Future Works

The target of the future research will be the practical application that is extended from the results of present experimental study. Because the NOx

emission increased sharply as the experimental scale became greater, so how to reduce NOx effectively in the future real scale test is a challenging task. The industrial applications of oxygen-enhanced combustion are major in the high temperature environments, such as aluminum remelting furnace, incinerator, glass melting furnace, ladle furnace and so on. The oxygen concentrations in these applications are often higher or pure oxygen.

However, if the existent combustion system wants to use higher oxygen or pure oxygen combustion, the burner and furnace body have to be retrofit substantially due to potential problems, like heat transfer, flame structure, refractory damage and so on. It will limit the applications of oxygen-enhanced combustion. Some researches, Dalton A.I. et al. [3] and Joshi S.V. et al. [4], indicate that many conventional air/fuel burners can be adapted for low-level oxygen enrichment, but the characteristics of low-level oxygen enrichment using on air/fuel combustion system do not study detail yet. Therefore, this is a practical problem, on which the future extension of this work can focus.
