高炉热量有效利用系数
utilization coefficient of heatin blast furnace
gao{u reliang youxiao liyong父ishU高炉热量有效利用系数(utilization eoeffi-eient of heat in blast furnaee)高炉炼铁中生产单位生铁的有效热量消耗与热量总收入的比值，即认一Q有效/Q总收入火10。%，是衡量高炉内热量利用程度的指标，可通过高炉热平衡计算得出。热量总收入包括燃料(焦炭和喷吹燃料)中碳氧化放出热量(风口前燃烧和直接还原和间接还原中的氧化)，氢还原氧化物放热和热风带入热量等;有效热量消耗包括氧化物还原，脱硫，碳酸盐分解，铁水和炉渣的焙等(见高炉热平衡)。由于热平衡编制的方法有几种，热量总收入和有效热量消耗计算有差别，因此热量利用系数也略有差别。在现代高炉上按第一种热平衡计算的叭在90%左右，而按第二种热平衡计算的，。在75%~85%。这些数值说明高炉是热量利用很好的冶炼设备。 (王筱留)
