2. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   The flame temperature is high, about 2,000 °C for hydrogen gas in air at atmospheric pressure, [11] and up to 2800 °C when pre-mixed in a 2:1 ratio with pure oxygen (oxyhydrogen). Hydrogen is not used for welding steels and other ferrous materials, because it causes hydrogen embrittlement .

3. Blowtorch - Wikipedia

   en.wikipedia.org/wiki/Blowtorch

   Oxyacetylene torch; Liquid, with ambient atmospheric air after vaporizing it using a coiled tube passing through the flame. They take time to start, needing pre-heating with burning methylated spirit: kerosene as described in Carl Richard Nyberg's patent of 1882: a simple heating torch using liquid fuel (such as kerosene (US) / paraffin oil (UK ...

4. Acetylene - Wikipedia

   en.wikipedia.org/wiki/Acetylene

   Acetylene is a moderately common chemical in the universe, often associated with the atmospheres of gas giants. [50] One curious discovery of acetylene is on Enceladus, a moon of Saturn. Natural acetylene is believed to form from catalytic decomposition of long-chain hydrocarbons at temperatures of 1,700 K (1,430 °C; 2,600 °F) and above ...

5. Thermal lance - Wikipedia

   en.wikipedia.org/wiki/Thermal_lance

   Simplified principle and graph of temperature (T) vs distance from the reacting tip (d) of a thermal lance [1] One end of the tube is placed in a holder and oxygen is fed through the tube. The far end of the tube is pre-heated and lit by an oxyacetylene torch.

6. Oxy-fuel combustion process - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_combustion_process

   Almost all of the nitrogen is removed from input air, yielding a stream that is approximately 95% oxygen. [3] Firing with pure oxygen would result in too high a flame temperature, so the mixture is diluted by mixing with recycled flue gas, or staged combustion. The recycled flue gas can also be used to carry fuel into the boiler and ensure ...
