钢铁企业各种能源的生产、转换和使用直至废气排放的过程构成了钢铁企业的能量流动过程。针对能量流动过程,构造了从一次能源到二次能源产品的生产、转换和使用过程直至废气排放的能量流图;基于能量流图,建立了钢铁企业能量流模型,分析了钢铁生产过程中各种能量流的变化对企业能耗的影响。
The energy flow process in iron and steel enterprise is composed of production, conversion, using of various sorts of energy and waste gas removing. The energy flow diagram from crude energy resources to secondary energy resources and then to gas removing is constructed. The energy flow model is designed based on the energy flow diagram. The influence of the energy flow change on the energy comsuption in iron and steel production process is also discussed.
