Industrial demonstration of hot gas injection at the blast furnace (Ideogas)
Publication metadata
The Ideogas project started in March 2006 with the aim of simulating and investigating the recycling of decarbonated top gas (DTG) in the shaft of the blast furnace. Unfortunately, the burner technology foreseen to produce reducing a gas simulating DTG from natural gas did not work and had to be given up. As no effective alternative to produce reducing gas could be found, the Ideogas project was focused on the development of the oxygen tuyere technology for the most difficult configuration of the ULCOS-BF process (Version 1). The on-paper design of these trials was validated by the ULCOS steering committee in May 2008 and the decision was made to go to the second stage of the project, a technological test of the O2-tuyere technology at industrial scale during 15 days. However, the preparation of this test was severely slowed down by the economic crisis and further disturbed by successive stoppages of the pilot BF1 of ArcelorMittalEisenhüttenstadt linked to the market situation. The technological test finally took place in June 2011. The O2-tuyere jointly developed by ArcelorMittal and BFI passed this test successfully. From a process point of view, the tuyere has been operated during about 11 days at an adiabatic flame temperature over 2 300 °C without problem, while the PCI rate was kept above 160 kg/thm, with peaks at 180 kg/thm. The project thus reached the goal of developing a tuyere technology suitable for Version 1 of the ULCOS-BF process.
