摘　　要：空载状态下,通过对两种外循环型分解炉系统的阻力特性进行冷模实验研究,得出结论:分解炉截面风速为6.0～8.0m/s时,卧式旋风筒的压力损失约为80～200Pa,旋流分离器的压力损失约为600～1180Pa;外循环式Ⅰ型分解炉系统中"分解炉+卧式旋风筒"的压力损失比Ⅱ型外循环分解炉系统中"分解炉+旋流分离器"的压力损失约低300～600Pa,从而具有较好的阻力特性。Under pure gas flow condition, the pressure drop for two recirculating calciner systems is studied by a cold experiment. The result shows that when the cross-section gas velocity of calciner ranges 6.0-8.0 m/s, the pressure drop of horizontal cyclone separator varies in 80-200 Pa, and the pressure drop of whirl separator is around 600-1180 Pa. The pressure drop for I-recirculating calciner system （calciner and horizontal cyclone separator） is lower than 11-recirculating calciner system （calciner and whirl separator） about 300 -600 Pa,and then the pressure drop property of the former is better.
