ABSTRACT:
A combustion liner for a gas turbine combustion apparatus or the like has a head wall and a side wall extending downstream to an outlet for combustion products. A reaction zone is contained within the upstream end of the side wall and a dilution zone downstream. A barrier ring extends inwardly from the side wall to provide a constricted path between the zones. Combustion air is admitted from a cluster of nozzles in the head wall and a ring of nozzles extending forwardly from the side wall. Each nozzle in the head wall is axially aligned with one of the nozzles in the side wall so that air jets entering into the combustion zone through each such pair of nozzles impinge to create a high degree of turbulence. Fuel is jetted against a spatter plate in each nozzle in the head wall so that the fuel is atomized and entrained by the air flowing through the head wall air nozzle.
