摘要
运用CFD软件对均热炉的燃烧进行了数值模拟,分析了燃气组成变化对均热炉燃烧温度、烟气辐射强度、炉内流场和炉内温度场均匀性的影响。在理论分析的基础上对均热炉进行了实际测试。不同燃气组成,在热值相近或相差较大的情况下对均热炉的热效率均有很大影响,均热炉仍有节能减排潜力。
The numerical simulation of combustion in soaking furnace is performed by CFD software. The influence of change in gas composition on combustion temperature, radiation intensity of flue gas and uniformity of flow field and temperature field in soaking furnace is analyzed. The actual testing of soaking furnace is performed based on theoretical analysis. When the heating values are similar or different considerably, the influence of gases with different compositions on the thermal efficiency of soaking furnace is great. The soaking furnace has still a potential in energy saving and emission reduction.
