本考案は湯沸器等に用いるブンゼン式スリツト
バーナに関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a Bunsen-type slit burner used in water heaters and the like.
（従来の技術およびその問題点）
従来のブンゼン式スリツトバーナとしては例え
ば第４図に示すものがある。(Prior Art and its Problems) As a conventional Bunsen type slit burner, there is one shown in FIG. 4, for example.

ある。 This burner a has flame opening slits d on the upper side of the burner head c of the vertical flattened body b, and flame-stabilizing air-fuel mixture outlets e arranged on the outer side thereof in the longitudinal direction of the body b. This is a configuration in which a flame stabilizing plate f is provided opposite the air-fuel mixture outlet e. In the conventional burner a having such a configuration, when gas and air are fed into the vessel b through a nozzle, they mix together to form a gas-air mixture, most of which is ejected from the flame opening slit d to form the main flame. At the same time, a part of it flows out from the flame-holding air-fuel mixture outlet e and ascends the gap between the outer surface of the vessel body b and the flame-holding plate f,
It burns above it to form a stable flame.
しかるに、このような構成の従来バーナａのバ

このため二次空気を有効に利用できず、燃焼性が
悪いという問題点がある。 However, the burner head c of the conventional burner a having such a configuration, for example, as shown in FIG. 4b,
Since its upper surface is flat, the proportion of secondary air flowing from bottom to top hitting flame g along the outer wall of burner a, indicated by the arrow in the figure, is relatively small.
Therefore, there is a problem that secondary air cannot be used effectively and combustibility is poor.

たり易くなるので、大きな燃焼音が発生し、これ
が不快な騒音源になる、という問題点がある。 As another structure, for example, as shown in Fig. 4c, there is a structure in which the upper surface of the burner head c is formed into a semicircular shape, but in such a structure, the flame g spreads laterally, so that the secondary air is The proportion of contact with the flame g is large, and therefore the poor combustibility, which is a problem with the flat top surface described above, can be improved, but on the other hand, it becomes easier for the secondary air to directly contact the inner flame h. However, there is a problem in that a loud combustion noise is generated, which becomes a source of unpleasant noise.

を目的とするものである。 As described above, the present invention arranges flame opening slits on the upper side of the burner head of the conventional vertical flatware body, and flame-stabilizing air-fuel mixture outlets on the outer side of the burner head in rows in the longitudinal direction of the body. At the same time, the Bunsen-style slit burner, which has a flame-holding plate facing the air-fuel mixture outlet, was required to maintain good combustibility without impairing the flame-holding effect, while minimizing the generation of combustion noise. The purpose is to solve problems.

To explain based on the drawings, the Bunsen type slit burner 1 of the present invention has a flame opening slit 4 on the upper side of the burner head 3 of the vertical flattener body 2, and a flame-stabilizing mixture outlet 5 on the outer side thereof. Vessel 2
In the burner 1, the upper surface of the burner head 3 is arranged in a row in the longitudinal direction, a flame stabilizing plate 6 is provided opposite the air-fuel mixture outlet 5, and a flame stabilizing formation part 7 is formed above the flame stabilizing plate 6. It is formed into a mountain shape to constitute a mountain slope 8, and the outer end 9 of the flame opening slit 4 is located above the flame holding formation part 7.

定化するための保炎１２を形成する。(Operation and Examples) To explain the operation of the present invention together with an example, the burner 1 of the present invention has the following feature: When gas and air are fed into the vertical flattener body 2 through the nozzle 10, they mix with each other, resulting in a gas-air mixture. Most of it ejects from the burner slits 4 arranged in the burner head 3 and burns, forming the main flame 11, while a part of it flows out from the flame-holding mixture outlet 5 and burns the flame. The flame holding plate 6 moves upward through the gap between the outer surface of the main flame 2 and the flame holding plate 6, and burns in the upper flame holding forming part 7, forming a holding flame 12 for stabilizing combustion of the main flame.

つて高ターンダウン比を得ることができる。 Therefore, the burner head 3 of the burner 1 of the present invention
Since the upper side is formed into a mountain shape in the transverse direction to form a mountain slope 8, the flame opening slits 4 arranged in a row on the upper side of the burner head 3 are in a state where the outer end 9 is inclined downward. become. Therefore, in the flame opening slit 4, as shown in FIG.
The inner flame 13 and outer flame 14 of the main flame are in a state where they are ejected at a slight angle to the outside from directly above the burner 1, so they are ejected along the outer wall of the burner 1 as indicated by the arrow in the figure.
The secondary air flowing from the bottom to the top hits the outer flame 14 more efficiently than when the upper side of the burner 1 is flat, so it is possible to maintain good combustibility. Since the ratio of the upper surface to the upper surface is relatively smaller than that in the case where the upper surface is configured in a semicircular shape, combustion noise can be suppressed to a low level. In this way, since the amount of secondary air that hits the inner flame 13 is relatively small, lift is less likely to occur, and therefore a high turndown ratio can be obtained.

することができる。 Moreover, in the present invention, since the outer end 9 of the flame opening slit 4 is located above the flame-holding formation part 7, a state in which the flame-holding 12 and the main flame 11 overlap and burn, that is, the main flame 11 Since an adverse effect on the flame holding 12 can be avoided, a stable flame holding effect can be achieved.

In the Bunsen type slit burner, a flame stabilizing plate is provided opposite the air-fuel mixture outlet, and a flame stabilizing portion is formed above the flame stabilizing plate.
This has the effect of suppressing the generation of combustion noise, improving combustibility, and realizing stable combustion with a high turndown ratio that is difficult to lift.
