What is Oxy Fuel?

Oxy-fuel combustion is a process where a fuel is burned using pure oxygen (O2) instead of air (which is approximately 21% oxygen and 78% nitrogen). The most common fuel is natural gas, but other fuels like propane, methane, or even coal can be used. The primary benefit is a high flame temperature and the production of a flue gas composed mainly of CO2 and H2O, which can be easily captured for carbon sequestration, making it a key technology in carbon capture and storage (CCS) systems. It is also used in welding, cutting, and other industrial processes requiring high temperatures.
