How does a flame sensor work in home furnaces by using a metal rod in the flame?
43shifty
Its not a flamesensor its a pilot generater it generates a small amound of electricity to open the main valve that way if your pilot light goes out it wont let gas escape and couse a potentian explosion
The above answer is not accurate unless you have a standing pilot model furnace. Then the "flame sensor is called a thermocouple, much different than the flame sensors used in Direct Spark Ignition, hot-surface and intermitant ignition furnaces.
The flame sensor uses the flame of the main burner to prove flame at the circuit board by measuring conductivity to ground through the flame.

What effect does the nitrate ion have on the color of the flames?
None. Using flame spectral analysis, we can use a prism or other device to determine the color of various metals. Nitrate gives no color. The purpose of the test is to give metal detection, qualitatively. Testing for nitrate is another test, not involving flame.
