Abstract
A fuel nozzle apparatus can include a nozzle that functions with two or more modes of operation with respect to a group of fuels, and an air shroud fixed over the nozzle. The air shroud blocks air through the nozzle or allows air through the nozzle in a predefined pattern. When a position of the air shroud is varied, the amount of the air and the location of the air into the nozzle is changed to facilitate the two or more modes of operation with respect to the group of fuels.
Claims20
A fuel nozzle apparatus, comprising:
- a nozzle that functions with at least two modes of operation with respect to a plurality of fuels;
- and
- an air shroud fixed over the nozzle, wherein the air shroud blocks air through the nozzle or allows air through the nozzle in a predefined pattern, wherein when a position of the air shroud is varied, an amount of the air and a location of the air into the nozzle is changed to facilitate the at least two modes of operation with respect to the plurality of fuels wherein, in a first mode of operation of the at least two modes of operation, a first set of slots of the air shroud overlaps with a first set of slots, of a plurality of slots, of the nozzle, and wherein, in a second mode of operation of the at least two modes of operation, a second set of slots of the air shroud overlaps with a second set of slots of the plurality of slots of the nozzle, wherein a count of slots in the first set of slots is more than a count of slots in the second set of slots.
A fuel nozzle apparatus, comprising:
- a nozzle that functions with at least two modes of operation with respect to a plurality of fuels;
- and
- an air shroud subject to a linear movement in an axial direction in which the position of the shroud is varied linearly, wherein the air shroud surrounds the nozzle and blocks air through the nozzle or allows air through the nozzle in a predefined pattern, wherein when a position of the air shroud is varied, an amount of the air and a location of the air into the nozzle is changed to facilitate the at least two modes of operation with respect to the plurality of fuels wherein, in a first mode of operation of the at least two modes of operation, a first set of slots of the air shroud overlaps with a first set of slots, of the plurality of slots, of the nozzle, and wherein, in a second mode of operation of the at least two modes of operation, a second set of slots of the air shroud overlaps with a second set of slots of the plurality of slots of the nozzle, wherein a count of slots in the first set of slots is more than a count of slots in the second set of slots.
A method of operating a fuel nozzle apparatus, comprising:
- providing a nozzle that is configured to functions with at least two modes of operation with respect to a plurality of fuels wherein the nozzle is having a surface defining a plurality of slots to allow air into a combustion chamber;
- surrounding an air shroud over the nozzle wherein the air shroud is having a surface defining a plurality of slots to allow air flow into the plurality of slots of wherein in a first mode of operation of the at least two modes of operation, a first set of slots of the air shroud overlaps with a first set of slots, of the plurality of slots, of the nozzle, and wherein, in a second mode of operation of the at least two modes of operation, a second set of slots of the air shroud overlaps with a second set of slots of the plurality of slots of the nozzle, wherein a count of slots in the first set of slots is more than a count of slots in the second set of slots;
- and
- varying a position of the air shroud wherein an amount of the air and a location of the air into the nozzle is changed to facilitate the at least two modes of operation with respect to the plurality of fuels.
