Prevent over-temperature operation: Over-temperature operation of the boiler will accelerate the aging, corrosion and scaling of the heating surface and reduce the service life of the boiler. Therefore, the outlet water temperature of the boiler should be strictly controlled and must not exceed the design temperature. At the same time, an over-temperature protection device should be set up, and once the temperature exceeds the set value, the boiler will automatically shut down and alarm.
Regular maintenance: Regular maintenance of the boiler is the key to ensure its long-term stable operation. A detailed maintenance plan should be formulated, including cleaning the burner, replacing the filter, checking the seals, etc., to ensure that all parts of the boiler are in good working condition.
 

4. Emergency treatment measures

During the operation of the boiler, once a fault or accident occurs, emergency treatment measures should be taken immediately to prevent the situation from escalating. The following are some common emergency treatment measures:

Shutdown alarm: Once the boiler is found to be abnormal or faulty, it should be shut down immediately and the alarm should be sounded, and the relevant personnel should be notified to handle it.
Cut off the fuel supply: When shutting down, the fuel supply should be cut off quickly to prevent the spread of fire or explosion accidents.
Discharge steam or hot water: After shutting down, the discharge valve should be opened to discharge the steam or hot water in the boiler to reduce the pressure and temperature in the boiler.
Evacuate personnel: In an emergency, personnel in the boiler room and its surroundings should be evacuated quickly to ensure personnel safety.
Contact professionals: While taking emergency measures, professional boiler maintenance personnel or relevant institutions should be contacted as soon as possible for further troubleshooting and repair work.
In summary, the Boiler Use and Safety Knowledge Guide in October 2024 covers many aspects such as the basic working principle of the boiler, correct use methods, safety knowledge, and emergency treatment measures.
