JPH0257807A - Flame transferring device for gas burner - Google Patents

Abstract

PURPOSE:To prevent any explosion type ignition by a method wherein one end of a flame transmitting fitting having a trapezoidal shape with its bottom part being opened is inserted into a recessed hole of one side surface of a burner fixing box and kept free, and then the other end of the flame transmitting fitting is inserted into a recessed hole at one side surface of the burner fixing box and fixed. CONSTITUTION:A flame transmitting fitting 11 is placed at one location of a portion 2b having no flame port 2a of a burner 2 while being crossed at a right angle with the burner 2. One end 11a of the flame transmitting fitting 11 is fitted to recessed holes 3a arranged at both side walls of the burner fixing box 3 and kept open. The other end 11b is fitted to a recessed hole 3a of the burner fixing box 3 and fastened with a screw. Further, the flame transmitting fitting 11 is formed into a trapezoidal shape with its bottom surface being released, placed over the portion 2b having no flame hole 2a between the flame holes 2a. Flame holes between the burners are interfered to each other along an inclined surface 11c of the flame transmitting fitting and then the flame is transmitted. With this arrangement, a superior combustion area can be obtained and then any explosion type ignition can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a device for transferring flame between burners during combustion in burners of gas combustion equipment.

In conventional gas water heaters, in order to obtain a wide range of water temperature control,
Combustion that can be achieved from high temperatures to temperatures close to water temperature is required, and strong combustion and weak combustion are also required from the initial stage of ignition.There are various combustion methods, and consideration must be given to single-point ignition and flame transfer.

Problem to be Solved by the Invention When using a gas water heater to obtain a low water temperature through weak combustion, if the amount of gas is small, the flame transfer between burners will be poor, and if the amount of gas is increased, it may easily cause an explosion and ignition. , good gas combustion settings were not obtained.

The present invention solves the above-mentioned conventional techniques by ensuring the spotting holes during weak combustion and ensuring flame transfer between burners.

Means for Solving the Problems In order to solve the above problems, the present invention provides a Bunsen burner having a flame hole portion divided into several sets of flame holes and arranged at regular intervals, and the Bunsen burner. Several burner irons are lined up in parallel and fixedly held around the outer periphery, intersecting the Bunsen burners at right angles and lying on the flame hole portion of each Bunsen burner without a flame hole, with the bottom surface facing up. The tank is made up of a gutter-like fire transfer metal fitting bent into an open trapezoidal shape, one end of the fire transfer metal fitting is inserted into a notch hole on one side of the burner iron, and the other side of the fire transfer metal fitting is opened. The end was inserted into the notch hole on one side of the burner iron and fixed, which is a fire transfer device for the burner iron.

Function The present invention uses the above-mentioned flame transfer device to ensure flame transfer between burners, reduce flame interference between burners and between flame holes, eliminate incomplete combustion parts, and obtain a stable and good combustion area. can be

EXAMPLE An example of the present invention is shown in FIGS. 1, 2, 3, and 4.
This will be explained based on FIG.

The water heater body 1 includes a burner cage 3 surrounding several burners 2 arranged in parallel, a heat exchanger 4, a fan 5 for forcibly discharging exhaust gas, an exhaust duct 6, a nozzle 7, and a gas pipe 8.
, a water supply pipe 9, and a hot water supply pipe 10.

As shown in FIG. 2, the flame transfer fitting 11 is placed at one location on a portion 2b of the burner 2 where there is no flame hole 2a, intersecting the burner 2 at right angles. Further, one end 1 of the fire transfer fitting 11 is inserted into the notch hole 3a provided on both side walls of the burner iron 3.
1a is fitted into an open state, and the other end 11b is fitted into a notch hole 3a of the burner iron 3 and fixed with a screw.

Further, the fire transfer fitting 11 is formed in a trapezoidal shape with an open bottom, and is placed on a portion 2b between the flame holes 2a and without the flame hole 2m, so that the flame holes interfere with each other along the slope 11c, and at the same time, the burner The flame between the flame holes and the inclined surface 11 of the flame transfer fitting
Interference and fire transfer along c. The fire transfer fitting 11 is the flame hole 2
The installation does not block the flame hole or cover the area directly above the flame hole, and does not affect the flow of secondary air, resulting in stable and good combustion.

Effects of the Invention As described above, the present invention ensures fire transfer by using a trapezoidal-shaped flame transfer metal with an open bottom side, which is placed on the flame hole portion of each Bunsen burner installed side by side, and which has no flame holes. A stable and good combustion range can be obtained, use can be started with weak combustion, and explosive ignition can be eliminated.
