蓄热式燃烧系统的最新发展是在蓄热室中使用陶瓷蜂窝作为蓄热介质，将预热空气温度提高到1600 K。通过预热燃烧空气，增加了炉气的加热潜力，并显著降低了燃料消耗。然而，较高的空气温度增加了NO/sub x/形成的可能性。因此，为了将该技术应用于商业用途，强烈要求开发低NO/sub_x/燃烧器。本文介绍了新开发的低NO/sub_x/燃烧器和高性能蜂窝蓄热体。并对高预热空气燃烧的节油效果进行了理论和数值分析。
Recent development of the regenerative combustion system in which ceramic honeycomb is used as a heat storage medium in a regenerator, has raised preheated air temperature up to 1600 K. By preheating the combustion air, the heating potential of the furnace gas is increased and the fuel consumption is reduced dramatically. However, higher air temperature increases the potential of NO/sub x/ formation. Therefore, to apply this technology for commercial use, development of low NO/sub x/ burner is strongly requested. In this paper, newly developed low NO/sub x/ burner as well as the high performance honeycomb regenerator is explained. Also, theoretical and numerical analysis of fuel saving by the high preheated air combustion is discussed.
