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.
However, oxy-fuel is a viable alternative to removing CO 2 from the flue gas from a conventional air-fired fossil fuel plant. However, an oxygen concentrator might be able to help, as it simply removes nitrogen. In industries other than power generation, oxy-fuel combustion can be competitive due to higher sensible heat availability. Oxy-fuel ...
Oxyhydrogen is often mentioned in conjunction with vehicles that claim to use water as a fuel. The most common and decisive counter-argument against producing this gas on board to use as a fuel or fuel additive is that more energy is always needed to split water molecules than is recouped by burning the resulting 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.
Methylacetylene-propadiene (MPS) gas is a type of fuel gas used in oxy-fuel welding and cutting torches, comprising a mixture of several gases. MPS gases [ edit ]

The flashback arrestors are suitable for most technical gases (fuel gases) such as acetylene, hydrogen, methane, propane, propylene and butane as well as oxygen and compressed air. Flashback arrestors have to be tested for gas non-return, for tightness and for gas flow by a qualified person depending on the country specific regulations.
Isolation of the fuel from air simplifies the number of chemical reactions in combustion. Employing oxygen without nitrogen and the trace gases found in air eliminates the primary source for the formation of nitrogen oxide (NO x), produces a flue gas composed primarily of carbon dioxide and water vapor; other trace pollutants depend on the fuel ...
