| Abstract: | In this paper the mechanism of the soot formation and oxidation in the conventional combustion were summarized. The effect of flow field on soot formation and emission was introduced. On the base of the mechanism mentioned above, the characteristics of soot formation and oxidation in high temperature air combustion were analyzed. The distribution of oxidant concentration plays important role in reducing NOX formation and soot emission in high temperature air combustion. Then the technical measures to enhance soot oxidation in high tempera- ture air combustion were discussed. All the analyses would provide theoretical basis to improving this new technology. |
