德国HKM(Hüttenwerke Krupp Mannesmann)厂采用了具备低排放和能源优化的烧结工艺(LEEP),其废气循环利用率达到50%左右,从而使废气排放量明显下降。循环利用的气体还为烧结过程供热,可使固体燃料消耗降低大约
The German Hüttenwerke Krupp Mannesmann plant uses a low-emission and energy-optimized sintering process (LEEP) with an exhaust gas recirculation rate of around 50%, resulting in a significant reduction in emissions. Recycled gas also heats the sintering process, reducing solid fuel consumption by about
