An experimental equipment of centrifugal seal was designed for the dynamic seal between the basis and the gas outlet pipe of high gravity bed. With the air and water system, the air leakage flow rate was investigated with the changing of the inside pressure. The results indicated that the centrifugal seal can resist 25 kPa critical pressure drop under 1600 r/min rotational speed. Below the critical pressure, the air leakage flow rate was less than 0.2 L/h. The critical pressure drop of CFD simulation was in good agreement with the experimental data.
