| 摘要 |
The present invention provides a combustor of a gas turbine engine, including: a fuel spray portion configured to spray a fuel so as to create a diffusion combustion region in a combustion chamber, the fuel spray portion including a fuel atomizing portion configured to atomize the fuel, and a diffusion passage portion disposed downstream of the fuel atomizing portion, the diffusion passage portion having a spreading trumpet-like shape and being configured to diffuse the fuel and the air; a pre-mixture supply portion configured to supply a pre-mixture gas including the fuel and an air so as to create a pre-mixture combustion region in the combustion chamber, the pre-mixture supply portion being positioned concentrically with the fuel spray portion so as to surround the fuel spray portion; and fuel diffusion restraining member disposed on an inner circumferential face of the diffusion passage portion for restraining a diffusion of an injected fuel by separating a stream of the injected fuel away from the inner circumferential face.
