Introduction to the test of a hydrogen combustion aluminum melting holding furnace for decarbonization.

The "Hydrogen and Ammonia," the ultimate energy that does not emit carbon dioxide. The AXIA EXPO 2025 - Hydrogen and Ammonia Next-Generation Energy Exhibition, which is attracting global attention for the realization of a carbon-free society, will be held. Seihei Seisakusho, a gas burner and industrial furnace manufacturer, will showcase hydrogen and ammonia-related products in a panel display at the booth of the Kinki Bureau of Economy, Trade and Industry (C-02). We will deliver a wealth of content, including the latest information on hydrogen and ammonia burners and an introduction to decarbonized thermal equipment.

Seihei Seisakusho, a manufacturer of gas burners and industrial furnaces, will participate in the Thermal Technology 2024 event, which consists of an exhibition of industrial furnaces and related equipment, as well as seminars and lectures, serving as an information dissemination event from the Kansai region. We will propose decarbonization and low-carbon items for production equipment, including: - "Low-carbon painting and drying equipment" - "Hydrogen × electric hybrid aluminum melting and holding furnace" - "Hydrogen gas burners" Additionally, we will have a wide range of energy-saving burners and furnaces equipped with them on display, and we look forward to your visit.

At Seiying Manufacturing, we are working on the development of aluminum industrial furnaces that can contribute to achieving carbon neutrality and a decarbonized society. Recently, we conducted aluminum melting tests using hydrogen gas burners in collaboration with customers aiming for carbon-neutral manufacturing. For the test furnace, we adopted the "SMH type" melting holding furnace, which generates extremely low amounts of oxides. The heat source consisted of a hydrogen-exclusive gas burner "EIS-H2" for melting and an electric heater for holding the molten aluminum, creating a hybrid configuration. In this melting test, we compared the "melting speed" and "aluminum molten quality" with those of an LPG combustion gas burner that was conducted beforehand. We will continue to analyze the detailed test results. For more details about this test furnace, please refer to the attached materials. Feel free to contact us regarding the implementation of the tests.

"Carbon Neutral Aluminum Melting Holding Furnace Developed by Shoei Manufacturing Co., Ltd." Published in "Steel News, October 23, 2023, Page 5." Shoei Manufacturing Co., Ltd. (Headquarters: Hirano Ward, Osaka City, Representative: Shota Habaki), a specialized manufacturer of industrial gas burners and industrial furnaces, has developed an aluminum melting holding furnace that enables decarbonization in aluminum casting sites, such as those for automotive parts. A new hydrogen gas burner that emits no CO2 during combustion has been adopted for the melting line. By placing high-efficiency immersion heaters in the holding line for the molten aluminum melted by hydrogen combustion, a thermal source configuration that enables carbon neutrality through "hydrogen × green electricity" has been achieved. A test furnace based on actual equipment has been newly established at the Thermal Technology Research Institute. We are accepting visits to observe hydrogen combustion and tests for actual aluminum melting. Amid uncertainties regarding future energy supply, we will contribute to the decarbonization of the manufacturing industry by applying the combustion technology and hybridization technology for thermal sources that we have cultivated so far.
