    新钢8#烧结机余热发电运营项目
    工程名称新钢8#烧结机余热发电运营项目
    工程地点江西-新余市-新余区服务领域其他环境工程建设 规模8.2MW/h
    工程投资
    详细信息

         新钢8#烧结机余热发电运营项目位于江西新余钢铁集团烧结厂内,装机规模12MW,设计发电功率8.2MW/h。该项目由长天能环采用EMC(合同能源管理)方式全额投资建设,为国家政策鼓励的环境保护节能减排项目,运营期为8年时间。该项目投产以来,节能减排效果显著,采用梯级给风技术。梯级给风冷却技术是一种新型的配风技术,通过环冷机前部循环风机的变频调节以及环冷机后部鼓风机的启停,增加了前部取热段的冷却风量,使取热段的热量尽可能在前部利用,同时,由于梯级给风,前部的留冷却风量增加,冷风与烧结矿之间的对流换热增强,有效了提高取热段的废气温度,在烧结正常生产的情况下,第一段高温废气的温度可稳定在380℃以上;采用废热梯级利用技术,并与烧结工艺紧密结合,根据烧结厂的实际需要,在前部环冷机余热被余热锅炉充分利用后,将原本直接放散的环冷机后部约200—240℃烟气加热热水供烧结工艺用,原本需要用来加热热水供烧结工艺用的蒸汽做为余热发电的低压汽源,提高了整体余热回收效率,增加了余热发电量。该项目2012年度发电量为5450万度,每年可节约标煤量2.73 万吨,年减排二氧化碳6.82万吨。节能减排效果显著。对钢铁行业烧结工序节能降耗产生了显著的影响,具有显著的经济效益和环保效益。
