在大型钢铁企业中,燃气是钢铁企业重要的副产品和主要燃料。就我国钢铁企业而言,能源费用是企业成本高的主要因素,能源的浪费直接关系着钢铁企业成本的高低,因此燃气的综合利用对发展钢铁生产、降低能源消耗和改善环境都有重要的意义。在全面分析河北某钢铁公司燃气系统状况的基础上,建立燃气系统的动态模型,综合气柜安全、用户需求和燃气放散率等实际情况制定燃气系统的调度目标,在此动态模型和调度目标的基础上,结合实际调度经验提出燃气系统的调度方案。通过这个调度方案能使企业燃气的供需平衡达到相对良好的状态,有效地实现节能减排、降低成本,提高了企业经济和社会效益,对大型工业企业煤气的合理分配及优化利用起到指导作用。
In large iron and steel enterprises, gas is an important by-product of steel companies and the main fuel. As far as the iron and steel enterprises in our country are concerned, the energy cost is the main factor of the high cost of the enterprise. The waste of energy is directly related to the cost of the iron and steel enterprises. Therefore, the comprehensive utilization of gas has important significance for the development of steel production, energy consumption and environment improvement. . Based on a comprehensive analysis of the gas system status of a steel company in Hebei Province, a dynamic model of the gas system is established. Based on the actual situation of gas tank safety, user demand and gas release rate, a gas system scheduling goal is formulated. In this dynamic model and the scheduling target Based on the practical dispatch experience, the gas system scheduling scheme is proposed. Through this scheduling scheme, the balance between supply and demand of gas can be relatively well-balanced, energy saving and emission reduction can be effectively achieved, the cost can be reduced, the economic and social benefits of the enterprise can be enhanced, and the rational distribution and optimal utilization of gas in large industrial enterprises can be instructed .
