The present invention relates to a primary air supply apparatus for a gas burner, that is, to a primary air supply apparatus for a plurality of gas burners adjacently placed in advance.

Since the primary burner of gas burner is large and small depending on the type of gas, the damper is used as the primary blower according to the type of gas by means of a damper. When a plurality of such gas burners are installed adjacent to each other, it is convenient for shafts to be used for common shafts, but the dampers are polymerized, so that the dampers are polymerized. A gap occurs in the air, and there is a defect that air is sucked through it.

On the other hand, adjacent burners are not necessarily the same size of the primary air tool even in the same gas type, but rather the size of the primary air tool is often different for the following reasons. That is, for example, when two burners are formed and configured in a strong and weak switch type, gas consumption is less toward one burner, and thus a primary air tool is also small. For example, two infrared burners may be installed at the top and bottom. Even if the lower burner has the same heating capacity, the upper burner is affected by the lower burner, so the gas consumption on the lower burner side is smaller, and thus the primary burner of the lower burner is smaller than that of the lower burner.

Therefore, the inventors of the present invention have a small influence on the amount of primary air in the burner having a small primary air tool. However, the change in the small amount of air has a large effect. In view of the fact that the size of the primary air tools as described above are often different, the primary air supply apparatus without the above-mentioned defects is devised.

It will be described in detail with reference to the drawings. Burners (1) and (2) are combustion plates (8) and (9) having mixing tubes (3) and (4), mixing chambers (5) and (6), and a plurality of flame holes (7), respectively. It forms a normal with and consists of two stages up and down adjacent. In this example, the mixing tube 3 of the upper burner 1 penetrates the mixing chamber 6 of the lower burner 2, and the combustion plates 8 and 9 are burner in the same area. The heating capacity of (1) and (2) is the same.

The gas supply case 10 of the burner 1 and the gas supply case 11 of the burner 2 are formed in the primary air tools 12 and 13, respectively. Although the primary air tools 12 and 13 are set to the respective dampers 14 and 15, the primary air holes 12 and 13 are different in size even in the same gas type. As described on the previous page, for example, even if two burners have the same heating capacity, if the burner is adjacent to the burner up and down as in this embodiment, the upper burner 1 is affected by the heat of the lower burner 2. It is at least as small as the gas consumption of the honorer 2, and therefore the primary air amount is also small. Therefore, the primary air tool 13 is configured to be smaller than the primary air tool 13 of the burner 2 below.

The dampers 14 and 15 are axially supported by a common shaft 16, and the dampers 14 of the small primary air 12 are lower than the dampers 15 of the large primary air mechanism 13. Supported. Reference numeral 17 denotes a gap between the gas supply case 10 and the lid 18 of the gas supply cases 10 and 11 generated by the damper 15 of the large primary air tool 13 being axially supported above the damper 14. Numeral 19 denotes a rotation knob of the damper, numeral 20 denotes a stopper, numeral 21 denotes a nozzle insertion hole.

The present invention is constructed as described above and the primary air is supplied by gas injection from a gas nozzle (not shown), but the damper 14 of the primary air mechanism 12 of the burner is lower than the other dampers 15. Therefore, the damper 14 is in close contact with the lid 18, and there is no gap, and the primary air is sucked only by the primary air tool 12 to provide an appropriate primary air supply.

On the other hand, the suction of the primary air of the burner 2 is performed not only through the primary air mechanism 13, but also through the gap 17 as a dashed-dotted line (FIG. 3), and the suction primary air is discharged from the set primary air mechanism. That's a bit more than that.

However, in the present invention, since the damper 14 is lower than the other damper 15 so that a gap does not occur in the side of the small primary air tool 12 which is affected even by a slight change in the suction air amount, only the primary air tool 12 is used. Aspirated to provide proper primary air supply.

In addition, even if the gap 17 generated by the polymerization of the dampers 14 and 15 is located on the side of the large primary air mechanism 13, a large amount of primary air is supplied to the burner, so that a slight increase in the primary air has little effect. none.

As described above, since the primary air tool has the damper 14 as the lower side of the damper in supporting the small damper 14 and the large damper 15 by the common shaft 16, the primary air tool is In small burners, adequate primary air is supplied for good combustion.

Claims (1)
