Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a burner device mainly applied to a combustor that consumes a large amount of gas.

(Prior Art) A conventional burner device of this type is a double burner in which a small capacity burner and a large capacity burner are arranged in double layers inside and outside, and the upper surface of the large capacity burner is provided with a light source from the small capacity burner. It is known to have a flame hole for ignition.

(Problems to be Solved by the Invention) However, as shown in FIGS. 4 and 5, the flame hole for the conventional flame transfer ignition described above has a raised portion b provided on the upper surface of the large capacity burner, for example, the upper surface of the burner cap a. One has a slit c formed on the circumferential surface of the burner cap, and the other has a slit c formed on the upper surface of the burner cap a as shown in Fig. 6. There is an inconvenience that it invades the inside of c and deteriorates the fire transfer performance.

(Means for Solving the Problems) The present invention aims to provide a device that eliminates the above-mentioned disadvantages, and is a dual burner in which a small capacity burner and a large capacity burner are arranged double inside and outside. The large-capacity burner is provided with a flame hole on the upper surface thereof for igniting the flame from the small-capacity burner,
The flame hole is composed of a gas nozzle hole provided on the upper surface of the large-capacity burner, and a cap that can be fitted into and removed from the gas nozzle hole. It is characterized in that it has a slit in its surface and a gas passage inside which communicates the slit with the gas injection hole.

(Function) The present invention has the above-mentioned configuration. According to this, there is an eaves above the slit, so it is difficult for spilled liquid to enter the slit, and even if it does enter the slit, the cap is protected It can be cleaned by removing it from the gas nozzle, so the flame hole can always be maintained in a state with good flame transfer performance.

(Example) Next, an example of the present invention will be described based on the drawings.

In Fig. 1, a burner cap 5 having a plurality of protrusions 4 arranged at appropriate intervals on the lower surface of the outer periphery is mounted on the upper opening of an internal gas distribution chamber 3 connected to the mixing tube 2, and the burner cap 5 is placed within each interval. The simmer burner 7 is a large-capacity burner that acts as a flame hole 6, and the simmer burner 7 is a small-capacity burner that has flame holes 8 made of through-holes arranged at appropriate intervals on its outer circumferential surface.
are arranged inside and outside so that they are located in the inner space of the gas distribution chamber 3 of the main burner 1, thereby forming a double burner.

In the above-mentioned two-burner, the flame intensity of the main burner 1 and the simmer burner 7 can be adjusted proportionally from the minimum to the maximum by adjusting the flames of the main burner 1 and the simmer burner 7 using an operator (not shown), but broadly speaking, the flame intensity can be selected and adjusted in four stages. If both main burner 1 and simmer burner 7 have large flames, the flame intensity will be maximized, if both main burner 1 and simmer burner 7 have small flames, the flame intensity will be medium, and only simmer burner 7 will have a large flame. If so, the fire intensity can be adjusted to a minimum, and if the simmer burner 7 is set to a small flame, the flame intensity can be adjusted to the minimum.

Further, a plurality of flame holes 9 for ignition from the simmer burner 7 are provided on the upper surface of the main burner 1. To explain this specifically, each flame hole 9
The burner cap 5 consists of a gas nozzle hole 10 made of a through hole provided on the top surface of the burner cap 5, and a cap 11 that can be fitted into and removed from the gas nozzle hole 10. As shown in FIG. It has a disk-shaped eave 12 on its surface, and has slits 13 at appropriate intervals on its lower peripheral surface, and each slit 13 is inserted into the gas nozzle hole 1 inside the eave 12.
A gas passage 14 is provided which communicates with 0. In such a case, when the main burner 1 is ignited, the gas sent from the mixing pipe 2 to each gas nozzle hole 10 via the gas distribution chamber 3 will flow through the gas passage 14 as shown in FIG. It is ejected from the slit 13, ignited, and then the slit 1
The main burner 1 is ignited by the flame 3.

According to the operation of both burners 1, 7, both burners 1,
7 may boil over from a pot placed on top of the cap 11, but this dripping is blocked by the eaves 12 and is difficult to enter into the slit 13. By removing it from 10, it can be cleaned, and the flame hole 9 can always be maintained in a state with good flame transfer performance.

(Effects of the Invention) As described above, according to the present invention, since there is an eaves above the slit that spouts gas for ignition, it becomes difficult for boiling liquid etc. to enter the slit, and even if it does Even if the large capacity burner and the cap are separate, the cap can be removed to clean and remove the boiling liquid, and there is no member to prevent boiling liquid from entering the flame hole for ignition. Moreover, since the flame hole is integrated with the large-capacity burner, the flame transfer performance of the flame hole is improved compared to the conventional type, which is difficult to clean.
