通过冷态模拟实验,研究了卡鲁金热风炉喉口至蓄热室间的流场特性、喷口流体的均匀性及蓄热室格子砖阻力特性对流场的影响。结果表明:卡鲁金热风炉流场均匀、稳定、对称性好,空、煤气喷口气流分布比较均匀。在空、煤气分别单吹的情况下,空气喷口的均匀度达到90%以上,煤气喷口的均匀度也接近90%。蓄热室格子砖阻力分布均匀与否对蓄热室流场无明显影响。 Through the cold simulation experiment, the influence of the flow field between the throat and the regenerator, the uniformity of the nozzle fluid and the resistance of the regenerator lattice on the flow field were studied. The results show that the flow field of Karuogu hot air stove is uniform, stable and symmetrical. In the air, the case of single gas blow, the uniformity of the air nozzle reaches more than 90%, the uniformity of the gas nozzle is also close to 90%. The uniform distribution of the resistance of the regenerator lattice did not affect the flow field of the regenerator.
