[Exhibition Participation] AXIA EXPO 2025 Hydrogen and Ammonia Next-Generation Energy Exhibition

Successful stable combustion of ammonia combustion. Introducing a heat recovery burner with built-in heat exchanger! Contributing to decarbonization and low carbonization in high-temperature fields.

The "ammonia combustion burner," considered one means of decarbonization, has successfully achieved stable combustion in ammonia-only operation with Daigas Energy Co., Ltd., a 100% subsidiary of Osaka Gas Co., Ltd., using a heat exchanger-integrated waste heat recovery burner. It has also achieved a mixing ratio with city gas ranging from 0% to 100%, contributing to the decarbonization and low carbonization of high-temperature fields such as aluminum production. This burner can be used in industrial furnaces and thermal equipment that require high-temperature heat, including aluminum manufacturing processes (melting, holding, preheating) and heat treatment, as well as in the automotive and automotive parts manufacturing sectors. 【Features】 - Zero CO2 emissions during ammonia-only combustion - Achieves stable combustion in ammonia-only operation - Stable combustion with city gas mixing in the range of 0% to 100% - High efficiency, space-saving, and low-cost with a heat exchanger-integrated waste heat recovery design By developing a dedicated nozzle optimized for mixing fuel gas and air for ammonia co-combustion, stable combustion has been achieved across a wide ammonia mixing ratio of 0% to 100% at a combustion volume of 50 kW. Moving forward, we will work on resolving remaining issues such as NOx reduction and aim for early practical application.

A hydrogen burner equipped with a waste heat recovery device has arrived! Not only does it contribute to decarbonization through hydrogen combustion, but it can also reduce fuel usage by approximately 30% due to its built-in heat exchanger.

"Hydrogen combustion," considered a means of decarbonization, developed in collaboration with Tokyo Gas Co., Ltd. and Tokyo Gas Engineering Solutions Co., Ltd.! A hydrogen gas burner based on the highly proven recuperative burner "STBW." Used in manufacturing processes/industrial furnaces that require high-temperature heat, such as aluminum alloy production (melting, holding, and preheating). 【Features】 □ Zero CO2 emissions during combustion due to dedicated hydrogen combustion □ Built-in waste heat recovery system reduces fuel usage by approximately 30%* □ No need for external heat exchangers as waste heat recovery is possible within the burner itself □ Low-cost and compact with a highly efficient combustion system □ Achieves both low NOx and stable combustion □ Hydrogen combustion can be achieved simply by replacing existing burner components □ Capable of dedicated city gas/natural gas combustion, allowing for adaptation to gas supply conditions (*Based on data from actual furnaces using natural gas) The STBW burner you are using can be converted to hydrogen combustion by replacing parts, allowing for evaluation tests on the impact of hydrogen on workpieces and verification of decarbonization. *Hydraulic equipment compatible with hydrogen combustion is required. Please contact us for more details and consultation.

At Seiei Manufacturing, we are proposing low-carbon painting drying ovens to respond to a decarbonized society.

At Shoei Manufacturing, which has extensive experience with painting drying ovens and exhaust gas treatment systems, we offer a lineup of "hydrogen combustion type" and "electric heater type." By using "renewable energy sources" and "hydrogen fuel," we can achieve decarbonization. Even if these options are not currently available, we can adapt to the uncertain future of energy supply by introducing: - A hybrid type that electrifies part of the heat source configuration - Hydrogen gas burners that can also use city gas/propane gas. 【Painting Baking Drying Oven】 Hot Air Zone (100–250°C) ⚪︎ Hydrogen combustion hot air generator "AH-H2" ⚪︎ Electric hot air generator "AH-E" Radiant Baking Heating Zone (700–850°C) ⚪︎ Electric infrared heater ⚪︎ Hydrogen combustion burner Water Removal Drying Oven (100–150°C) / Booth Heating ⚪︎ Hydrogen combustion hot air generator "AH-H2" ⚪︎ Electric hot air generator "AH-E" 【Exhaust Gas Treatment System / VOC Treatment】 ⚪︎ Electric catalytic deodorization device (CT) ⚪︎ Electric regenerative thermal oxidizer (RTO) Our Thermal Technology Research Institute is equipped with a painting drying test oven (QCO) with a painting booth.

A test furnace based on actual equipment that uses a hydrogen burner for melting and an electric heater for holding. It is possible to conduct thorough tests for decarbonization in aluminum casting sites together with our customers!

It is possible to conduct aluminum melting tests using hydrogen combustion with ingot input. Please use it to verify the quality of the molten metal and its impact on the products. The melting gas burner employs a hydrogen burner and electric heaters for retention! It is a hybrid furnace that enables carbon neutrality. By exchanging burner components, you can switch between fuel gases (hydrogen/LNG (natural gas)/LPG), allowing for adaptability based on gas supply trends. Additionally, the furnace structure has a high oxide suppression effect, which you can verify in actual operation. We are committed to solving problems in aluminum casting sites and promoting low carbonization.
