The Bunsen/Desaga design generated a hot, sootless, non-luminous flame by mixing the gas with air in a controlled fashion before combustion. Desaga created adjustable slits for air at the bottom of the cylindrical burner, with the flame issuing at the top. When the building opened early in 1855, Desaga had made 50 burners for Bunsen's students.
Robert Wilhelm Eberhard Bunsen (German:; 30 March 1811 [a] – 16 August 1899) was a German chemist.He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. [11]
The high output burner is suitable for boiling a large pot of water quickly, sautéing and searing, while the low output burners are good for simmering. Mean benzene emissions from gas and propane burners on high and ovens set to 350 °F ranged from 2.8 to 6.5 μg min–1, 10 to 25 times higher than emissions from electric coil and radiant ...
Flat burners were invented mainly to distribute gas and light evenly to the systems. 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 ...
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]

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.
Around the time he graduated from the University of Kentucky, the knee pain returned, and he developed an addiction to pain medications. Patrick’s habit built steadily and in secret. He needed a Percocet just to get out the door. After a statewide and federal crackdown on pain pills made them too expensive, he switched to heroin.
