1.前言 我厂在鞍钢公司统一规划下,于1979年10月到1982年2月间先后对厂属四座连续加热炉进行改造。除探讨了合理炉型,综合节能措施外,都优先考虑了以回收烟气余热,提高助燃空气温度为重点的燃烧系统的改造,选择了适用的余热回收装置和合理的燃烧器,并具体分析了换热器的选型、安装和保护性措施等。经过近几年的实践证明,回收余热预热助燃空气,以空气物理热
1. Foreword I plant in the unified planning Anshan Iron and Steel Company, from October 1979 to February 1982 successively plant on the four continuous heating furnace transformation. In addition to the reasonable furnace type and comprehensive energy-saving measures, the combustion system with the focus on waste heat recovery and combustion air temperature recovery is prioritized, the suitable waste heat recovery device and reasonable burner are selected and analyzed in detail The heat exchanger selection, installation and protective measures. After several years of practice has proved that the recovery of waste heat preheat combustion air to physical heat of the air
