Hydrogen-Ready Burner for Industrial Heat Treatment

Tenova, a leading company in sustainable solutions for the green transition of the metals industry, announced the accomplishment of a key milestone towards a more sustainable combustion process: the development of the first burners for heat treatment furnaces using up to 100% hydrogen while keeping NOx emissions largely below the strictest limits.

Tenova continues its efforts towards carbon neutrality with an important achievement resulting in a unique portfolio of hydrogen-ready technologies. After the recent launch of the multi-megawatt TSX SmartBurner family for reheating furnaces fueled with a mixture of natural gas and hydrogen (up to 100%), the company is now ready to bring onto the market a self-recuperative burner for heat treatment furnaces.

The new 200-kilowatt TRKSX (Tenova Self-ReKuperative Flameless) SmartBurner was successfully tested with a variable fuel mixture of natural gas and hydrogen to potentially eliminate CO2 emissions during the combustion process. The system works in flame and flameless mode with the aim to keep nitrogen dioxide emissions well below the strictest future limits.

“TRKSX SmartBurners preheat the combustion air at high temperature directly into the burner body through the heat-exchanger. This makes it possible to reduce fuel consumption significantly, making this technology extremely efficient (approximately 78%). Moreover, it allows to maintain minimum level of NOx emissions, releasing less than 80 mg/Nm3 @ 3% of oxygen even with 100% hydrogen.”, affirmed Davide Astesiano, R&D Manager at Tenova Italimpianti.

The TRKSX SmartBurner was designed in consideration of the decarbonization goals of the steel industry, and will be first installed in a heat treatment furnace for pipes at the productive site of Tenaris (in Dalmine, Italy), a leading global manufacturer and supplier of steel pipe products and related services for the world’s energy industry and other industrial applications and part of the Techint Group, to which Tenova also belongs.
