【摘要】：通过纳入副产品流向和流量,使拓展后的企业投入产出模型能够更全面地反映生产流程中各种物质流和能流的相互作用,也能更准确求出各产品的能值和总能耗.在此基础上,结合敏感性分析,建立了最终需求量和技术系数两类因素变化对总能耗影响的数学关系,从而找到工业生产流程中影响能耗最关键的因素.计算分析湘钢的产品能值和总能耗结果表明:总能耗的90%以上来源于化石燃料,而不足10%来源于外购物料的上游能耗;副产品回收利用能减少62.5%的总能耗;焦炉对洗精煤的单耗、高炉焦比、1#转炉的铁水单耗、含铁物流的利用效率和高炉的技术优化(烧结矿单耗和煤气产率)对能耗影响最为显著.
[Abstract]:By incorporating by-product flow and flow, the expanded enterprise input-output model can reflect the interaction of all kinds of material flow and energy flow in the production process more comprehensively, and more accurately calculate the energy value and total energy consumption of each product. On this basis, combined with sensitivity analysis, the mathematical relationship between the change of final demand and technical coefficient on total energy consumption is established, and the most critical factors affecting energy consumption in industrial production process are found out. The results show that more than 90% of the total energy consumption comes from fossil fuels, while less than 10% comes from the upstream energy consumption of outsourced materials, and the recovery and utilization of by-products can reduce the total energy consumption by 62.5%. The unit consumption of clean coal in coke oven, hot metal consumption in coke ratio converter of blast furnace, the utilization efficiency of iron-containing logistics and the technical optimization of blast furnace (sinter unit consumption and gas yield) have the most significant influence on energy consumption.
