已知焦比400kg/t·Fe,煤比150kg/t·Fe,焦炭中含H2有机0.4%,挥

  焦碳中H2(不含CH4):H2焦=[H2有+H2挥]K×22.4/2=20.61m3

  煤粉中H2(不含CH4):H2焦=[H2有+(2/18)×H2O]G×22.4/2=34.91m3

  风中H2:f=12/8=1.5%

  H2风=V风f=21.35m3

  ΣH2=20.64+34.91+21.35=76.87m3

  进入CH4:H2CH4=(2002×0.05%-400×0.03%×22.4/16)×2=1.67m3

  2002×1.6%=Σ(1-η)-H2CH4

  η=0.56
