If you replace it with one with a capacity of 10,000kcal/h and burn it, the spray amount and combustion air supply conditions will deteriorate.
A combustion flame with its root in the flame holder is not formed and causes a lifting phenomenon or blows out, which is dangerous and does not result in complete combustion.
Accompanied by generation of CO and odor. Also, conversely, 10000kcal/h
30000kcal/h of spray nozzle with burner by combination of spray nozzle and frame holder compatible with
If the flame holder is replaced with one with a capacity of It was necessary to solve the problem of eliminating the drawbacks of

して設けられている。 In Fig. 2, 1 is a blower, 2 is a blower tube, 3 is a spray nozzle, 4 is a frame holder, 5 is a retainer, 6 is a spark plug, and the frame holder 4
The periphery of the mounting board 7 is connected to the opening 2 of the blower tube.
It is fixed on the inner circumference closer to 1 . The frame holder is connected to the central through hole 4 1 and has a cut-and-raised piece 4 2 having a square cross-section.
are arranged radially. The above configuration is the same as the conventional one, but a retainer 5, which is the main point of the present invention, is attached to the back side of the frame holder 4 at a predetermined gap L, and the retainer 5 is attached to the third
As shown in the exploded perspective view, the peripheral side wall 5' is curved,
The front end opening 5 1 has a large diameter, and the opening 5 2 at the center of the back has a small diameter. an opening 5 2 at the center of the back surface of the retainer;
There is a predetermined distance from the tip of the spray nozzle 3, and the tip of the spark plug 6 is positioned from the center opening 52 of the retainer 5 to the periphery of the through hole 41 of the frame holder 4.

保持して配設されている。 In FIG. 2, the through hole 4 of the frame holder 4
The diameter d of 1 is the central opening 5 on the back of the retainer 5. The diameter d of 2 is 3.
The diameter d 3 of the central opening 5 2 is smaller than the diameter d 2 of the outer circumference of each cut-and-raised piece of the frame holder,
The relationship is d 1 <d 3 <d 2 , and there is the gap L between the frame holder and the retainer. In this way, the frame holder 4 and the retainer 5 are arranged in a constant relationship.

燃焼が継続する。<Function> The gun-type burner of the present invention having the above configuration operates as follows. In the case of combustion with a small spray amount as shown in Fig. 4, the atomized fuel ejected from the tip of the nozzle is directed to the base side of each radial cut-and-raised piece 42 of the frame holder 4, that is, the center transparent part, as shown in Fig. 4. Hole 4 1
The base of the combustion flame A 1 is formed near the circumference of the flame A 1 and it burns. This is because the outer periphery of each cut and raised piece of the frame holder 4 is blocked by the back plate of the retainer 5 on the back side, so although there is a flow of air from the blower passing through the gap L, The flow velocity is slower than that in the center where it travels almost straight, and vortices are also formed, so the combustion flame in the center is not blown away, and it helps mix the atomized fuel and air in that part, allowing smooth combustion to continue. .
次に燃料噴霧量を増加させてゆくと、燃焼は、
フレームホルダ4の切起し片42の内周基部側だ

きる。 Next, as the amount of fuel spray is increased, the combustion becomes
The flame holder 4's cut-and-raised piece 4 2 cannot be completely burned only on the inner periphery base side, and the base of the combustion flame gradually expands from the gap L part to the outer periphery side, and the air supply amount increases, reaching the maximum When the amount of spray is reached and combustion occurs, a combustion flame A2 is formed almost over the entire cut and raised portion as shown in FIG. 5, and stable combustion can be continued at the maximum amount of spray.

A number of air regulating holes 7 are formed in a portion near the outer periphery of the frame holder 4 to rectify the secondary air flow formed in the space formed between the outer periphery of the frame holder 4 and the inner periphery of the blower tube 2.

Similar to the embodiment shown in the figure, in order to form the secondary air into a swirling flow and obtain better mixing of the atomized fuel and the combustion air, the large-diameter outer circumferential portion is bent outward and cut and bent at several places. It has a structure with cut and raised holes.

値を有するバーナである。<Effects> The gun type burner of the present invention having the above-described configuration and operation has the following features in the frame holder 4 in the blast cylinder:
The frame holder has a simple planar donut-like structure, and the diameter d 3 of the central opening 5 2 is larger than the central through hole 4 1 of the frame holder 4 and smaller than the diameter d 2 of the outer circumference of the cut and raised part. By simply installing a gap L on the back side, a stable combustion flame can be formed by increasing the amount of spray from the nozzle 3, making it possible to form a stable combustion flame for large water heaters and proportional control combustion water heaters. This burner has a useful practical value as it can vary the combustion range of the sprayed fuel and form a stable combustion flame regardless of the increase or decrease in the amount of combustion.
