The conveyor pipe (3) can thus be cleaned by means of the fluidization gas flow and the propellantflow.
也可以借助流化气流与动力气流清洁输送管道(3)。

Another advantage of the invention is that the fluidization gas flow and the propellantflow are also suitable to transport remains of the material to be conveyed out of the conveyor pipe (3).
本发明的另外一个优点在于，流化气流与动力气流也可将输送管道(3)中的物料残渣传送出来。
