The presentation discusses the latest developments of the Nippon Sanso DiluJet® Oxy-Air Burner: the burner concept, the benefits of this burner and its application in industrial furnaces.
The DiluJet® Oxy-Air Burner has been further developed with the aim to offer a maximum of flexibility when being implemented at existing furnaces. The burner is able to operate as a traditional Preheated Air-Fuel burner, as an Oxy-Fuel burner or as a hybrid Preheated Air-Oxy-Fuel burner. At the same time the fuel input of the burner can be modified between 100% natural gas, 100% (green) hydrogen or any mix of natural gas and (green) hydrogen. Switching between all these different operation modes, can be done in a straightforward way by the HMI of the PLC system.
The possibility to switch between these different operational modes, creates a very wide flexibility in several areas: furnace throughput, heat transfer mechanism inside the furnace, furnace atmosphere composition, amount of CO2 emissions, specific fuel consumption, furnace OPEX.
Since August 2025, the 4 MW version of this burner has been used non-stop in an European continuous reheat furnace for long steel products during the execution of the EU funded HyInHeat project. The different operation modes have been demonstrated during full-scale operation. Prior to August 2025, this burner has been implemented in several soaking pit furnaces.
