Danieli Centro Combustion (a subsidiary of Danieli Group – an Italian steel equipment supplier) will supply two hydrogen-powered reheating furnaces to German steelmaker ThyssenKrupp Steel Europe AG, Duisburg plant in Germany.
Both furnaces are complete walking-beam furnaces to be used to reheat the steel slabs for making flat steel. The furnaces are part of the ThyssenKrupp Steel Strategy 20-30 and will be ready for operation in 2024.
The furnaces will achieve high productivity with reduced energy consumption and NOx emissions. The combustion system would be able to use hydrogen around 48% in volume and maximised by about 66%. The hydrogen blend will improve furnace efficiency and would reduce CO2 emission by around 53 kg/tonne.
ThyssenKrupp has been working on several hydrogen projects to reduce emission. In February 2021, the company completed the first phase of hydrogen tests on ‘Blast Furnace 9’ in Duisburg, where it conducted several tests on one of the 28 tuyeres of the blast furnace. In the next step, the tests will be extended to all 28 tuyeres of the blast furnace.
