[en] As the flame width of the conventional combustor is narrow, it reduces the quality of the products to be heated by heating them partially. A wide flame combustor can heat the heating region uniformly with fewer combustors. An impinging jet combustor was set up to generate the wide flame and oxygen was used as the oxidizer to increase the radiation heat flux. The results show that a stable oxygen fuel wide flame can be generated using the impinging jets method. The oxygen fuel wide flame changed to a diffusion flame, wide flame, and split flame, respectively, with increasing oxygen inlet velocity. In particular, the oxygen fuel wide flame was found to be highly stable with a wide flame region with the following parameters: fuel 1.0 l/min, oxygen 1.2 l/min, h 0, w 4, and impinging angle 50°.
