The gap, set by the distance between the nut and the end of the tube, regulates the influx of the air in a way similar to the open slots of the Bunsen burner. The Teclu burner provides better mixing of air and fuel and can achieve higher flame temperatures than the Bunsen burner. [9] [10]
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]
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 ...
The fishtail burner was similar to the flat burner, but it produced a brighter flame and conducted less heat. The last burner that was experimented with was the Welsbach burner. Around this time the Bunsen burner was in use along with some forms of electricity. The Welsbach was based on the idea of the Bunsen burner, still using gas.
The first gas heater made use of the same principles as the Bunsen burner. Beginning in 1881, the burner's flame was used to heat a structure made of asbestos, a design patented by Sigismund Leoni, a British engineer. Later, fire clay replaced the asbestos because it is easier to mold.
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 ...

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. Compared with a Bunsen burner, the lower part of its tube has more openings with larger total cross-section, admitting more air and facilitating better mixing of air and ...
