Question

What is the flame color of CO gas?

Answer 1

Answer:

Carbon monoxide may be present if there are any of the following danger signs: Gas flames that normally burn blue burn orange or yellow instead.

Explanation:

The flames on most burners that use a gaseous fuel such as natural gas or liquified petroleum gas should burn steadily with a clear, blue flame, except for special designs such as fireplace logs and torches. A wavering, yellow flame on a normal gas burner indicates that the burner is out of adjustment or the air inlet is restricted. As a result, the burner may be producing excessive amounts of CO. However, the flames in burners that use fuel oil should burn with a clear yellow or orange flame . This is an indication of good combustion in equipment that burns fuel oil.
