【摘要】：通過納入副產(chǎn)品流向和流量,使拓展后的企業(yè)投入產(chǎn)出模型能夠更全面地反映生產(chǎn)流程中各種物質流和能流的相互作用,也能更準確求出各產(chǎn)品的能值和總能耗.在此基礎上,結合敏感性分析,建立了最終需求量和技術系數(shù)兩類因素變化對總能耗影響的數(shù)學關系,從而找到工業(yè)生產(chǎn)流程中影響能耗最關鍵的因素.計算分析湘鋼的產(chǎn)品能值和總能耗結果表明:總能耗的90%以上來源于化石燃料,而不足10%來源于外購物料的上游能耗;副產(chǎn)品回收利用能減少62.5%的總能耗;焦爐對洗精煤的單耗、高爐焦比、1#轉爐的鐵水單耗、含鐵物流的利用效率和高爐的技術優(yōu)化(燒結礦單耗和煤氣產(chǎn)率)對能耗影響最為顯著.
[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.
