  On February 12th, the National Development and Reform Commission published the National Key Energy-Saving Low-Carbon Technology Promotion Catalogue (2017 Version, Energy Saving Section). CISDI’s declared ‘Smart large-scale blast furnace energy saving technologies based on bosh gas index optimization’ was successfully selected for inclusion, becoming the only selected project in the steel and iron industry in 2017.

  The energy consumption of blast furnace production accounts for about 60% of the total consumption of the steel and iron industry. With green transformation and the development of the steel and iron industry, intelligent green blast furnaces will become the inevitable trend and choice in the future, and blast furnace energy-saving technology has great development potential. ‘Smart large-scale blast furnace energy saving technologies based on bosh gas index optimization’ includes five key technologies: high efficiency and low consumption theory system based on bosh gas content index, reasonable furnace profile design technology combining bosh gas index theory and blast furnace simulation, reasonable furnace profile construction technology of large blast furnaces, energy saving technology of large blast furnace systems and intelligent production management systems of large blast furnace. These technologies can help large blast furnaces to realize high efficiency and low consumption indexes, including fuel ratio of ≤ 485 kg/ton and coal gas use ratio of ≥ 52%, thereby reaching the international advanced level. It is estimated that in the next five years, the technology will be popularized by 23% with a total investment of RMB 34 billion, resulting in an annual energy saving potential of 3.24 million tons of standard coal and an annual carbon emission reduction capacity of 8.55 million tons of carbon dioxide.

  Organized and prepared by the National Development and Reform Commission, the National Key Energy-Saving Low-Carbon Technology Promotion Catalogue aims to guide energy using units to adopt advanced and applicable new energy saving technologies, devices and processes, encourage energy resource saving and integrated utilization, and promote green development. It was first issued in 2009 and 19 new energy-saving technologies were added in 2017. By December 2017, 260 projects had been completed in 13 industries such as coal, electricity, iron and steel, nonferrous metals, petrochemicals, chemicals and building materials. It includes 32 projects involving the iron and steel industry. The selected projects can play positive and advantageous roles in improving brand competitiveness and bidding technology evaluation.
