OXYGON 400 datasheet.pdf
Our OXYGON® technology moves beyond conventional burner designs to harness highly efficient flameless oxyfuel combustion for significant energy savings.
Our OXYGON® preheating system is available in two versions for different vessel sizes and different levels of flexibility. Safety is a top priority at Linde, so we make sure that all of our products and solutions comply with the relevant safety standards.
Who is it for?
OXYGON® 400 is an oxyfuel system with a nominal power of 400 kW. It is ideal for customers looking for a simple, efficient method of preheating typical foundry vessels with capacities from 1 to 20 tons.
How does it work?
An OXYGON® 400 plug & play system is mounted on the vessel lid. Thee accompanying control system automatically controls the ladle temperature by using ON/OFF control of the semi-flameless combustion process. When the full power is off during a heating operation, the pilot burner is burning, ensuring the operational safety.

Who is it for?
OXYGON® XL is based on the same technology as OXYGON® 400, but comes with a more advanced control system as well as a 1.5 MW burner suitable for vessels with capacities from 30 to 150 tons.
How does it work?
An OXYGON® XL plug & play system is mounted on the vessel lid and the accompanying control system automatically controls the combustion processes, seamlessly switching between semi-flameless and completely flameless combustion modes when the temperature rises well above the self-ignition point of the fuels (in accordance with legislation).

We can tailor our systems to individual customer needs – supporting, for example, higher-power designs or the use of alternative fuels.
Customer: Scana Steel AB is based in Björneborg, Sweden. The company is a steel producer and solution provider, serving global industries such as power, oil and gas, shipping and manufacturing. Scana is one of the few players in the field with integrated production facilities that include steel melting, heat treatment, forging and steel component machining. It specialises in shafts, rotors, risers and joints, as well as forged steel for tool manufacturers.
Challenge: At its facilities, Scana Steel uses an electric arc furnace (EAF) to melt scrap. To follow the melt cycle, one ladle must be operational at all times. For the ladle to be functional, it needs to be dried and preheated to avoid refractory wear and temperature losses. Scana used air/fuel burners to do this. However, these burners were inefficient, requiring around 50 hours to reach the target temperature of 1000°C. In addition to poor thermal efficiency, the air/fuel burners were highly unreliable and often resulted in unplanned downtime. These old burners required continuous maintenance and gave rise to multiple safety issues. Scana was keen to overcome these drawbacks.
“The OXYGON® XL flameless oxyfuel solution from Linde makes our work much easier and safer. But it also gives us much greater process control, allowing us to speed up heating times by more than 50%, while cutting costs and improving our environmental performance.”
Peter Harnesk, Production Manager of Scana Steel AB
