As special equipment, boilers generally operate under pressure. In order to ensure the safety of the boiler, and to detect minor faults in a timely manner, eliminate and deal with them, gas boilers often install protective devices for early warning.

Safety protection device for gas steam boiler

　　1. Water level monitoring. Current gas-fired steam boilers are equipped with real-time monitoring of boiler water level.

　　2. Time setting. The gas-fired steam boiler adopts PLC control operation, and the start and stop time of the boiler can be freely combined according to needs.

　　3. Leakage protection, the boiler control system will automatically cut off the power after detecting the leakage of the electric heating element.

　　4. Water shortage protection. If the boiler is short of water, the protection device will cut off the burner control circuit in time to prevent the burner from being damaged by dry burning.

　　5. Power supply abnormality protection. If the power supply is abnormal, the gas boiler will automatically stop running.

　　6. Overpressure protection. If the pressure in the boiler exceeds the user's set value, the boiler will automatically start the overpressure interlock protection, prohibit the burner from working and give an alarm.

　　7. In addition, there are other protection devices such as water level alarms, safety valves, extremely low water level alarms and other multiple safety protections, so as to block boiler hidden dangers in time and improve boiler safety.
