钢铁企业能耗分析模型的建立及应用

Establishment and application of iron and steel enterprise energy consumption analysis model

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。

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 .
