Laminar Flame generated by the burning of a candle. | | Another candle flame | | Flame (disambiguation) | fire | exothermic | combustion | oxidation | reaction | color | temperature | fuel | lighter | candle | molecules | vaporize | oxygen | air | heat | exothermic | free radicals | energy | electrons | light | electromagnetic radiation | blackbody | oxygen | Hydrogen | chlorine | hydrogen chloride | hydrazine | nitrogen tetroxide | hypergolic | rocket engines | chemical kinetics | radicals | natural gas | diffusion flame | premixed flame | evaporation | laminar | Different flame types of a Bunsen burner depend on oxygen supply. On the left a rich fuel with no premixed oxygen produces a yellow sooty diffusion flame; on the right a lean fully oxygen premixed flame produces no soot and the flame color is produced by molecular radicals, especially CH and C2 band emission. The purple color is an artifact of the photographic process | | Bunsen burner | band emission | Spectrum of the blue (premixed, i.e., complete combustion) flame from a butane torch showing molecular radical band emission and Swan bands. Note that virtually all the light produced is in the blue to green region of the spectrum below about 565 nanometers, accounting for the bluish color of sootless hydrocarbon flames. | | butane | radical | Swan bands | A flame test for sodium. Note that the yellow color in this gas flame does not arise from the blackbody emission of soot particles (as the flame is clearly a blue premixed complete combustion flame) but instead comes from the spectral line emission of sodium atoms, specifically the very intense "sodium D lines". | | flame test | sodium | spectral line | color | blackbody radiation | spectral band | spectral line | hydrocarbon | laboratory | gravity | Bunsen burner | incandescence | soot | ionize | butane | molecular | visible spectrum | blow torch | candle | oxyacetylene | Cyanogen | blackbody radiation | In zero gravity, convection does not carry the hot combustion products away from the fuel source, resulting in a spherical flame front. | | zero gravity | National Aeronautics and Space Administration | United States | gravity | microgravity | zero gravity | outer space | convection | NASA | diffusion flames | Earth | applied science | industry | fuel efficiency | National Aeronautics and Space Administration | Categories | Fire |
