A combination burner, consisting of a main swirl burner in which gases of very low calorific value such as industrial waste gases can be burned and a secondary burner for ignition and support of the main burner in which fuels with high calorific value such as natural gas or fuel oil can be burned, is presented. The combination burner is designed so that the flame of the secondary burner (upstream of and coaxial with the waste gas burner) will have stability, ignition capability and invulnerability to quenching even in open contact with the swirling waste gas and even when the composition of the waste gas becomes temporarily insufficient to sustain combustion. This is accomplished by aerodynamics utilizing a low swirl in the secondary burner, as compared to the higher swirl of the waste gas burner to sufficiently stabilize the flame of the secondary burner by recirculation but providing an outward flow pattern which forms an effective barrier for the reverse vortex flow in the waste gas swirl chamber.
