A burnerfor combustion chamber is provided with a cylindrical mixing portionthat mixes air for combustion (oxidizing agent) and fuel in the interior thereof and has one endthat opens to a combustion portion; a spray nozzle (fuel spraying portion)that sprays fuel in the mixing portion, being disposed on another endof the mixing portion; first blowing portsthat introduce the air for combustion to the mixing portionto form a swirling flow with the fuel, being disposed to open to the inner wall of the mixing portion; and second blowing portsthat additionally introduce the air for combustion to the mixing portion, opening in a direction different from the first blowing portsand being disposed further to the other endside of the mixing portionthan the swirling flow. The burner for combustion chamber and combustion method of the present invention can shorten the flame length in the central axial direction by improving the combustion efficiency even during low loading and shorten the overall length of the burner for combustion chamber in the central axial direction.
