Abstract
A method of operating a double dome combustor includes channeling compressed airflow through an inner dome for generating inner combustion gases having an inner reference velocity greater than an outer reference velocity of outer combustion gases generated from compressed airflow channeled through an outer dome, and diffusing the outer and inner combustion gases in outer and inner combustion zones. One double dome combustor effective for practicing the method in accordance with the present invention includes outer and inner combustor liners and domes, with the domes having outer and inner carburetors disposed therein, respectively. The inner carburetors are sized for generating inner combustion gases in the inner combustion zone having an inner reference velocity greater than an outer reference velocity of the outer combustion gases generated in the outer combustion zone. In a preferred embodiment, the combustor includes an annular centerbody which, along with the combustor outer and inner liners, defines diverging outer and inner combustion zones.
