What is a flame safeguard system?
16 Apr 2021
Safeguard system is a set of controls used on a boiler to ensure safe burner operation. Primary functions include:
A safe way of starting and shutting down the burner. This can be accomplished either automatically or manually.
A flame safeguard system also starts the burner in the proper sequence. For example it will purge the combustion chamber of gas, light the pilot and then open the main gas valve.
The flame safeguard system will also continually monitor burner operation when the boiler is on-line.
The system will protect the boiler from excessive pressure or temperature conditions.
It will also regulate the firing rate according to the demand for heat or steam.
Finally, it will standby during down time, waiting for the signal to start the burner once again.
