Energy-saving exhaust heat recovery type recuperative burner [STBW burner]
Utilize waste heat at low cost! Energy-saving effects with a high-efficiency burner using preheated air! Introducing a gas burner with built-in heat exchanger for waste heat recovery.
The STBW burner is a heat recovery type burner equipped with a heat exchanger that collects combustion exhaust gases from around the gas burner combustion tube. Compared to regenerative burners and external heat exchangers, the STBW burner maintains a low initial cost while contributing to a quick return on investment with a fuel-saving efficiency of approximately 30%. By incorporating a simple heat-resistant heat exchanger, it features a low-cost structure that is less prone to clogging. The flame detection mechanism is integrated with the burner, allowing for a direct ignition method that does not require a pilot burner, resulting in excellent maintenance characteristics. 【Features】 - The price of the burner is significantly lower, offering excellent cost-effectiveness. - Self-exhaust gas recovery (recovery from the burner tip) - No need for a heat exchanger or waste heat recovery duct on the furnace side - Built-in heat exchanger made of heat-resistant metal - Excellent maintenance characteristics - Capable of high-load combustion in a sealed state *For more details, please refer to the PDF document or feel free to contact us.

Successfully achieved stable combustion of ammonia dedicated burners. The first in the country as a burner with an integrated heat exchanger!
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.

Developed a high-efficiency, low-NOx waste heat recovery hydrogen burner.
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.

Thank you for visiting Thermotech 2022!! June 1 (Wednesday) to June 3 (Friday), 2022 at Tokyo Big Sight.
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.
