Blast Furnace Gas Cleaning and Recycle Systems

Recent developments in Blast Furnace operation, characterised by long campaign life combined with ever increasing productivity and high rates of fuel injection, require high efficiency top gas cleaning equipment to cope with the changes in top gas composition, dust loading, pressure and temperature fluctuations and match the campaign life of the furnace. The annular gap scrubber has major advantages in comparison with other venturi scrubbers.

Danieli Corus has engineered and installed over 120 gas cleaning systems of the annular gap scrubber type, some of which including an expansion turbine.
