The gas-particle two-phase flow in a multistep dust collector has been numerically analysed for the improvement of particle separation efficiency under several typical industrial conditions. Moreover, the calculated results are validated by experiments with a maximum error emax = 4.6%. The results indicate the influence of the geometrical dimensions of the multistep dust collector on particle separation efficiency and pressure drop. The present study proposes an effective approach to optimize a dust collector, which can improve particle separation efficiency at low cost and in a short development cycle.
