Abstract
A combustor includes a combustion tube having a cylindrical shape with a combustion space where fuel is combusted and including an inlet through which the fuel is introduced, an outlet through which a gas generated when the fuel is combusted is discharged, and a protrusion protruding inward from a wall surface between the inlet and the outlet; an injection unit configured to inject fuel into the combustion tube through the inlet of the combustion tube; and an additional injection unit located on the protrusion of the combustion tube and configured to inject fuel into the combustion tube.
Claims12
A combustor comprising:
- a combustion tube including a wall having a cylindrical shape, an interior of the wall forming a combustion space where first and second fuel is combusted, the wall comprising:
- an inlet through which the first fuel is introduced;
- an outlet through which a gas generated when the first and second fuel is combusted is discharged;
- and
- a protrusion protruding inward in a radial direction of the combustion tube from the wall between the inlet and the outlet in a longitudinal direction of the combustion tube, an outer surface of the protrusion forming an exterior of the combustion tube;
- an injector configured to inject the first fuel into the combustion tube through the inlet of the combustion tube;
- and
- an additional injector located on the protrusion of the combustion tube and configured to inject the second fuel into the combustion tube,
- wherein the protrusion comprises:
- an outer support wall that protrudes in the radial direction toward a central axis of the combustion tube further than a surface of the wall of the combustion tube;
- and
- an inner support wall that protrudes in the radial direction toward the central axis of the combustion tube further than the outer support wall, the additional injector is located on the outer support wall,
- wherein the inner support wall comprises a fuel hole that is formed at a position corresponding to the additional injector and through which the second fuel injected by the additional injector passes to the combustion tube and inner air holes that are formed around the fuel hole, and
- wherein the outer support wall comprises outer air holes that are formed around the additional injector.

- a protrusion protruding inward in a radial direction of the combustion tube from the wall between the inlet and the outlet in a longitudinal direction of the combustion tube, an outer surface of the protrusion forming an exterior of the combustion tube;
- an injector configured to inject the first fuel into the combustion tube through the inlet of the combustion tube;
- and
- an additional injector located on the protrusion of the combustion tube and configured to inject the second fuel into the combustion tube,
- wherein the protrusion comprises:
- a first inclined portion that is inclined toward the inlet of the combustion tube with respect to a surface of the wall of the combustion tube;
- a second inclined portion that is inclined toward the inlet of the combustion tube with respect to the surface of the wall of the combustion tube;
- and
- a connecting portion that extends parallel to the surface of the wall, connects the first inclined portion and the second inclined portion, and allows the additional injector to be located thereon.
