PROBLEM TO BE SOLVED: To provide a combustion system less in NOx and superior in combustion stability by solving problems with high level NOx in the case of a diffusion combustion system and with combustion stability due to backfire in the case of a premixture combustion system, at the same time. SOLUTION: A combustion air flow path is arranged coaxially with a fuel flow on the wall face of a combustion chamber to form a coaxial jet with the fuel flow embraced by an air flow, as a porous coaxial jet with these diffused in number. Herein, a circular collar member is provided at the end of a fuel nozzle to form the air flow path perpendicular to the axis of the fuel flow. COPYRIGHT: (C)2004,JPO
