A red or yellow flame is a flame being starved of oxygen, creating incomplete combustion. The flame will be at a much lower temperature and will seem more sooty. The yellow colour comes from the soot particles produced by the flame. This flame is dangerous as it produces more poisonous carbon monoxide gas.
What does yellow flame indicate?
FLAME INDICATES EFFICIENCY 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 .
How do you fix a yellow flame on a gas stove?
Gas burners burn blue if the ratio of fuel to air is correct. A yellow burner flame is a symptom that the burner is not getting enough air for complete combustion of the gas. Correcting this problem involves adjusting the burner’s air shutter to admit more air, something that an experienced do-it-yourselfer can do.
