In 2018, Chugai Ro Co., Ltd., with Toyota Motor Corporation, succeeded in developing the world’s first general-purpose industrial hydrogen burner. By changing the structure of the hydrogen combustion burner from the conventional burner, it became possible to slowly mix hydrogen and combustion air and suppress a local flame temperature rise. In addition, the amount of NOx produced can be reduced to the less level than the conventional 13A combustion. Furthermore, in order to reduce the environmental load of the industrial furnace, we also developed a radiant tube and a superheated steam generator for this general-purpose hydrogen burner. By the development of the hydrogen combustion type radiant tube burner, it was confirmed that the temperature distribution performance and safety are the same as those of the conventional product, and the fuel conversion compatibility from the conventional product is possible. It was discovered that the superheated steam generator has the property of being able to change the atmosphere inside the furnace to an oxidizing/reducing atmosphere by changing the combustion ratio of hydrogen and Oxygen. We believe that the development of these devices has made great strides toward the construction of a carbon-free society.
