Oxy-fuel
From Wikipedia, the free encyclopedia
Oxy-fuel refers to technology that burns oxygen with gaseous fuel. As compared to air, which contains 20.95% oxygen, higher temperatures can be reached using pure oxygen. Approximately the same total energy is produced when burning a fuel with oxygen as compared to with air; the difference is the lack of temperature diluting inert gases. The most common fuel burned in a torch with oxygen is acetylene; even though it presents special handling problems, it has the greatest heat output.
