Combustor of a gas turbine engine

Abstract

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; 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 an annular separation portion disposed between a downstream end of the fuel spray portion and a downstream end of the pre-mixture supply portion so as to separate the diffusion combustion region and the pre-mixture combustion region from each other.
