|
摘要
针对钢铁制造流程能源结构特点,在解析流程中能量转换过程的基础上,提出了钢铁制造流程煤基能量系统的概念,并对煤基能量及煤基能量系统进行了界定。通过定量与定性分析,研究了煤基能量在钢铁制造流程中的转化与耗散规律。在系统效率分析的基础上,指出钢铁制造流程能量流的核心是煤的转换与二次能源的回收利用问题,当前实现煤气资源与余热资源的高效回收利用是提升钢铁制造流程系统能源效率的关键。在"冶金流程工程学"等理论的指引下,提出了实现钢铁制造流程煤基能量系统集成优化及高效运行的主要原则,并通过开展建模与实践研究,探索了以系统优化方法优化能量流网络、构建高效钢-电联产运行模式的可行性。
Based on the energy composition structure characteristics of the steel manufacturing process and the analysis of the energy conversion process,the concept of coal-based energy system for the steel manufacturing process was proposed,and the coal-based energy and coal-based energy system were defined in the current work. Through quantitative and qualitative analysis,the law of transformation and dissipation of coal-based energy in the steel manufacturing process was studied. Based on the analysis of the system energy flow efficiency,it was pointed out that the cores of energy flow in the steel manufacturing process were the conversion of coal and the recycling of the secondary energy,and the efficient utilization of gas resources and waste heat resources was the key to improve the energy system efficiency of the steel manufacturing process. Under the guidance of "metallurgical process engineering theory",the main principles for achieving the integrated optimization and the efficient operation of coal-based energy system in the steel manufacturing process were proposed.Through the modeling research and the practice study,the feasibility of the energy flow network optimization and the efficient steel-electric CO production mode construction was explored based on system optimization methods.
