Abstract

A swirl mixer for a fuel nozzle having a mixing duct comprising a center duct and two annular ducts located radially outward therefrom. Each duct has an air inlet and swirling vanes located adjacent thereto. The outlet of the center duct is located entirely within the annular duct located radially outward therefrom, and the airflows within the ducts have significantly different swirl angles tailored to yield low smoke production and high relight stability in a high temperature rise combustor.
