Flue dust becomes blast furnace fuel - Swerim

By recirculating flue dust as fuel in the blast furnace, both raw-material costs and environmental impact can be reduced. The method is now used at SSAB in Oxelösund. The idea of using blast furnace dust and sludge as a fuel supplement in the blast furnace was conceived as early as the late 1990s. Flue dust is a residual product from iron production, containing fine-grained
