Taiyo Nippon Sanso Corporation (Head office: Shinagawa-ku, Tokyo; President: Kenji Nagata; hereinafter "TNSC"), a Japanese industrial gas business company in the Nippon Sanso Holdings Group, and Nippon Gases Euro-Holding S.L.U. (Head office: Madrid, Spain; President: RaulGiudici; hereinafter "NGE") have successfully completed the first demonstration test of the “Innova-JetHydrogen” hydrogen-oxygen combustion burner for steel reheat furnaces at a customer's productionfacility in Europe (ArcelorMittal Olaberria).In order to reduce CO
2 emissions from the many industrial furnaces in Japan and contribute to the realization of a carbon-neutral (CN) society, we are promoting technological development aimed at applying oxyfuel combustion technology to various industrial furnace processes.

1. Overview
TNSC and NGE conducted a demonstration test using the “Innova-Jet Hydrogen (Figure 2)” at a walking beam steel reheating furnace (Figure 1) owned by steel manufacturer ArcelorMittal at Olaberria site. Together with our partner Sarralle, two air burners were replaced by the Innova-Jet Hydrogen, using 100% green hydrogen generated by water. The CO
2 emission reduction efficiency, furnace temperature distribution, and NOx suppression were verified.
The reheating furnaces in steel plants are most energy-intensive, consuming up to 80% of a factory’s fuel. The oxy-fuel technology represents an important step toward the decarbonization. The steel industry now releases around 9% of global CO₂ emissions.

2. Key Characteristic of Hydrogen-oxygen Combustion Burner
The Innova-Jet Hydrogen was designed for use in steel reheating furnaces. The Innova-Jet Hydrogen has a wide turn down ratio and can be used with everything from preheated air combustion to oxygen combustion, and from LNG combustion to hydrogen combustion. Figure 4 shows an example of the fire flame of Innova-Jet Hydrogen. The Innova-Jet Hydrogen is a burner that provides uniform temperature heat distribution and low NOx emissions.
