Title Received the "Award of Excellence" in the Technology Development Category of the Cogeneration Grand Prix 2022 for the commercialization of a waste heat boiler with a 30% hydrogen co-firing burner.

Chugai Furnace Manufacturing, together with Kawaju Reinetsu Kogyo, Kawasaki Heavy Industries, Ltd. and Daigas Energy Corporation, has received the Cogeneration Grand Prize from the Center for Cogeneration and Energy Utilization (Cogeneration Foundation) for the commercialization of a waste heat boiler with a 30% hydrogen co-firing burner. 2022^*We received the "Excellence Award" in the technology development category.

Exhaust heat boilers generate steam by utilizing the heat of exhaust gas generated from gas turbines. Exhaust heat boilers with an additional burner are installed in plants with particularly high heat demand, such as chemical and paper mills, where the exhaust gas is reheated by an additional burner to increase the amount of steam generated. The award-winning hydrogen 30% co-firing type was developed on the basis of the proven city gas dedicated co-firing burner, and is capable of stable operation by co-firing hydrogen with city gas at a ratio of up to 30% by volume. This product can be installed not only by new installation but also by replacing some parts of existing city gas-fired burners, so that hydrogen energy can be utilized by simply adding a hydrogen supply unit and changing the combustion control program while diverting existing facilities.

When this product is combined with the 8MW-class hydrogen 30% co-fired gas turbine cogeneration system (PUC80D-H2) of Kawaju Reinetsu Kogyo and Kawasaki Heavy Industries, Ltd. to supply electricity and steam, the annual CO emissions compared to a system using a commercial power source and a city gas-fired boiler. In addition, by converting both the city gas-fired waste heat boiler with an additional burner and the gas turbine cogeneration system currently in operation to hydrogen 30% co-firing, it is possible to reduce CO₂ emissions by 6,000 tons per year.
