Claims (1)
、給水ポンプの作動・停止信号を出力するように
した構成において、バーナの燃焼時間からボイラ
内の水位を演算し、該演算水位が所定値に低下し
たにも関わらず、前記水位検出棒から給水ポンプ
作動信号がなければ、警報信号を出力し、かつバ
ーナへの燃料供給管に介装した燃料制御弁に閉弁
信号を出力する比較器を設けてなることを特徴と
するボイラの空焚き防止装置。 In a configuration in which the water level detection rod built into the water level detector outputs a water pump start/stop signal, the water level in the boiler is calculated from the burner combustion time, and the calculated water level drops to a predetermined value. A comparator is provided which outputs an alarm signal and outputs a valve closing signal to a fuel control valve interposed in the fuel supply pipe to the burner if there is no water pump activation signal from the water level detection rod despite the above water level detection rod. A boiler dry-firing prevention device that is characterized by:
