As autumn deepens, the temperature gradually drops. As an important heating equipment, the frequency of use of boilers also increases. In this critical period of October 2024, it is particularly important to understand and master the correct use and safety knowledge of boilers. The following is a comprehensive guide to boiler use and safety knowledge, which aims to help users better manage and maintain boiler equipment to ensure safe and efficient enjoyment of warmth.
 

1. The basic working principle of boilers

  A boiler is an energy conversion device that uses the heat energy generated by fuel combustion to heat water into steam or hot water, and then transports it to various hot spots through pipelines to achieve heating or process heat. The core components of the boiler include burners, heat exchangers, control systems, etc., which work together to ensure the stable operation of the boiler.
 

2. Correct use of boilers

Pre-start inspection: Before starting the boiler, the boiler body, combustion system, control system, etc. should be fully inspected to ensure that all components are intact, tightly connected, and leak-free. At the same time, check whether safety accessories such as water level gauges, pressure gauges, and safety valves are sensitive and reliable.
Ignition and heating: According to the boiler operating procedures, ignition and heating operations should be carried out step by step. Pay attention to controlling the heating speed to avoid rapid heating that may cause uneven heating of the boiler, excessive stress, and other problems.
Operation monitoring: During the operation of the boiler, close attention should be paid to changes in key parameters such as water level, pressure, and temperature, and the combustion intensity and circulating water volume should be adjusted in time to ensure that the boiler operates under safe and economic conditions.
Blowdown and descaling: Regular blowdown and descaling are important measures to keep the boiler water clean and improve thermal efficiency. A reasonable blowdown and descaling plan should be formulated according to the water quality and strictly implemented.
 

3. Boiler safety knowledge

  The importance of safety accessories: Safety accessories such as water level gauges, pressure gauges, and safety valves are important guarantees for the safe operation of boilers. These accessories should be calibrated regularly to ensure their sensitivity and reliability. Once an abnormality is found, the machine should be shut down immediately for processing.
Prevent overpressure operation: Overpressure operation of the boiler is one of the main causes of accidents. Therefore, the working pressure of the boiler should be strictly controlled and should not exceed the design pressure. At the same time, an overpressure protection device should be set up, and once the pressure exceeds the set value, the machine will automatically shut down and alarm.
Prevent dry burning due to lack of water: Dry burning due to lack of water in the boiler will cause overheating, deformation and even rupture of the boiler heating surface. Therefore, the boiler water level should be checked regularly to ensure that the water level is within the normal range. Once the water level is abnormal, the boiler should be shut down and water should be replenished immediately.
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. It is hoped that users can carefully study and master this knowledge to ensure the safe and efficient operation of the boiler and provide strong guarantees for winter heating work.
