Flame Relay

A Flame Relay is a safety device used in heating systems to detect the presence of a flame. It works by sensing a small electrical current produced when a flame is burning, often using a flame sensor or probe. If the flame goes out or is not detected, the relay automatically shuts off the fuel supply, preventing dangerous gas buildup or potential explosions. Essentially, it acts as a safety switch that ensures the heater only operates when a flame is present, maintaining safe operation and preventing hazardous conditions.
