Abstract:

With the structure of tubular furnace energy saving as a starting point，the research on energy saving of tubular furnace burner，radiation chamber，convection chamber and heat recovery is reviewed including the restructuring of burner and radiation chamber，optimization of soot-blowing development of new decoking  technology， new air preheater，and new radiant tubes. Enhancement of radiation heat transfer and heat recovery can effectivelylower exhaust gas temperature，and improve heating efficiency，contributing to higher furnace energy efficiency． Finally，future research on energy-saving of tubular furnace study is proposed.

摘要：

以管式加热炉主要结构的节能为出发点，从改造燃烧器及辐射室结构、优化吹灰技术、研发新型清焦技术以及研制新型空气预热器和新型辐射炉管等方面，综述了目前管式加热炉燃烧器、辐射室、对流室及余热回收系统的节能效果的研究情况，其中增强辐射传热和余热回收能力可有效降低排烟温度，提高加热炉效率，因此其对于管式加热炉的节能更有效。最后对今后管式加热炉的节能研究提出展望。
