を備えた三位置制御式ボイラーにおいて、燃焼途
中に失火が発生した場合、低燃焼状態から高燃焼
状態移行時の失火であるか否かを判別し、このと
きの燃焼移行時の失火が繰り返して発生したとき
にボイラーを再起動させないで停止させるように
働く判別器１７を設けたことを特徴とする三位置
制御式ボイラーの燃焼制御装置。 In a three-position control boiler equipped with a combustion control mechanism that has a recycle function in the event of a misfire, if a misfire occurs during combustion, it is determined whether the misfire occurred during a transition from a low combustion state to a high combustion state, and A combustion control device for a three-position control boiler, characterized in that a discriminator 17 is provided which operates to stop the boiler without restarting it when misfires occur repeatedly during combustion transition.
