Argand burner

Argand burner

Burner for an oil lamp, in which the wick is in the form of a hollow cylinder, so that air rises both within and outside the flame, procuring more complete oxidation and therefore a brighter light. The addition of a cylindrical chimney creates a greater draught, at the same time promoting steadiness of the flame by preventing side draughts. It was devised by Pierre Ami Argand (1750–1803).

The same principle is used in gas burners where the gas is admitted into the space between two hollow cylinders. This space is closed at the bottom and provided at the top with a series of small holes through which the gas issues.
