Energy Efficiency Analysis and Promotion Countermeasure in Iron and Steel Enterprises

Abstract

Facing the fierce competition in the domestic and abroad, it is a common task for all the steel enterprise to search for their way to survive. Steel industry is highly dependent on resources, and high energy consumption, high emissions. Improvement of energy efficiency is one way to get rid of the predicament and make Chinese steel industry from large to strong. This also meets the international trends of the energy conservation and emission reduction, green low-carbon, circular economy. Matter flow in iron and steel enterprise includes material flow, energy flow and emission flow. Energy flow drives the material flow in steelmaking process and brings out the emission flow at the same time (forming environmental problems). It is clear that energy flow plays an important intermediary role in the material flow. Energy management includes energy production, energy transfer and conversion, rational use of energy, which core indicator is energy efficiency. The energy efficiency of iron and steel enterprise is highly related to material flow structure and enterprise benefit. In this paper, by analyzing the energy efficiency of iron and steel enterprises, the specific direction and path of improving energy efficiency of iron and steel enterprises are put forward, including strengthen the coordination of energy flow material and flow emission flow, and enhanced waste heat energy utilization.
