BHP New Zealand Steel operates four rotary kilns for the production of sponge iron through direct reduction of iron ore sands and coal. The process gases contain a high potential of energy which until recently had not been utilized. A new plantfor the thermal utilization of these process gases was developed and installed by Austrian Energy in cooperation with Transfield Power Systems, Australia. The installation is the first plant of its kind in the world. Its four boilers have a total capacity of 252 t/h steam which is used to generate electrical energy for the steelmelting shop.
