Coal-based smelting reduction experiments have been carried out using a specially designed reactor to develop a process route for the co-production of liquid iron and a predominantly sulphur-free synthesis gas. Steady state operating conditions of constant bath carbon and temperature were achieved over extended operating periods with continuous additions of dri, iron ore, coal and oxygen into a liquid iron bath. A thermal model describing the pilot-plant operation has achieved close correlation between predicted bath temperature and plant measurements. Thermal balances showing the distribution of energy within the reactor have been developed as an aid to process understanding and to optimise operating techniques. An engineering feasibility study has been carried out detailing the key components of an intermediate-sized works-based demonstration plant producing 5 t/h of liquid iron and up to 8 x 1.0 E3 Nm3/h of synthesis gas for a mixed charge of scrap, iron ore, coal and oxygen. Capital and operating costs have been estimated for the demonstration plant, together with projections for capital and operating costs of a commercial unit producting 50 t/h of liquid iron and 8 x 1.0 E4 Nm3/h of synthesis gas.
