Smart Solutions Hydrogen-Ready Burner for Heat Treatment Furnaces
Tenova has introduced the new TRKSX (Tenova Self-ReKuperative Flameless) Smart Burner for heat treatment furnaces in the metals industry. The smart burner also helps to maintain NOx emissions well below the strictest future limits.
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.
The new 200-kilowatt TRKSX (Tenova Self-ReKuperative Flameless) Smart Burner 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, adds the firm.
The new Smart Burners 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, mentions the company.
The Smart Burner 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.
The firm’s burner portfolio is also integrated with sensors to make possible dynamic control of waste gases flow, generating precious data for machine learning applications.
