【摘要】：面对残酷的国内外竞争环境,寻求生存之道是所有钢铁企业所面临的共同任务。钢铁工业是高度依赖资源,且高能耗、高排放的行业,提高能源效率是中国钢铁由大转强、摆脱困境的方法之一,这也符合节能减排、绿色低碳、循环经济的国际大趋势。钢铁企业的物质流包括物料流、能源流及排放流。能源流驱动物料流在制造商品钢材的同时产生排放流(形成环境问题),可见能源流在物质流之中起着中介的重大作用。能源管理包括能源制造、能源传输与转换、合理用能,而贯穿能源管理的核心指标是能源效率,钢铁企业的能源效率是与物料流结构、企业效益高度相关的。通过对钢铁企业能源效率的分析,从强化能源流与物料流及排放流的协同、加强余热余能利用等方面提出了钢铁企业提升能源效率的具体方向与路径。
[Abstract]:Facing the cruel competition environment at home and abroad, it is a common task for all iron and steel enterprises to seek the way to survive. Iron and steel industry is a highly resource-dependent, energy-consuming and high-emission industry. Improving energy efficiency is one of the ways to get rid of the predicament of China's iron and steel industry, which is also in line with the international trend of energy saving and emission reduction, green and low carbon, and recycling economy. Material flow in iron and steel enterprises includes material flow, energy flow and emission flow. The energy flow drives the material flow to produce the emission flow at the same time as the commodity steel (forming the environmental problem, it is obvious that the energy flow plays an important role in the medium of the material flow. Energy management includes energy manufacturing, energy transmission and conversion, and rational use of energy. The core index of energy management is energy efficiency. The energy efficiency of iron and steel enterprises is highly related to the structure of material flow and the efficiency of enterprises. Based on the analysis of energy efficiency of iron and steel enterprises, the specific direction and path of improving energy efficiency of iron and steel enterprises are put forward from the aspects of strengthening the coordination of energy flow, material flow and emission flow, and strengthening the utilization of residual heat energy.
