The present invention relates to a heat and hydrogen generating device. The actual O 2 /C molar ratio is brought close to the target O 2 /C molar ratio at the start of normal operation. The heat and hydrogen generator includes a burner combustion chamber (3), a burner (7) for supplying fuel and air to the burner combustion chamber (3), and a reforming catalyst (4). The target value of the O 2 /C molar ratio of the air and fuel that react in the combustor combustion chamber (3) is set in advance as the target O 2 /C molar ratio. The actual O 2 /C molar ratio during the warm-up operation is estimated from the temperature rise rate, the amount of temperature rise, or the time required for the temperature rise of the reforming catalyst ( 4 ) during the warm-up operation, and the estimated When the actual O 2 /C molar ratio deviates from the target O 2 /C molar ratio during the warm-up operation, the estimated actual O 2 /C molar ratio is approached to the target O 2 /C during the warm-up operation. The direction of the 2 /C molar ratio corrects the supply ratio of the supply amount of the burner combustion air and the supply amount of the burner combustion fuel. |
