Energy conservation and emission reduction is one of the most concerned topics. During the “Twelfth Five-Year Plan†period, energy-saving tasks are heavy and stressful, and industrial energy conservation is still the focus of energy conservation. The steel industry is a high-energy, high-pollution industry and one of the industries with the greatest potential for energy conservation and emission reduction. This article discusses the energy saving measures of the steel industry from the following aspects for your reference. I. Optimize the industrial structure of the steel industry. 2. Promote mature energy-saving and emission-reduction technologies and develop new energy-saving technologies. The steel industry has the characteristics of high energy consumption, many processes, and long process. The input and output of materials in each process segment have a large amount of energy loss. , energy recovery space is large. Accelerate technological transformation, promote the application of dry quenching, coking coal conditioning and air conditioning integration, high-oxygen high-spray coal high-efficiency combustion, blast furnace gas differential pressure power generation, converter dry dust removal and negative energy steelmaking and other energy-saving technologies. Among them, the dry quenching technology is widely used. The cold inert gas is blown into the dry quenching furnace by the circulating fan to exchange heat with the hot red coke, and the coke is cooled. The heated inert gas transfers heat to the boiler to generate steam. The inert gas is blown into the dry quenching furnace through the fan to recycle the steam generated by the quenching boiler or into the steam pipe network of the plant or sent to generate electricity. While promoting existing advanced technologies, we must encourage enterprises to continue to increase research and development efforts, research new technologies and increase the full utilization of waste heat resources. 3. Extending the comprehensive utilization of steel resources The industrial chain extends the comprehensive utilization of the steel resources industry chain, promotes the cooperation between the steel industry and other industries, promotes comprehensive utilization, and encourages the recovery of surplus gas, waste heat, solid waste, wastewater, and comprehensive utilization. The integration of building materials, petrochemicals, electric power and other industries will help improve the overall resource utilization efficiency of the society, reduce the emissions of various pollutants, and achieve win-win results in many aspects. For example, in combination with the building materials industry, make full use of metallurgical slag. The tail slag iron grade is less than 2%. After the process, it is made into slag powder, steel slag powder and steel slag composite powder. It is used for concrete admixture and can replace 10% to 40% of cement clinker to prepare concrete. Fourth, promote the construction of energy control centers in the steel industry, improve energy management and control level. Use energy data fusion technology, dynamic balance analysis technology, computer system integration technology, highlight the three levels of enterprises, industries and governments, build energy control centers in the steel industry, and realize steel enterprises. The main energy-consuming equipment energy consumption data collection and analysis, energy-saving information release and collaborative automation office and other functions, to promote the effective integration of energy conservation and information. Establish a basic database of energy management for key steel enterprises, strengthen energy consumption monitoring and analysis, provide early warning to enterprises with higher energy consumption, strengthen information sharing, and improve energy efficiency. In short, the steel industry is an energy-intensive and indispensable industry. Energy conservation and emission reduction have a long way to go. It is necessary to support the joint restructuring of iron and steel enterprises, promote enterprises to adopt new technologies for research and development, energy conservation and emission reduction, and extend the comprehensive utilization of steel resources. Chain, strengthen the information management level of iron and steel enterprises, and enable enterprises to enter the path of scientific development.
