Question

How does the standing-pilot system provide a safety check for the continually lit pilot?

Select one:
O A. The pilot flame impinges on the thermocouple.
O B. The pilot flame has no safety check.
OC. The pilot flame is located on a runner leading to the burners.
OD. The pilot runner impinges on the flame.

Answer 1

The standing-pilot system ensures safety by using a thermocouple to monitor the pilot flame and control the gas supply to the burner.

Step-by-step explanation:

The standing-pilot system provides a safety check for the continually lit pilot through the use of a thermocouple.

When the pilot flame is lit, it impinges on the thermocouple, which generates a small electric current. This electric current keeps the gas valve open, allowing gas to flow to the burner. However, if the pilot flame goes out for any reason, the thermocouple will cool down and stop generating the electric current. This causes the gas valve to close, preventing any gas from flowing and therefore eliminating the risk of a gas leak and potential explosion.
