- 简答题已知烧结矿和块矿含铁分别为47.55%,45.50%,熟料率95%,焦批6.0t,负荷3.8,料速10批/h,喷吹煤粉12.5t/h,试计算焦比、煤比、燃料比和综合焦比?(置换比0.7,Fe元素进入生铁98.4%,生铁含Fe92%)
-
矿石批重=6.0³3.8=22.8t
其中烧结矿22.8³95%=21.66t
块矿22.8³5%=1.14t
每批出铁=(21.66³47.55%+1.14³45.50%)³98.4%/92%=11.57t
焦比=6.0/11.57=0.519t/t²Fe
煤比=12.5/10/11.57=0.108t/t
燃料比=0.519+0.018=0.627t/t
综合焦比=0.519+0.108³0.7=0.595t/t
该炉焦比519kg/t,煤比108kg/t,燃料比629kg/t,综合焦比595kg/t。 关注下方微信公众号,在线模考后查看
