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.

Claim (Index 6):
The combustor of  claim 1 , wherein the combustion space of the combustion tube is divided into a first zone that is an upstream region where the fuel injected by the injection unit is combusted, collides with the fuel injected by the additional injection unit and air injected through the protrusion, and primarily recirculates toward the inlet, and a second zone that is a region where the fuel injected by the additional injection unit proceeds to a position downstream of the first zone, is combusted, and secondarily recirculates toward the inlet.
