Sleeves (28) are circumferentially spaced from one another about the liner of a combustor body (12) of a dry low NO x combustor. The sleeves carry dilution air into the dilution zone. Cooling air is supplied a venturi (20) to cool the venturi and the cooling air flows into the reaction volume. The dilution air sleeves penetrate sufficiently to thoroughly mix the dilution air with the core of hot gases of combustion and, by vorticity effects caused by the flow past the sleeves, thoroughly mix the generally annular flow of cooling air from the venturi with the hot gases of combustion. The thorough mixing of both the cooling air and dilution air inhibits or minimizes the formation of cold areas or streaks within the reaction volume such that CO to CO2 reactions are not quenched, affording reduced CO emissions.
