Abstract
A combustor for a gas turbine, including: a combustor chamber; a casing enclosing the combustor chamber and defining an area therebetween for passing compressor discharge air into the combustor chamber for use in combustion; and at least one passive bypass valve for selectively extracting a portion of the compressor discharge air from the area between the combustor chamber and the casing to adjust a temperature in the combustor.
Claims16
A combustor for a gas turbine, comprising:
- a combustor chamber;
- a compressor discharge casing (CDC) enclosing the combustor chamber and defining a CDC volume therebetween for passing compressor discharge air into the combustor chamber for use in combustion;
- and
- a plurality of passive bypass valves for selectively extracting a portion of the compressor discharge air from the CDC volume between the combustor chamber and the compressor discharge casing to adjust a temperature in the combustor,
- wherein a first of the plurality of passive bypass valves is positioned between the CDC volume and a nozzle of a turbine component of the gas turbine, and wherein a second of the plurality of passive bypass valves is positioned between the CDC volume and a transition duct at a downstream end of the combustor chamber.
