The circumferential distribution characteristics of airflow in bustle pipe and each tuyere have been simulated and researched through establishing mathematical model of blast furnace (BF) hot blast systems. The disputes on the circumferential distribution characteristics of airflow in bustle pipe at home and abroad were settled. The results show that, under the premise of uniform pressure distribution in hearth and tuyere section area, except that of the nearest ones, the velocity of airflow in these tuyeres which are near to the main pipe is lower than those far away from the main pipe because of the existence of vortex. However, both the fluctuation range of all tuyeres’ air velocity and its influence on tuyere raceway depth are small and can be ignored.
