装置。 A vaporizer is equipped with a heater and a temperature sensor, and heats and vaporizes fuel. During combustion, power is supplied to the heater by phase control, and the vaporizer temperature detected by the temperature sensor is set to a predetermined target temperature. a flame detection means for detecting the presence or absence of a flame by inputting a voltage from a flame rod sensor; forced extinguishing means to be executed; while the flame detection means detects a flame, the operation of the temperature maintenance means is continued; and, conversely, while the flame detection means does not detect a flame, the operation of the temperature maintenance means is continued. An abnormal temperature rise prevention device for a vaporizer in an oil water heater, comprising an operation control means for stopping the vaporizer.
