摘　　要：分析了火焰切换式蓄热燃烧系统的优点与不足,提出了有效补偿这些不足并可实现蓄热连续燃烧的高温空气燃烧技术。并以此技术为基础开发出了单台燃烧器可连续燃烧的自蓄热高温空气燃烧装置。采用了中科院广州能源研究所的蓄热燃烧专用高温切换阀专利技术,可以实现高温烟气余热的"极限稳定回收"以及高温贫氧状态下的"连续燃烧"。进一步探讨了此项技术在熔铝炉及其他加热炉上的应用,扩大了蓄热燃烧的应用领域。This work is concerned with consecutive combustion in the field of high temperature air combustion on the basis of analyzing the advantages and shortcomings of alternative HTAC systems.The attention is focused on the technology of consecutive combustion which overcomes the shortcomings of alternative flames of HTAC system.A new consecutive combustion form has been proposed here and a new self-regenerative burner invented by us has been introduced too.A patient valve is used in this new burning system.It can burn continually in the HTAC mode with the low NOX result.The application of this technology in melting aluminum and other industrial furnaces is also dicussed.
