钢铁企业能耗分析模型的建立及应用

摘要

China's present energy consumption situation of iron and steel industry was described , the development of energy system model was reviewed , and the establishing and the solving process of in-put-output model were expounded .The multistage input-output method was applied to a company . An index system was set up to evaluate from the perspective of multi -level and comprehensive energy consumption situation of the enterprise .Using the model to evaluate the application results of the com-pany's adopted energy saving technologies , and according to its energy consumption situation propose new energy-saving technology .%叙述了我国钢铁工业能耗现状，回顾了模型化研究能源系统的发展历程，阐述了投入产出模型的建立及求解过程。将多级投入产出法应用到某钢铁企业，建立了评价指标体系，从多层次、全方位的角度来评价企业的能耗情况。通过模型计算对该企业已采用的节能技术的应用成效进行了评估，并根据其能耗情况提出新的节能技术，为企业的节能减排提供参考。
