对钢铁联合企业电力模型的分析研究

电力是钢铁企业生产中的重要能源,对整个流程的作业举足轻重.建立了4种钢铁企业的电力和蒸汽发电技术的模型,应用投入产出法对这些动力设备转换模式的模型进行了能源输入、电输出量,蒸汽轮机、燃气轮机、燃煤锅炉余热回收率分析,结合实际的数据对3家典型钢铁企业的电转换率、余热余能回收率和整体转换效率进行了比较,并对这些模型进行了探讨.这些模型的建立对钢铁企业的电力生产具有重要意义.

Research on Models of Power Production in Integrated Iron and Steel Factory

Electricity is an important energy in the production of iron & steel factory, which plays a decisive role in the whole process. This paper presents four kinds of models of steam generation technologies in integrated iron and steel industries. Energy inputs, electricity outputs, recovered waste heat efficiencies of boilers, steam turbines, gas turbines and coal-fired of the models were analyzed by using input-output method. Electric conversion, waste heat recovery and overall conversion efficiencies were compared with the actual data of three typical iron and steel enterprises. The models were discussed. And it is found that these established models have important guiding significance for power production in iron and steel enterprise.
