A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; ... similar in function to the choke in a carburettor.
The burner was introduced by French chemist Georges Méker in an article published in 1905. [1] The Méker burner heating power can be around 3.6 kW using liquefied petroleum gas. [2] Flame temperatures of up to 1,100–1,200 °C (2,000–2,200 °F) are achievable.
Propane burner with a Bunsen flame Oxy-Acetylene for cutting through steel rails Flame of a gas and oil, in a dual burner. A gas burner is a device that produces a non-controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as the ambient air or supplied oxygen, and allowing for ignition and ...
In a Bunsen flame, a steady flow rate is provided which matches the flame speed so as to stabilize the flame. If the flow rate is below the flame speed, the flame will move upstream until the fuel is consumed or until it encounters a flame holder. If the flow rate is equal to the flame speed, we would expect a stationary flat flame front normal ...
Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available. Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner.
A variety of Bunsen burner flames. Bunsen burners may be adjusted from a highly luminous flame (left) to a hotter 'roaring blue flame' (right) One of the most familiar instances of a luminous flame is produced by a Bunsen burner. This burner has a controllable air supply and a constant gas jet: when the air supply is reduced, a highly luminous ...
For this work, Bunsen and his laboratory assistant, Peter Desaga, had perfected a special gas burner by 1855, which was influenced by earlier models. The newer design of Bunsen and Desaga, which provided a very hot and clean flame, is now called simply the "Bunsen burner", a common laboratory equipment. [16] [17]
A laboratory tripod is most commonly used in middle and high schools for basic heating experiments. [2] However, tripods and bunsen burners have been made obsolete by hot plates, which are considered to be safer since there is no direct contact with the flame.
