Uni-flow cyclone dust collector is applied to the separation of particles from air and gases. This equipment could not be expected a high collection efficiency. So in this report, effect of secondary jet was investigated to promote separation efficiency. And its collection efficiency and the pressure drop depended on the velocity of secondary jet as a variable were measured. Velocity V_2 of secondary jet was determined as 13.7,18.5,23.8,27.0 28.4 (m/s), and velocity V_1 of main flow was determined as 3.0,6.0,9.0,12.0,15.0 (m/s). Therefore in this report, the boss diameter was Db=47 (mm), the form of guide vane was plate type of fixed guide vane. and dust was used Fly-Ash, the average particle diameter was X_<50>=5.57 (μ m). and the dust was measured by Andreasen pipette method, This experiment was acted the condition.
