摘要
研究了管式炉辐射室燃烧火焰高度对辐射室温度分布和对辐射室传热量占全炉热负荷比例的影响。指出，通过强化燃料燃烧，降低燃烧火焰高度，可以有效地改善辐射室温度分布，降低辐射炉管受热不均匀系数，提高辐射室传热量占全炉热负荷的比例，因而可提高全炉炉管表面平均热强度和加热炉的处理能力。同时列举了对３台管式炉进行“扩能”改造的应用实例。
The influence of combustion flame height in tubular furnace radiant chamber on the temperature distribution of radiant chamber,and the proportion of radiant chamber heat transfer quantiity to whole furnace heat load,are researched.By means of strengthening the fuel combustion,decreasing combustion flame height,can improve effectively the temperature distribution in radiant chamber,and increasing the proportion of radiant chamber heat transfer quantity to whole furnace heat load.So that the tube surface heat strength of whole furnace,and the processing capacity can be increased. Three applicated examples of tubular furnace“extending energy”reconstruction are listed.
