Tenova has announced the launch of the development of the first burners for heat treatment furnaces using up to 100% hydrogen while keeping NOx emissions largely below the strictest limits, aligning with Tenovas initiatives to a decarbonized industry production.
The company continues its efforts towards carbon neutrality with a unique portfolio of hydrogen-ready technologies. The launch of the self-recuperative burner for heat treatment furnaces follows the recent release of the multi-megawatt TSX SmartBurner family for reheating furnaces, fueled with a mixture of natural gas and hydrogen (up to 100%).
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 to keep nitrogen dioxide emissions well below the strictest future limits.
Davide Astesiano, R&D Manager at Tenova Italimpianti, commented,
“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 at 3% of oxygen even with 100% hydrogen.”

The TRKSX SmartBurner has been designed in consideration of the decarbonization goals of the steel industry. It claims that it will be first installed in a heat treatment furnace for pipes at the productive site of Tenaris (in Dalmine, Italy).
Nicola Cavero, Senior Vice President at Tenova Italimpianti said,
“Our target is to enlarge Tenova’s burner portfolio to offer our customers the best solution for the decarbonization of their plants, and we plan to adapt all our burners to be hydrogen-ready. They are also integrated with sensors to make possible dynamic control of waste gases flow, generating precious data for machine learning applications.”
