Combustion is the combination of fuel, an oxidizer, and an input energy source such as heat (i e spark plug) as shown by the combustion triangle In the case of many reactions such as hydrocarbon fuels, this oxidizer would be oxygen (in most cases in the form of air), which requires a low input energy to create a chemical reaction

To prevent hypoxia in military or civil air crew, it is necessary to maintain the minimum PPO2 (partial pressure of oxygen in the air) to the level equivalent to that is in sea level (say below 500 meters) in order to let them perform normally In practice the life support system of military and civil aircraft maintain PPO2 by increasing the oxygen concentration of the pilot’s breathing gas supply between the minimum and maximum level

CanGas® Mobile PSA oxygen making & filling trailer can help ground crews fulfill routine or emergency oxygen filling operation at airport with its good mobility and fast production

Dissolved oxygen content in the water of fish ponds is one of the most important parameters of water quality, as the oxygen is a vital condition for all the organisms living in water and having an aerobic type of respiration
