Shoei Manufacturing Co., Ltd. (President: Masataka Haba, hereinafter referred to as "Shoei Manufacturing") has successfully achieved stable combustion in ammonia-only combustion of a heat recovery burner with an integrated heat exchanger (the first of its kind in Japan) in collaboration with Daigas Energy Co., Ltd. (President: Hiroyoshi Fukutani, hereinafter referred to as "Daigas Energy"), a wholly-owned subsidiary of Osaka Gas Co., Ltd. (President: Masataka Fujiwara). The mixing ratio with city gas has also been realized in the range of 0 to 100%, contributing to the decarbonization and low-carbonization in high-temperature fields such as aluminum manufacturing. At Shoei Manufacturing, we are working on the commercialization of next-generation fuel burners, such as hydrogen burners and ammonia burners, by applying the combustion technology and heat utilization technology we have cultivated so far. We will continue to refine decarbonization and low-carbonization technologies across various temperature ranges and contribute to the development of the manufacturing industry. (Note 1) Based on research by Daigas Energy as of February 2025 (Note 2) A burner equipped with a heat exchanger that achieves high-efficiency combustion by exchanging heat between combustion exhaust gas and combustion air (Note 3) The heat ratio of ammonia within the total heat of city gas and ammonia (mixing ratio of 0% = 100% city gas). Successful stable combustion has been achieved in both city gas-only and ammonia-only combustion.

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.

Together with Tokyo Gas and Tokyo Gas Engineering Solutions, we have developed Japan's first hydrogen combustion recuperative burner (a burner with a built-in waste heat recovery device). (Sales are scheduled for October 2023.) By utilizing waste heat, we reduce fuel consumption and achieve zero carbon dioxide (CO2) emissions during combustion. This contributes to the decarbonization of industrial sectors that require high-temperature heat, such as melting holding furnaces and heat treatment furnaces in aluminum manufacturing, as well as torrefaction heating.

The Thermotech '2022 event held at Tokyo Big Sight has successfully concluded. We would like to express our heartfelt gratitude to the many customers who visited our booth. The most popular item was indeed the "hydrogen combustion burner." We received various questions and words of encouragement after watching the comparison video of hydrogen and natural gas combustion flames. We will continue to develop and refine the hydrogen burner to meet our customers' needs. Additionally, we received many requests for detailed information on other products, including environmental equipment (odor removal systems for on-site demonstrations), painting equipment (hybrid gas and electric), and aluminum alloy oxidation suppression furnaces, as well as surface combustion burners and package mixers. Thank you very much.
