摘　　要：摘要在电炉炼钢厂，废气余热回收具有极大潜力。根据低端废气管温度和对稀释空气的控制，大部分这种能量都可以回收。根据技术和截然不同的观点，这里的蒸汽缓冲不是问题。几乎在任何情况下，都可避免对过热蒸汽的需要，在经济上更有利于发电。In EAF steelmaking the off-gas provides the biggest potential for heat recovery. Depending on the temperature at the lower end of the off-gas duct and the control of dilution air,a big share of this energy content can be recovered. Depending on technology and contradictory to widespread opinion, steam buffering is not an issue here. In almost any case, it is possible to avoid the need for superheated steam and it is economically more favourable to generate power.
