Claims

[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 wooden part of the boiler 1, and a boiler installed inside the water level control box 2. 1, a lower limit water level detector 4 installed in the water level control box 2 to detect the water level of the boiler below the upper limit water level detector 3, and an upper limit water level detector 3. After receiving a water level detection signal from the system, outputs a water pump stop signal, and after receiving a water level detection undetectable signal, outputs a water pump operation signal after a set time h has elapsed during which the water level in the boiler reaches the lower limit of the water level control width due to evaporation. After receiving the undetectable water level signal, if the water level in the boiler does not return to the water level of the upper limit water level detector after the set time t2 has elapsed during which the water level in the boiler reaches the dangerous region of overheating due to evaporation, a combustion equipment stop signal is sent. and a controller 5 which also outputs a combustion device stop signal in response to a water level detection undetectable signal from a lower limit water level detector.
