  2. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  3. Fire triangle - Wikipedia

    en.wikipedia.org/wiki/Fire_triangle

    Combustion is a chemical reaction that feeds a fire more heat and allows it to continue. Once a fire has started, the resulting exothermic chain reaction sustains the fire and allows it to continue until or unless at least one of the elements of the fire is blocked: foam can be used to deny the fire the oxygen it needs

  4. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    The closest will be the hottest part of a flame, where the combustion reaction is most efficient. This also assumes complete combustion (e.g. perfectly balanced, non-smoky, usually bluish flame). Several values in the table significantly disagree with the literature [ 1 ] or predictions by online calculators.

  5. Rube Goldberg machine - Wikipedia

    en.wikipedia.org/wiki/Rube_Goldberg_machine

    The Chain Reaction Contraption Contest [6] is an annual event hosted at the Carnegie Science Center in Pittsburgh, Pennsylvania in which high school teams each build a Rube Goldberg machine to complete some simple task (which changes from year to year) in 20 steps or more (with some additional constraints on size, timing, safety, etc.).

  6. Barking dog reaction - Wikipedia

    en.wikipedia.org/wiki/Barking_dog_reaction

    In simple terms, the 'Barking Dog' reaction is a combustion process, in which a fuel (carbon disulfide, CS 2) reacts with an oxidizing agent (nitrous oxide, N 2 O), producing heat and elemental sulfur. The flame front in the reaction is a zone of very hot, luminous gas, produced by the reactants decomposing. 8 N 2 O + 4 CS 2 → S 8 + 4 CO 2 ...

  7. 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.

  8. 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.

  9. Fire - Wikipedia

    en.wikipedia.org/wiki/Fire

    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.
