摘要:
采用RNGκ-ε湍流模型、非预混(PDF)燃烧模型以及各向异性散射的P-1辐射传热模型,对双预热蓄热式环形炉内的火焰特性进行了模拟分析,比较了不同空气喷入角和不同预热温度对火焰特性的影响.结果表明:空气喷入角为5°时火焰体积较大,但燃烧不完全损失较多;喷入角为30°、40°时火焰体积相对较小,最高燃烧温度较高;喷入角为10°～20°时综合特性较好.预热温度的增加提高了燃烧稳定性,使得最高燃烧温度和燃烧室平均温度明显增高.
Abstract:

The flame characteristics in the double preheated regenerative annular furnace were simulated by using the RNGκ-ε turbulence model, the non-premixed (PDF) combustion model and the anisotropically scattered P-1 radiation heat transfer model, and the effects of different air injection angles and different preheating temperatures on the flame characteristics were compared. The results show that the volume of flame is larger when the air injection angle is 5°, but the loss of incomplete combustion is more. When the injection angle is 30° and 40°, the flame volume is relatively small, and the maximum combustion temperature is high. When the injection angle is 10°~20°, the comprehensive characteristics are better. The increase of preheating temperature improves the combustion stability, so that the maximum combustion temperature and the average combustion chamber temperature increase significantly.
