A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, ...
The gas burner has many applications such as soldering, brazing, and welding, the latter using oxygen instead of air for producing a hotter flame, which is required for melting steel. Chemistry laboratories use natural-gas fueled Bunsen burners. In domestic and commercial settings gas burners are commonly used in gas stoves and cooktops.
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.
The Teclu burner vs. the Amal burner: The Amal burner is a burner created by the modification of the Bunsen and Teclu burner. The Amal burner was marketed by Messrs. Amal Ltd., of Birmingham. In this burner, a needle valve is inserted in the orifice of the jet to sensitively control the gas flow into the burner by an external screw.
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.
It is well established that conventional "blue flame" or bunsen gas burners produce oxides of nitrogen at levels of 30-50 nanograms per joule [5] [6] and are as such not considered to have potential for NO x reduction. Surface combustion burners or radiant tile burners in comparison produce nitrogen oxides' levels 60-70% less. [6]

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]
