Corus and CENIM have jointly carried out an ECSC D&PP project to demonstrate the feasibility of sustained blast furnace injection of iron and steelmaking by-products, with oil. Two extended production trials have been completed, together with numerous laboratory tests and modelling work. These activities have shown that the major issues relate to the handling and mixing operations. An outline plant design is proposed to achieve efficient recovery and screening of slurry material. Once a satisfactory oil/slurry mix is prepared, it can be transported and injected into the furnace relatively easily and its effect on overall furnace operation is minimal. No evidence was found of raceway problems; no tuyere build-up was observed and no effect on overall furnace permeability was measured. Analysis of off-gas products showed no dioxin or PAH problems, indicating that much higher loadings are feasible, if it is considered desirable to add other by-product arisings. Process modelling indicates that, under current Port Talbot conditions, operating cost savings of approximately 25 p/tHM can be achieved at a by-product/waste oil injection rate of 1 t/h (16 and 9 p/tHM for the by-product and waste oil respectively). This equates to an annual operating cost saving of over GBP 350 000 which, after deducting the injection plant costs, would leave a net saving of at least GBP 1000 000 p.a. Combined with the environmental benefits, this makes a compelling case for by-product injection.
