ABSTRACT OF THE DISCLOSURE An apparatus for cleaning the exhaust gas of a high- pressure blast furnace comprises an optional coarse-particle separa- tor, a prewasher and a differential-pressure annular gap washer tra- versed in succession by the gases. The exhaust gases can be passed through a main duct provided with an expansion turbine or through a bypass duct around the expansion turbine. The expansion turbine unit controls the back pressure at the blast furnace while a separate con- trol circuit is provided to operate the differential-pressure washer with optimum efficiency. A quick-closing valve in the turbine-supply line and a quick-opening valve in the bypass line permits rapid switchover, a pressure-control valve in the bypass line maintaining a constant backpressure at the blast furnace when the expansion tur- bine unit is shut down.
