Taiyo Nippon Sanso Corporation (TNSC) successfully conducted the world’s first trial demonstration of using fuel ammonia for combustion in a glass melting furnace under the development of ammonia combustion technology for industrial furnaces project commissioned by the New Energy and Industrial Technology Development Organization (NEDO). The trial demonstration of ammonia combustion technology was carried out using an ammonia-oxygen combustion* burner installed in the architectural glass production facility at AGC Inc.’s Yokohama Technical Center. The demonstration obtained the result that NOx concentration in the exhaust gas was below the environmental standard even while maintaining the glass furnace temperature. Going forward, testing will be conducted with scaled-up burners and through trial demonstrations in glass melting furnaces at other sites to determine the scope that ammonia fuel combustion technology can be used. We aim to see full-fledged introduction in glass melting furnaces from FYE2027 onward.
