A burner construction in which staging of combustion is obtained by a primary pressure-atomizing nozzle having a low spray angle to maintain combustion within a central core of the combustor, and a secondary fuel aerating nozzle delivering fuel in a hollow cone configuration surrounding the primary fuel spray for combustion in an annulus between the central core and the wall of the combustor. Although most of the air for primary combustion is supplied with the fuel nozzle, additional air may be introduced at the upstream end of the combustor by high penetration jets that enter the central core and additional air for secondary combustion is introduced by one or more rows of holes in the combustor wall near the upstream end.

A burner construction including: a burner duct; a can in said duct having an upstream end cap; a fuel nozzle in said cap having: means for delivering primary fuel in a low angle spray for idle and low power, other means surrounding said first means for delivering secondary fuel in a hollow cone surrounding and spaced from the low angle spray for higher power operation with the primary fuel; and a row of axially extending holes in said cap surrounding the nozzle to direct a flow of air axially around the spray of primary fuel.
