Tenova Italimpianti is the leading technology and equipment supplier for the world of industrial furnaces, leveraging on the proprietary in-house expertise in the production of best-in-class burner technologies since 1960s, combining the company’s engineering know-how and advanced knowledge of the combustion field.
A Tenova brand, it includes and exploits the heritage of the former company founded in Genoa (Italy) in 1957 for the technologies of reheating, heat treatment, strip processing and acid regeneration plants.
Combustion technologies for heating furnaces (reheating and heat treatment processes) have evolved to reduce fuel consumption while maintaining, or reducing, nitrous oxides (NOx) emissions.
The Tenova TRKSX H2/NG burner is a new flame/flameless self-recuperative burner for treatment furnaces. The burner is equipped with a metallic counter-current heat exchanger that uses the exhaust gases sucked from the furnace to preheat the combustion air. This solution allows to reach a burner efficiency over 75%.
This burner features different combustion techniques to reduce pollutant formation, such as air and fuel staging, as well as flameless combustion.
Tenova participated to a series f projects to build a knowledge base of industrial guidelines for hydrogen use in reheating and Heat Treatment furnaces.
As part of the Tenaris Dalmine Zero Emissions project, Tenova supplied the first heat treatment furnace completely equipped with "Hydrogen Ready" burners (see pictures below). This movable hood furnace is designed to treat special steel bars up to 12 meters long, and is equipped with 34 TRKSX self-recuperative flameless burners that are ready to work with any NG/H2 mixture, and up to 100% H2.
