  2. Propane torch - Wikipedia

    en.wikipedia.org/wiki/Propane_torch

    A propane torch is a tool normally used for the application of flame or heat which uses propane, a hydrocarbon gas, for its fuel and ambient air as its combustion medium. Propane is one of a group of by-products of the natural gas and petroleum industries known as liquefied petroleum gas (LPG). Propane and other fuel torches are most commonly ...

  3. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    Propane does not burn as hot as acetylene in its inner cone, and so it is rarely used for welding. [12] Propane, however, has a very high number of BTUs per cubic foot in its outer cone, and so with the right torch (injector style) can make a faster and cleaner cut than acetylene, and is much more useful for heating and bending than acetylene.

  4. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    In daily life, the vast majority of flames one encounters are those caused by rapid oxidation of hydrocarbons in materials such as wood, wax, fat, plastics, propane, and gasoline. 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]

  5. Thermite - Wikipedia

    en.wikipedia.org/wiki/Thermite

    Even when the thermite is hot enough to glow bright red, it does not ignite, as it has a very high ignition temperature. [33] Starting the reaction is possible using a propane torch if done correctly. [34] Often, strips of magnesium metal are used as fuses. Because metals burn without releasing cooling gases, they can potentially burn at ...

  6. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    Hand soldering is typically performed with a soldering iron, soldering gun, or a torch, or occasionally a hot-air pencil. Sheetmetal work was traditionally done with "soldering coppers" directly heated by a flame, with sufficient stored heat in the mass of the soldering copper to complete a joint; gas torches (e.g. butane or propane) or ...

  7. Thermal lance - Wikipedia

    en.wikipedia.org/wiki/Thermal_lance

    Uses. cutting, heavy demolition. A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to ...

  9. Gas burner - Wikipedia

    en.wikipedia.org/wiki/Gas_burner

    Propane burner used with forced air into a metal melting furnace. A gas burner is a device that produces a non-controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as the ambient air or supplied oxygen, and allowing for ignition and combustion . The flame is generally used for the heat, infrared ...
