RADIALLY STAGED LOW EMISSION CAN-ANNULAR COMBUSTOR ABSTRACT 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, addi- tional air may be introduced at the upstream end of the combus- tor 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.
