。[Scope of Claim for Utility Model Registration] A water level control box 2 whose upper part communicates with the steam part of the boiler 1 and whose lower part communicates with the water part of the boiler. After receiving a water level detection failure signal from the water level detector 3 and the water level detector 3, a water supply pump operation signal is output when a set time t2 such that the water level of the boiler reaches the lower limit of the water level control width has elapsed. At the same time, a controller 4 is provided which outputs a combustion stop signal if the water level in the boiler does not return to the water level detected by the water level detector by the time the set time t 3 has elapsed during which the boiler is in the danger zone of overheating. In the boiler water supply control device, if the conduction state of the water level detector after receiving the water level detection undetectable signal is less than the set time Δt for preventing malfunction, a determination is made to continue counting the set times t2 and t3 . An abnormal water level drop prevention device for a boiler, characterized in that a device 5 is added to a controller 4.
