  2. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1,950 °C (2,220 K; 3,540 °F). [citation needed] This is mostly because the heat of combustion of these compounds is roughly proportional to the amount of oxygen consumed, which proportionally increases the amount of air that has ...

  3. Flame - Wikipedia

    en.wikipedia.org/wiki/Flame

    Dicyanoacetylene, a compound of carbon and nitrogen with chemical formula C 4 N 2 burns in oxygen with a bright blue-white flame at a temperature of 5,260 K (4,990 °C; 9,010 °F), and at up to 6,000 K (5,730 °C; 10,340 °F) in ozone. [10]

  4. Fire - Wikipedia

    en.wikipedia.org/wiki/Fire

    Fire. A burning candle. Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [ 1][ a] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.

  5. Colored fire - Wikipedia

    en.wikipedia.org/wiki/Colored_fire

    Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam. When additional chemicals are added to the fuel burning, their atomic emission spectra ...

  6. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.

  7. Pyrotechnic colorant - Wikipedia

    en.wikipedia.org/wiki/Pyrotechnic_colorant

    Sodium compounds glow yellow in a flame. A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction.

  8. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    The flame temperature is high, about 2,000 °C for hydrogen gas in air at atmospheric pressure, [11] and up to 2800 °C when pre-mixed in a 2:1 ratio with pure oxygen (oxyhydrogen). Hydrogen is not used for welding steels and other ferrous materials, because it causes hydrogen embrittlement .

  9. Flame test - Wikipedia

    en.wikipedia.org/wiki/Flame_test

    A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis. The phenomenon is related to pyrotechnics and atomic emission spectroscopy. [ 1] The color of the flames is understood through the principles ...
