简答题已知一分析煤样的Qb,ad=23854J/g,Had=2.95%,Mad=2.52%,Mar=6.5%,St,ad=0.64%,求该煤样的Qgr,d和Qnet,v,ar?(α=0.0012)
  • Qgr,ad=Qb,ad-(94.1St,ad+αQb,ad)=23854-(94.1×0.64+0.0012×23854)=23765J/g≈23.76MJ/Kg
    Qgr,d=Qgr,ad/(100-Mad)=23765/(100-2.52)=24379J/g24.38MJ/Kg
    Qnet,v,ar=(Qgr,ad-206Had)×【(100-Mar)/(100-Mad)】-23Mar=(23765-206×2.95)×【(100-6.5)/(100-2.52)】-23×6.5=22063J/g≈22.06MJ/Kg。
