Abstract:
The steel industry in Japan has continuously challenged the development of energy saving technologies for achieving substantial reductions in CO2 emission for the past several decades. This report describes, firstly, typical Japanese energy saving technologies, such as TRT for the blast furnace, CDQ for the coke oven and the regenerative burner system for the heating furnace, which were developed and are now standard Japanese technologies in the steel works. Secondly, it explains advanced new heat recovery systems which have been developed such as the thermoelectric generation (TEG) system, which uses the waste heat of the continuous caster, and a system for recovery of heat from hot slag in the steelmaking process. Finally, the concluding remarks discuss current and future studies for the use of waste heat in the steel works that should be developed, such as heat storage systems and control systems for heat supply-and-demand management not only for the steel works, but also for linkage with other industries in order to realize cascade use of energy.
