Abstract According to modeling theory, a cold model of a largescale regenerative annular heating furnace with scale of 1∶10 was built. Based on the principle of PIV test, with tracing particles,the highspeed camera was adopted to record velocity field. Results indicate that the airflow from burners could not be sucked by the first opposite nozzle on the other side wall,the closer the burner to soaking section,the more difficult the air removing is and gas residence time could be prolonged, and shortcircuit of flue gas could be avoided. The air velocity profile changes greatly in the chamber, the farther the air flow from the nozzle, the less the velocity change is. At a certain angle of the air jet, there are two vortexes at both sides of the burner.The higher the air flow rate,the easier the air flow reaching the opposite wall.
