  2. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    The oxy-acetylene (and other oxy-fuel gas mixtures) welding torch remains a mainstay heat source for manual brazing, as well as metal forming, preparation, and localized heat treating. In addition, oxy-fuel cutting is still widely used, both in heavy industry and light industrial and repair operations.

  3. Oxy-fuel combustion process - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_combustion_process

    The justification for using oxy-fuel is to produce a CO 2 rich flue gas ready for sequestration. Oxy-fuel combustion has significant advantages over traditional air-fired plants. Among these are: The mass and volume of the flue gas are reduced by approximately 75%. Because the flue gas volume is reduced, less heat is lost in the flue gas. The ...

    en.wikipedia.org/wiki/Gas_cylinder

    A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...

    en.wikipedia.org/wiki/MAPP_gas

    A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.

  6. Bottled gas - Wikipedia

    en.wikipedia.org/wiki/Bottled_gas

    Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal gas pressurised to 200 bar in a cylinder would contain 200 times as much as the volume of the cylinder at atmospheric pressure, but real gases will contain less than that by a few percent. At higher pressures, the shortfall is greater.

    Nineteenth-century electrolytic cell for producing oxyhydrogen. Oxyhydrogen is a mixture of hydrogen (H 2) and oxygen (O 2) gases.This gaseous mixture is used for torches to process refractory materials and was the first [1] gaseous mixture used for welding.

  9. Flashback arrestor - Wikipedia

    en.wikipedia.org/wiki/Flashback_arrestor

    A gas non-return valve (NV), which: prevents dangerous gas mixtures. ensures the gas only flows in the intended direction. and a flame arrestor (FA), which: cools the flame to below the ignition temperature of the gas or gas mixture. prevents flashback. In addition to these two basic safety functions a flashback arrestor can also have a:
