| Abstract: | The three dimensional two phase flow and heat transfer model in the annular gap scrubber of converter gas was proposed,and the corresponding numerical computations were performed for a series of operation conditions.The numerical computed results revealed the two phase flow characteristics and the effects of operation conditions such as gas flow rate,shift displacement of the scrubber cone and the ratio of water/gas on the pressure drop of the annular gap scrubber.Based on the computed results,the effect disciplinarian of different operation conditions on the pressure drop was investigated and the corresponding empiristic criterion was obtained. |
