What is Oxy-Fuel?
oxy-fuel is fuel burning with pure oxygen instead of a mixture of oxygen, nitrogen and carbon dioxide in the air. When the fuel is burned with pure oxygen, any carbon dioxide content can be stored without having to remove nitrogen, a critical step in the treatment of waste products in power plants. Gases released by power plants are 75% nitrogen, which must be removed from any steam of carbon dioxide. The most prominent application is in coal combustion power plants, but can also be beneficial for most boilers, it can also benefit most boilers, can also be beneficial gas turbine, oxygen production and welding application. The oxy-power combustion process results in coal with much higher combustion temperature, but this can be controlled by mixing oxygen with steam or smoke gas from other plant processes. Nitrogen is present in the boiler only at low levels and low nitrogen oxide or nitric oxide is produced to contaminate the air. Carbon dioxide and water are the main components of the gas that can beconcentrate in the streams of almost pure carbon dioxide. The advantage is that the remaining gas can be compressed, dried and cleaned much faster and cheaper than traditional methods before moving to storage.
The gas turbine cycle is improving using oxy-power, but because the gas turbine blades do not tolerate high temperatures well, turbines require redesign that will work with oxygenated fuel. High -temperature smoke gas leaving a modified turbine actually makes the steam cycle more efficient. The welding and cutting of the oxy-valiva also provides welders more control over how much heat is generated, so the temperature of the welding zone can be maintained at safe levels. The size of the beads welded as a shape is easier to check and the changes needed to use oxy-valiva in welding are relatively simple.
Full Oxy-Paliva applications are still evolving. This technology was a testAnna in the United States, Canada, Europe and Japan and less complexity and the risk of technology is attractive. Requirements for clean combustion of coal plants and energy production equipment that are safer for the environment could cause a large increase in oxygen -based fuel systems during technology. The production of oxygen and separation from air at lower costs than cryogenic methods may also be possible.
