Bunsen burner

Physics

A 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 Bunsen, who used a similar device (without a regulating sleeve) in 1855.

Chemical Engineering

A type of burner used in laboratories that has a vertical metal tube through which gas is fed. There is a sleeve around a hole near the base used to regulate the amount of air to be mixed with the gas. Adjustment can provide a low-temperature smoky and luminous yellow flame through to an intense high-temperature flame with a blue inner cone. The burner is named after German chemist Robert Wilhelm Bunsen (1811–99).
