  2. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The combustion of methane, a hydrocarbon. In complete combustion, the reactant burns in oxygen and produces a limited number of products. When a hydrocarbon burns in oxygen, the reaction will primarily yield carbon dioxide and water. When elements are burned, the products are primarily the most common oxides.

  3. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    The combustion of a stoichiometric mixture of fuel and oxidizer (e.g. two moles of hydrogen and one mole of oxygen) in a steel container at 25 °C (77 °F) is initiated by an ignition device and the reactions allowed to complete. When hydrogen and oxygen react during combustion, water vapor is produced.

  4. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.

  5. Exothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Exothermic_reaction

    A particularly important class of exothermic reactions is combustion of a hydrocarbon fuel, e.g. the burning of natural gas: CH 4 + 2O 2 → CO 2 + 2H 2 O ΔH⚬ = - 890 kJ/mol Video of an exothermic reaction. Ethanol vapor is ignited inside a bottle, causing combustion. These sample reactions are strongly exothermic.

  6. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    Incomplete reaction at higher temperature further curtails the effect of a larger heat of combustion. [citation needed] Because most combustion processes that happen naturally occur in the open air, there is nothing that confines the gas to a particular volume like the cylinder in an engine.

  7. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Combustion reactions frequently involve a hydrocarbon. For instance, the combustion of 1 mole (114 g) of octane in oxygen + + releases 5500 kJ. A combustion reaction can also result from carbon, magnesium or sulfur reacting with oxygen.

  8. Flame - Wikipedia

    en.wikipedia.org/wiki/Flame

    In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues. Different flame types of a Bunsen burner depend on oxygen supply.

  9. Peters four-step chemistry - Wikipedia

    en.wikipedia.org/wiki/Peters_four-step_chemistry

    The third reaction, known as radical consumption layer, where most of the heat is released, and the first reaction, also known as fuel consumption layer, occur in a narrow region at the flame. The fourth reaction is the hydrogen oxidation layer, whose thickness is much larger than the former two layers.
