Abstract
A gas turbine includes a combustor, an air lead-out member, an outer peripheral cover portion, an inner peripheral cover portion, and a fuel supply unit. A lead-out port of the air lead-out member is located radially outward of one end portion of the combustor. The combustor has a guide wall portion which is formed so as to connect mutually-adjacent combustion cylinders and guides air from an air flow path to an inner space via a communication path. Through holes are formed in the outer peripheral surface of each of the combustion cylinders and open to the inner space to allow air in the inner space to flow into the downstream side of a combustion chamber.
Claims6
A gas turbine comprising:
- a compressor;
- a combustor including a plurality of combustion cylinders arranged annularly;
- an air lead-out member configured to lead out air supplied from the compressor to the combustor;
- an annular outer peripheral cover portion configured to cover the combustor from radially outward of the combustor;
- an annular inner peripheral cover portion configured to cover the combustor from radially inward of the combustor;
- and
- a plurality of fuel supply units configured to supply fuel to upstream portions of combustion chambers of the plurality of combustion cylinders,
- wherein the combustor includes a first end portion which is at a first axial end of the combustor along an axis of the combustor and a second end portion which is at a second axial end of the combustor along the axis,
- a lead-out port of the air lead-out member is located radially outward of the first end portion,
- an air flow path is formed between the combustor and the outer peripheral cover portion and causes the air led out from the air lead-out member to flow from the first end portion toward the second end portion,
- an inner space is formed between the combustor and the inner peripheral cover portion, and the air flows into the inner space from the air flow path via a communication path provided at the second end portion of the combustor,
- each of the plurality of combustion cylinders is provided with an air flow inlet located at the second end portion of the combustor, the air flow inlet being configured to cause the air which has flowed through the air flow path to flow into each of the upstream portions of the combustion chambers,
- the combustor includes a guide wall portion configured to connect mutually-adjacent combustion cylinders among the plurality of combustion cylinders and guide the air from the air flow path to the inner space via the communication path, and
- at least one through hole is formed in an outer peripheral surface of each of the plurality of combustion cylinders, and opens to the inner space and allows the air in the inner space to flow into a downstream side of each of the combustion chambers.
