摘　　要：在不同温度、风速和固气比条件下对旋风预热器的压降进行了测试。结果表明压降随着温度的升高,先增大后减小,大约在200～400℃之间出现最大值;压降随风速的提高而增大;压降随着固气比的增大先减小后增大,大部分在Z=1.5～2.0之间出现最小值。The pressure drop of the cyclone preheater was measured in different temperature,gas velocity and solid-gas ratio.The results showed that the pressure drop increased with the gas temperature increasing till to a maximum value approximately at the gas temperature of 200 ~400℃,then the pressure drop decreased with the gas temperature further increasing.The pressure drop increased with the gas velocity increasing.The pressure drop decreased gradually with the solid-gas ratio increasing,and mostly reached a minimum value between Z=1.5 and Z=2.0.Across this point,the pressure drop increased with the solid-gas ratio further increasing.
