Abstract: An object of the present invention is to achieve lower NOx combustion in response to the increasingly intensified NOx regulations for burners. The present invention provides a low nitrogen oxides generating combustion method and apparatus which utilizes effective self-induced exhaust gas recirculation before the initiation of the combustion of diffusion flames, or allows part of the combustion gas to be entrained by auxiliary fuel flow, air flow and fuel flow before the formation of the diffusion flames to further intensify the recirculation flow of the combustion gas by the diffusion flames or, in addition, which can achieve rich and lean combustion in the diffusion flames for decreasing the generation of NOx by a combination of these measures, and which are excellent in flame stability even in a low temperature atmosphere.
