Since the beginning of this year, TISCO has been accelerating improvement in energy efficiency amid substantial lifting of the company’s production efficiency. In order to pursue the ultimate energy efficiency under extreme production efficiency, the energy system of the company has made overall planning and effectively coordinated with related units. At present, the energy efficiency index of TISCO has steadily entered the forefront of China Baowu.
Benchmarking. In order to promote the energy efficiency benchmarking, TISCO Energy System formulated a dedicated plan, taking accurate benchmarking as the starting point, carrying out project-like promotion on key upgrading indicators, keeping a close eye on the key process energy consumption indicators and measures, and systematically promoting energy efficiency upgrading. All specialties and processes have been actively optimized accordingly. After the implementation of the plan, the energy efficiency indicators of all processes in TISCO have made remarkable progress, with over one-third of the key process energy efficiency indicators ranking the top three in China Baowu, and the main energy efficiency indicators have steadily entered the forefront of the group and leading the industry.
Energy balancing. Facing the energy balance problem caused by the rapid improvement of production efficiency, TISCO's energy system took immediate action. By adapting the advanced technology, they quickly determined a number of new measures which focused on the use of technological upgrading and the transformation of energy utilization methods to solve the energy rebalancing problem. These measures include reforming high-efficiency boilers, changing natural gas for cold rolling acid regeneration into coke oven gas, baking AOD furnace shell into coke oven gas, baking converter gas, and using waste heat steam produced by steelmaking to create vacuum. Some of these measures have been implemented and some are being promoted, and the energy balance will be further optimized after the implementation of these measures.
Breakthrough. TISCO's energy system has organized a number of inter-departmental working teams to carry out joint research on key and difficult problems, some key projects having achieved initial progress. For example, "quality optimization of steam system pipeline network configuration" has been completed in several projects, "optimization of supply and consumption of hot rolling mill gas system" has effectively reduced the ratio of natural gas in two hot rolling lines, and "improvement of water system quality index" has improved the water production rate of membrane system, reduced the discharge of external drainage, and further consolidated the ecological double-cycle outcome of water system. The implementation of these key measures has played an important role in solving the key and difficult problems of the energy system.
Carbon layout. TISCO has thoroughly implemented the General Secretary Xi Jinping's instructions on carbon neutralization and carbon peak. The company, following the re-arrangement and new layout of double carbon action, actively prepares for the dual carbon management system, and coordinates the carbon neutralization action. It set up the Carbon Neutralization Office, deeply studied the policies, pioneered low-carbon work, prepared the peak carbon dioxide emissions action plan, and schemed the measures of carbon reduction. The company will make concerted efforts in the new journey of carbon neutrality in peak carbon dioxide emissions, and make positive contributions to green steel, low-carbon society, beautiful China and harmonious earth home.
