Taiyo Nippon Sanso has developed a converted gas generation process for heat treatment furnaces utilizing oxy‑fuel combustion* technology.
Conventional technology employed hydrocarbon gases—such as LPG or city gas—as well as air and a nickel catalyst, requiring substantial electric power consumption for heating. By leveraging its long‑cultivated oxy‑fuel combustion technology, the Company developed a process that supplies the heat required for the catalytic reaction through combustion of combustible gas with oxygen, enabling significant energy savings and achieving an 80 % reduction in CO₂ emissions. The company is advancing practical evaluations of this process technology for heat treatment furnace users, particularly in carburizing, annealing, and sintering applications, with the aim of commercialization at an early stage.

* Oxy‑fuel combustion refers to combustion using oxygen or oxygen‑enriched gas as the oxidizer.
