How does a flame failure device work?
Your Flame Failure Device is a key safety feature for your cooker. It is responsible for stopping the flow of gas to the burner of your gas cooker if the flame has been extinguished for any reason. This will prevent the build-up of harmful gas inside your cooker and kitchen.
What is flame failure device in hob?
Post by : admin. Safety device / FFD is used in gas hobs to prevent the accidental gas leakage. In case if while cooking the flame goes off then safety device / FFD immediately cuts off the gas supply to the burner.
What is a flame failure system in a Type A gas appliance?
A Flame Supervision Device (or FSD) or Flame Failure Device (FFD) is a part of the gas burner system that ensures that the fuel supply to a gas appliance such as a gas hob is cut off automatically and immediately if for any reason the flame goes out or becomes unstable.
What is a thermocouple flame failure device?
A flame failure device is responsible for shutting off the gas supply in your cooker if the flame is extinguished for any reason. The thermocouple on your gas cooker is responsible for closing the gas valve to help prevent gas leaks.
What is flame failure protection?
For gas appliances, a flame supervision device (FSD) – alternative name: flame failure device (FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished.
What is a flame rectification system?
In a nutshell, the flame rectification system is an electrical process that causes a low level DC current to be conducted from the flame rod through the flame, and back to ground. Technicians can measure this flame current by placing a meter that measures DC microamps in series with the flame rod.
What is a flame failure valve?
Basically flame failure technology is designed to prevent the build up of large amounts of unignited gas if the pilot system goes out. Flame failure devices are can be used on gas appliances for other burners not just the oven, such as open tops, concealed hot tops and griddle burners.
Is a thermocouple a flame failure device?
