In general, the higher the amount of oxygen per unit volume of air supplied to the burner of combustion equipment that requires high temperatures, such as melting glass, forging steel materials, and firing ceramics, the better the combustion efficiency. For this reason, in the past, oxygen gas from oxygen cylinders or liquid oxygen was supplied to the air. However, since such oxygen is expensive, it is not preferable to use them. In addition, in recent years, in order to increase the oxygen content in the air, that is, to obtain oxygen-enriched air, a polymer membrane is used and air is permeated through the polymer membrane, which increases the oxygen concentration in the atmosphere. 21% by volume) to 23-31% by volume, and there is interest. As the polymer membrane mentioned above, silicone polymer membranes are beginning to be put into practical use. However, in this method, atmospheric air is passed through a polymer membrane, so it is difficult to obtain a large amount of oxygen-enriched air at once. The disadvantage is that it requires a fairly large-scale device.

Generally, the amount of dissolved air increases as the pressure increases, but of the main air constituents, nitrogen, oxygen, and hydrogen, oxygen dissolves best in perfluorocarbons, and the content of oxygen in dissolved air is the highest. It will look like Figure 2. For example, the oxygen content in the atmosphere is about 21% by volume, but in perfluorocarbons under pressure there are some differences depending on the type of perfluorocarbon, but at about 4 atmospheres the oxygen content in dissolved air is The content (concentration) is approximately 27% by volume, and at 10 atmospheres it is approximately 29% by volume, after which the oxygen content does not increase much even if the pressure is increased.

Therefore, if air is introduced into perfluorocarbon under pressure and the air is dissolved by utilizing the above-mentioned solubility characteristics of air and the oxygen contained therein in perfluorocarbon, up to 30% by volume of oxygen can be dissolved. When the pressurized air-dissolved perfluorocarbon is returned to atmospheric pressure (1 atmosphere), the air dissolved in the perfluorocarbon is released from the perfluorocarbon. The oxygen component in the air released at this time will have a high content of up to about 29% by volume if the pressure is 10 atmospheres or more during dissolution.

The content of oxygen in the air released at this time is approximately 27% by volume, and as a result, air with a higher oxygen content than that of normal air, ie, oxygen-enriched air, is obtained. The above pressure is 10
If the pressure is above atmospheric pressure, oxygen-enriched air with an oxygen content of about 29% by volume or more can be obtained.
