Rational suggestions on energy conservation and consumption reduction for steel enterprises

1. Optimizing the industrial structure of the steel industry

At present, there is a large gap in energy consumption levels among steel companies. The energy consumption per ton of steel of key large and medium-sized steel companies is relatively low and has reached the world's advanced level. level. Many small and medium-sized steel companies still have some iron-making technology and equipment that are old, and there is a big gap between backward indicators and advanced indicators. Eliminating backward production capacity and shutting down old and backward steel equipment is the only way to save energy in the steel industry.

2. Promote mature energy-saving and consumption-reducing technologies and develop new energy-saving technologies

The steel industry has long processes, many processes, high energy consumption, and large space for energy recovery. Accelerate technological transformation and promote the application of energy-saving technologies such as dry coke quenching, integrated coking coal moisture control and air separation, large oxygen-enriched high-efficiency coal injection incineration, blast furnace gas pressure difference power generation, converter dry dust removal and negative energy steelmaking. It is not only necessary to promote existing leading technologies, but also to encourage companies to continue to increase research and development efforts, study new technologies and make full use of waste heat and energy resources.

3. Extend the industrial chain of comprehensive utilization of steel resources

Extend the industrial chain of comprehensive utilization of steel, encourage cooperation between the steel industry and other industries, promote comprehensive utilization, and improve the utilization of surplus coal gas, The recovery and comprehensive utilization of waste heat and pressure, solid waste, and wastewater, combined with industries such as building materials, petrochemicals, and electricity, can help increase social resource utilization, reduce the emission of various pollutants, and achieve multi-faceted benefits.

4. Promote the construction of energy control centers in the steel industry and improve energy management and control levels

Use computer system integration technology, dynamic balance analysis technology, and energy data fusion technology to highlight the company, industry and government At three levels, we build a source energy control center for the steel industry, complete functions such as collection and analysis of energy consumption data of energy-consuming equipment of steel companies, release of energy-saving information and collaborative automated office, and promote the integration of energy conservation and informatization. Establish a basic database for power management in the steel industry, strengthen energy consumption monitoring and analysis, issue early warnings to companies with high energy consumption, strengthen information sharing, and enhance energy-saving work efficiency.
