普锐特冶金技术(Primetals Technologies)获得中国钢铁企业——山东钢铁股份有限公司(山钢)订单,将为其日照烧结厂新建一套选择性废气循环(SWGR)系统。此系统已在奥地利、韩国和中国台湾成功投产,对减少环境排放和降低生产成本起到了积极作用。这是普锐特冶金技术在中国大陆获得的第一份此类先进的环保方案订单。这套SWGR系统的废气循环率高达40%,可将废气向大气的排放量减少770 000 m3/h。另外,烧结工艺的焦炭消耗量可减少约5%。
Primetals Technologies’ orders for a Chinese steelmaker, Shandong Iron & Steel Co., Ltd. (SSC), will set up a new set of selective exhaust gas recirculation (SWGR) systems for its Rizhao sintering plant. The system has been successfully put into operation in Austria, South Korea and Taiwan, China, which has played a positive role in reducing environmental emissions and reducing production costs. This is the first such advanced environmental protection program order that Primetals obtained in mainland China. The SWGR system has an exhaust gas recirculation rate of up to 40%, reducing exhaust emissions to the atmosphere by 770,000 m3 / h. In addition, the coke consumption of the sintering process can be reduced by about 5%.
