某高炉焦比420kg/t,煤比120kg/t,C焦=85.23%,C煤=80.0%;石

  (1)C气化=420×0.8523+120×0.8+24.5×0.4293×12/44-45=411.84kg/t

  V煤气=1.8667×411.84/(0.2370+0.1818+0.006)=1810m3/t

  (2)V风=1810×0.5623/[(1-0.02)×(1-0.21)]=1315m3/t

  (3)1kgC耗风v风=0.933/(0.21×0.98+.0.5×0.02)=4.325m3/kgC

  C风=1315/4.325=304.05kg/t

  C燃=420×0.8523+120×0.8=453.97kg/t

  则:燃烧率=304.05/453.97=0.67或67%

  (4)CdFe=C气化-C风-CdSi,Mn,P,S-1.5C熔-C焦挥

  C熔=24.5×0.4293×12/44=2.87kg/t

  CdSi,Mn,P,S=5.2×24/28+2.9×12/55+1.0×60/62+400×0.008×12/32=7.26kg/t

  则:CdFe=411.84-304.05-7.26-1.5×2.87=96.22kg/t

  rd=(96.22×56/12)/945.6=0.475
