∙ 13y agoA laboratory gas burner having a vertical metal tube into which the gas is led, with a hole in the side of the base of the tube to admit air. The amount of air can be regulated by a sleeve on the tube. When no air is admitted the flame is luminous and smoky. With air, it has a faintly visible hot outer part (the oxidizing part) and an inner blue cone where combustion is incomplete (the cooler reducing part of the flame). The device is named after Robert robert-wilhelm-bunsen-1, who used a similar device (without a regulating sleeve) in 1855

The hotter the flame, the less color (and light) given off. Bright, yellow flames are the result of carbon that has not been burned, where blue flames indicate a near total burning of the fuel. Other chemicals present in the wood can color flames- sometimes added for the appearance- red, yellow, blue, green.

What does a blue flame mean in a gas fireplace?
Blue flames can be an indicator of temperature, because blue flames burn hotter than yellow flames, or it could be a chemical that burns blue. Something else that could create blue flames in a gas fireplace is if the air-to-gas mixture ratio is off, more air means bluer flames.
