Tests [citation needed] showed that an oxy-gasoline torch can cut steel plate up to 0.5 in (13 mm) thick at the same rate as oxy-acetylene. In plate thicknesses greater than 0.5 in (13 mm) the cutting rate was better than that of oxy-acetylene; at 4.5 in (110 mm) it was three times faster. [10]
Reducing, neutral and oxidizing oxyacetylene flames. A flame is affected by the fuel introduced and the oxygen available. A flame with a balanced oxygen-fuel ratio is called a neutral flame.
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.
The investigation by the Civil Aeronautics Board discovered that a fuel leak in the port engine's fuel pump had ignited and the slipstream fanned the flames to a white hot intensity. The ensuing fire, acting like an oxy-acetylene torch, burned through the wingspar and caused the crash. [3] [4] [5] A DC-3 similar to the accident aircraft
The torch used for lead burning is a small, hot, gas flame. Oxy-acetylene is most commonly used, as it is easily portable. A small size #0 nozzle is usually used, sometimes with a miniature torch body, but the torch is otherwise the same as that used for steel or copper work.
Modern versions of differential hardening were developed when sources of rapidly heating the metal were devised, such as an oxy-acetylene torch or induction heating. With flame hardening and induction hardening techniques, the steel is quickly heated to red-hot in a localized area and then quenched. This hardens only part of the object, but ...
While blowing air is effective, blowing oxygen produces higher temperatures, and it is also practical to invert the roles of the gasses and blow fuel through air. Contemporary blowtorches and oxy-fuel welding and cutting torches can be considered to be modern developments of the blowpipe. Kit for blowpipe analysis Carl Osterland, Freiberg, c. 1870
A huge cylindrical gasometer, the largest in the world at that time at 5 million cubic feet (140,000 m 3), developed a leak, and repairmen were sent to fix it. The exact cause of the explosion is not known, but some of those repairing the leak were using acetylene torches. [2] There was a loud explosion, and three gasometers at the site ...
