Burning temperature of oxygen

Oxyhydrogen will combust when brought to its autoignition temperature. For the stoichiometric mixture, 2:1 hydrogen:oxygen, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). The minimum energy required to ignite such a mixture, at lower temperatures, with a spark is about 20 microjoules. At standard temperature and pressure, oxyhydrogen can burn when it is between about 4% and 95% hydrogen by volume.

WebPropane, when burned in air, will burn at a temperature of around 1,960 degrees Celsius or 3,560 degrees Fahrenheit. If, on the other hand, it is burned with a pure oxygen mix (as it is in some welding and cutting operations) it will burn even hotter, and the flame can be as hot as 2,820 degrees Celsius or 5,108 degrees Fahrenheit. WebOxy-fuel combustion is the process of burning a fuel using pure oxygen, or a mixture of oxygen and recirculated flue gas, instead of air. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible.
