Abstract
An object of the invention is to provide a reliable gas turbine combustor that can provide lowered NOx and combustion stability. The gas turbine combustor includes a combustion chamber to which fuel and air are supplied; a first burner located on the upstream side of the combustion chamber, the first burner jetting fuel into the combustion chamber and jetting air into the combustion chamber in a swirling manner; a plurality of second burners arranged around the first burner and supplying a premixed gas of air and fuel to the combustion chamber; an annular bulkhead disposed between the first burner and the second burners and having an inclined surface formed to broaden toward the downstream side of the combustion chamber; and a plurality of air jet ports formed in the inclined surface of the annular bulkhead and adapted to jet air into the combustion chamber.
