantially isolated from the fuel in the injection tube;
- forming a plurality of projections extending substantially perpendicularly from the face plate inner surface and only partially across the cooling chamber;
- orienting the plurality of projections to turbulate a flow of the cooling fluid flowing through the cooling chamber and to facilitate increasing contact between the turbulated cooling fluid and the face plate.
A nozzle for a gasifier, said nozzle comprising:
- an injection tube comprising an outlet configured to discharge fuel into the gasifier;
- a face plate substantially circumscribing said outlet, said face plate comprising an outer surface and an opposite inner surface such that said outer surface defines a discharge end of said nozzle adjacent said outlet;
- and
- a cooling chamber defined within said injection tube, said cooling chamber extending along said inner surface and configured to channel cooling fluid adjacent to said face plate and to substantially isolate the cooling fluid from the fuel in the injection tube, said cooling chamber at least partially defined by said inner surface and comprising a plurality of projections extending substantially perpendicularly from said inner surface and only partially across said cooling chamber, said plurality of projections oriented to turbulate a flow of the cooling fluid within said cooling chamber and to facilitate increasing contact between the turbulated cooling fluid and said face plate.
A gasifier comprising:
- a fuel supply that channels fuel to the gasifier;
- and
- a nozzle that discharges the fuel into the gasifier, said nozzle comprising:
- an injection tube comprising an outlet configured to discharge the fuel into the gasifier;
- a face plate substantially circumscribing said outlet, said face plate comprising an outer surface and an opposite inner surface such that said outer surface defines a discharge end of said nozzle adjacent said outlet;
- and
- a cooling chamber defined within said injection tube, said cooling chamber extending along said inner surface and configured to channel steam adjacent to said face plate and to substantially isolate the cooling fluid from the fuel in the injection tube, said cooling chamber defined by said inner surface and comprising a plurality of projections extending substantially perpendicularly from said inner surface and only partially across said cooling chamber, said plurality of projections oriented to turbulate a flow of the steam within said cooling chamber and to facilitate increasing contact between the turbulated flow of steam and said face plate.
