摘　　要：本文通过对铁前系统碳素流和能量流进行分析,并基于碳素平衡原理,构建工序层级和铁前系统层级的碳素流输入-输出模型,得出焦化工序的煤气燃烧、烧结工序的固体燃料和点火煤气消耗、炼铁工序焦炭和喷煤消耗的碳排放潜力最大,同时指出改变铁前系统能源结构和重视高炉煤气和焦炉煤气的回收与低碳化利用以及开发节能新技术是解决铁前系统CO_(2)排放问题的重要措施。The input-output model of carbon flow at the process level and pre-iron system level is constructed based on the analysis on carbon flow and energy flow in the pre-iron system and the principle of carbon balance;it is concluded that the carbon emission potential of gas combustion in the coking process,solid fuel and ignition gas consumption in the sintering process,coke and coal injection consumption in the iron-making process is the greatest,while it is also pointed out that changing the energy structure of the pre-iron system and paying attention to the recovery and low carbon utilization of blast furnace gas and coke oven gas as well as developing new energy-saving technologies are important measures to solve the problem of CO_(2) emissions in the pre-iron system.
