The safety protection devices and their functions of the gas-fired steam boiler

1) Water level monitoring, which can monitor the real-tine water level of the boiler.

2) Time setting, which can set the boiler start and stop time freely via the PLC control system.

3) Electric leakage protection, which can automatically cut off the power once the boiler control system detects the electric leakage of the electric heating element.

4) Water shortage protection, which can cut off the control circuit of the burner timely to prevent the burner from burning out.

5) Power abnormality protection, which can automatically stop the boiler operation.

6) Overpressure protection, which can automatically start the overpressure interlock protection to stop the combustor and give an alarm.

7) Other safety protection devices such as water level alarm apparatus, safety valves, extremely-low water level alarm and so on, which can improve the boiler safety by preventing the hidden dangers timely.
