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 effects of the combustion flame height of the tube furnace on the temperature distribution of the radiation chamber and the heat transfer of the radiation chamber to the heat load of the furnace were studied. It is pointed out that by intensifying the fuel combustion and reducing the height of the combustion flame, the temperature distribution in the radiation chamber can be effectively improved, the non-uniform heating coefficient of the radiant furnace tube can be reduced, and the ratio of heat transfer in the radiant chamber to the heat load in the radiant furnace can be increased. Average surface hot strength and furnace handling capacity. At the same time, lists the three tube furnace “expansion” application examples.
