【摘要】 作为钢铁企业重要的二次能源,副产煤气的生产、消耗与钢铁生产有着密切联系。煤气的供需不平衡容易对生产造成影响,因此对副产煤气优化调度的研究将有效改善煤气的供需关系,降低吨钢消耗,提高能源效率,对企业的节能降耗、绿色发展具有重要意义。本文将钢铁企业煤气系统作为研究对象,在前人研究的基础上,对煤气系统的优化调度问题深入研究。通过对煤气系统的分析,建立了煤气优化调度模型,并采用MILP方法完成了富余煤气在煤气柜和锅炉之间的分配。结果表明:模型优化了钢铁企业对于富余煤气的分配,增加了发电量,提高了能源的利用效率。更多还原

【Abstract】 As an important secondary energy source for steel companies,the production and consumption of by-product gas is closely related to steel production.The imbalance of supply and demand of gas is easy to affect production.Therefore,the research on the optimization of by-product gas will effectively improve the supply and demand relationship of gas,reduce the consumption of steel per ton,improve energy efficiency,and is of great significance to energy conservation and green development of enterprises.This paper takes the steel enterprise gas system as the research object,and on the basis of previous studies,it studies the optimization of the gas system.Through the analysis of the gas system,the gas optimization scheduling model was established,and the distribution of surplus gas between the gas cabinet and the boiler was completed by the MILP method.The results show that the model optimizes the distribution of surplus gas by steel companies,increases power generation,and improves energy efficiency.更多还原
