Oxygen-enriched air is supplied from the machine 3 to the burner 7 via a flow path 6. As a result, the gaseous or liquid fuel supplied to the burner 7 from the stream Wt8 is combusted. The downstream flow Wilt 5 #i of the direct air pump 2 is connected via the flow path 9 to the upstream flow path 4 of the vacuum pump 2 . Waku14119
A flow plow control valve lO is interposed in the fil.
The throttle kk of the IT control valve 10 is controlled by the control circuit 1i1)ill. This control circuit 11 is given a signal from a detector 12 that detects the oxygen concentration of the air in the flow path 6 . The control circuit 11 connects the burner 7 through the flow path 6.
The throttle of the flow rate control valve 10 is controlled so that the oxygen concentration of the air supplied to the flow rate control valve 10 becomes a predetermined value.

圧送される。When the flow control valve 10 is closed, the pressure in the flow path 4 is, for example, −600 mmHf due to the action of the vacuum pump 2, and the pressure in the flow path 5 is approximately atmospheric pressure. By the blower 3, the flow path 6
For example, about 300 mmAq of air is fed under pressure to the burner 7.

るようになる。When the oxygen concentration of the air flowing through the flow path 6 detected by the detectors 1 and 2 is lower than a predetermined value, the control circuit 11 increases the throttle amount of the flow rate control valve 10 to close the flow path 5.
The flow rate of air returned from the air through the flow path 9 to the flow path 4 is reduced. As a result, the flow rate of air passing through the oxygen enrichment membrane 1 is increased, and air having a predetermined oxygen concentration is supplied to the cooler 7.

供給することができる。When air containing high concentration of oxygen is supplied to the burner 7 from the flow path 6, K reduces the restriction violet of the flow rate control valve 10 to allow air to flow from the flow path 5" to the flow path 4 through the flow path 9. The air at the edge of the main stream is removed.This reduces the air flow rate filling the oxygen enrichment membrane 1 and allows the burner 7 to be supplied with air having a predetermined acid A concentration.

る。In order to concentrate and separate air through the oxygen enrichment membrane 1 to obtain a high oxygen concentration in the flow path 4, oxygen enrichment lI@1 is required.
(r) 1 A pressure difference must be provided between the first side and the rear side.Since the permeation flow capacity is proportional to the pressure difference, the larger the pressure difference, the larger the Urawa will be.Therefore, the upstream of the oxygen enrichment membrane 1 It is considered preferable to pressurize the air from the side (left side in FIG. As soon as this begins, polarization of the poorly permeable gas occurs on the test surface, which inhibits the separation of oxygen from the air.To prevent this, - new air must be constantly fed to the surface.Therefore, the nitrogen-enriched membrane If pressurized air is supplied to oxygen enrichment membrane 1, most of the pressurized gas will be discarded, which is not preferable from the viewpoint of energy saving. Although the difference is small, it can be seen that the induction using the vacuum pump 2 is superior in terms of energy saving and energy consumption.

の酸素濃度を変えることができる。The oxygen concentration of the air in the flow path 4 that permeates through the oxygen enrichment membrane 1 increases as the amount of air that permeates increases. Therefore, as described above, by changing the throttle amount of the flow rate control valve 1O, the oxygen concentration of the air delivered from the blower 3 to the flow path 6 can be changed.

なくなる。Corresponding parts of the above-described embodiments are designated by the reference numeral Vifii-. In order to keep the oxygen concentration of the air supplied to the H1 burner 7 constant in this embodiment, the control circuit 11 controls the detector 1
In response to the output from the air blower 2, air is mixed into the flow path 5 on the upstream side of the blower 3 via the flow path 14 by controlling the amount of restriction by the flow rate control valve 13. According to such an embodiment, it is possible to suppress an excessive increase in the oxygen concentration of the oxygen-enriched air supplied to the burner 7,
Therefore, there is no need to unnecessarily improve the heat resistance of the burner 7.

る。As described above, according to the present invention, part of the air from the attracting means is returned to the upstream side of the attracting means to control the oxygen concentration of the oxygen-enriched air supplied to the burner. It becomes possible to continuously control the temperature of the burner with a simple configuration.In addition, in the present invention, air is supplied to the burner by four people in the middle of the flow path that guides air from the induction means to the burner. Since the flow rate of the air is controlled, there is no need to pass a large amount of air through the oxygen-enriching membrane, and the size of the induction stage can be reduced. It is advantageous to supply air with 4 degrees of oxygen to the burner, and there is no need to unnecessarily improve the heat resistance of the burner.
