Abstract
A combustor having a plurality of nozzles (main nozzles) to supply fuel disposed, includes a water supplier that is connected to all or part of the plurality of nozzles to supply water to each of a plurality of fuel pipes. The water supplier is configured to vary a supply amount of water for each of plurality of nozzles to which the water is supplied.
Claims9
A combustor having only one first nozzle configured to receive fuel via a first fuel supply line and a plurality of second nozzles which are positioned around the only one first nozzle and are configured to receive fuel via second fuel supply lines different from the first fuel supply line, the combustor comprising:
- a water supplier that is connected to all or part of the plurality of second nozzles and configured to supply water to each of a plurality of fuel pipes,
- wherein the water supplier is configured to vary water supply for each of the plurality of second nozzles to which the water is supplied, and
- wherein a first supply amount of water and a second supply amount of water are supplied alternately to the plurality of second nozzles arranged consecutively in a circumferential direction around the only one first nozzle.
A combustor having only one first nozzle configured to receive fuel via a first fuel supply line and a plurality of second nozzles which are positioned around the only one first nozzle and are configured to receive fuel via second fuel supply lines different from the first fuel supply line, the combustor comprising:
- a water supplier that is connected to all or part of the plurality of second nozzles and configured to supply water to each of a plurality of fuel pipes,
- wherein the water supplier is configured to vary water supply for each of the plurality of second nozzles to which the water is supplied, and
- wherein a first supply amount of water is supplied to some of the plurality of second nozzles arranged consecutively in a circumferential direction around the only one first nozzle and a second amount of water is supplied to others of the plurality of second nozzles arranged consecutively in the circumferential direction around the only one first nozzle.
A combustor having only one first nozzle configured to receive fuel via a first fuel supply line and a plurality of second nozzles which are positioned around the only one first nozzle and are configured to receive fuel via second fuel supply lines different from the first fuel supply line, the combustor comprising:
- a water supplier that is connected to all or part of the plurality of second nozzles and configured to supply water to each of a plurality of fuel pipes,
- wherein the water supplier is configured to vary water supply for each of the plurality of second nozzles to which the water is supplied, and
- wherein the plurality of second nozzles are configured such that supply amounts of water increase or decrease according to an order of the second nozzles in a circumferential direction around the only one first nozzle.
