SUMMARY:Hydrogen-enriched carbonic oxide recycling oxygenate furnace
DESCRIPTION:According to the International Energy Agency, global energy-related CO2 emissions in 2019 were about 33 billion tonnes, of which nearly 14% were generated by the iron and steel industry, while the energy consumption and emissions of the iron and steelmaking system accounted for about 70% of the total energy consumption and emissions of the whole iron and steel process, and the development of low-carbon iron and steelmaking technology is an effective way for the iron and steel industry to achieve low-carbon development and green and sustainable development.

Sinosteel actively practices the low-carbon and green development strategy. In July 2022, the hydrogen-rich carbon cycle oxygen blast furnace pilot project was successfully put into production, and in the subsequent experiments, key technologies such as 1200°C gas heating technology, gas CO2 removal technology, hydrogen-rich gas/decarbon gas heating and blowing were realized one after another, and the 1200°C high temperature gas self-circulation blowing and hydrogen-rich smelting were carried out under oxyfuel smelting working conditions The industrialization test of the hydrogen-rich carbon cycle oxygen blast furnace (HyCROF) process has been completed. A milestone of 30% reduction in solid fuel consumption and 21% carbon reduction has been achieved (as of November 2022). The new process is safe, stable, smooth and efficient, with strong resistance to fluctuations, low manufacturing costs and good compatibility with traditional manufacturing processes.

This paper will introduce the new HyROF process and its engineering practice milestones with a view to providing a reference for the industry.
