摘要中国钢铁行业的节能工作经历了单体设备节能、系统节能阶段和重大节能技术普及阶段,进入到现在的能量流网络化运行、提升能源转换功能阶段,取得了显著成就。钢铁行业面临的节能减排形势越来越严峻,近年来吨钢综合能耗虽然仍在进一步降低,但降幅已经很小,甚至有的年度略有回升。在当前的理论、技术条件下,节能空间越来越小已是不争的事实,准确判断节能的可能性及其潜力十分重要。铁前系统是钢铁制造流程的重点耗能环节,以铁前系统能耗分析为例,提出了理论最小能耗、基准能耗的概念,结合工厂实践,给出了理想工况、基准工况确定的依据及理论最小能耗和基准能耗计算方法,并计算了焦化工序、烧结工序和炼铁工序理论最小能耗和基准能耗。对理论最小能耗与基准能耗、实际能耗与基准能耗进行对比分析,在分析理想工况与基准工况、实际工况与基准工况差异的基础上,分别提出了焦化工序、烧结工序和炼铁工序的节能措施与节能方向;应用系统节能理论的e-p分析法,从铁前系统结构、设备规模、原燃料条件及节能技术应用与能量流网络等方面分析了铁前系统影响因素的影响规律,提出了铁前系统节能措施与方向,研究结果可为合理评估钢铁行业铁前系统节能潜力提供理论支撑。

Abstract：The energy conservation progress of steel industry in China has gone through several stages, such as single equipment energy conservation, system energy conservation and the popularization of major energy-saving technologies,to the current stage of energy flow network operation and improving energy conversion functions. The energy conservation of steel industry in China has made remarkable achievements. The energy conservation and emission reduction situation faced by the steel industry is becoming increasingly severe. In recent years, although the comprehensive energy consumption per ton of steel has still been reduced, the decrease has been very small, and even rebounded slightly in some years. Under the current theory and technologies, it is an obvious fact that the energy saving potential is decreasing, and it is very important to accurately determine the possibility and potential of energy saving. The pre-ironmaking system is the most significant energy consumption system of the steel manufactory process. Therefore, the pre-ironmaking system energy consumption is analyzed as an example, and the concepts of minimum energy consumption and standard energy consumption are proposed. Based on factory practice, the basis for determining ideal operating condition and standard operating condition, as well as the calculation method of theoretical minimum energy consumption and standard energy consumption are provided. The theoretical minimum energy consumption and standard energy consumption, as well as the actual energy consumption and standard energy consumption, are comparatively analyzed. Based on the analysis of the differences between ideal operating condition and standard operating condition, as well as between actual operating condition and standard operating condition, the ways and directions for energy saving for the coking process, sintering process, and iron-making process are provided respectively; Using the e-p analysis method under the theory of system energy saving, the influencing factors of the pre-ironmaking system, such as the system structure, the equipments scale, the raw material and fuel conditions, the energy-saving technology application, and the energy flow network are analyzed; and the measures and directions of energy conservation are proposed. The research results can provide theoretical support for the reasonable evaluation of the energy-saving potential of the pre-ironmaking system in the steel industry.

Key words： pre-ironmaking system minimum energy consumption energy saving evaluation ideal operation condition standard operation condition
