Recently, top gas pressure recovery turbine units have been installed in most steelmaking plants for energy saving purpose. In Kokura steel works, a wet axial flow turbine was installed at No. 2BF in March, 1979. This unit has been working satisfactorily and consuming less energy. Furthermore a development was made on the Blast-furnace Gas Dry Cleaning System (BDC) and the wet axial flow turbine was reconstructed. After the small bagfilter test and several other kinds of tests at the pilot BDC unit on the same scale as the new commercial unit, the BDC unit was installed at No. 2BF in Kokura steel works in March, 1982. This unit is working satisfactorily. At the same time the wet axial flow turbine was converted to the dry axial flow turbine. This system resulted in the power increase of about 45% compared with the conventional one.
