うにした。 The support plate 11 is provided with air ports 11a and 11b for dividing the combustion air supplied by the fan 16 into primary air and secondary air. The guide member 6 is fixed to the lower surface of the support plate 11 with screws 17, and the guide member 6 is a metal plate having a U-shaped cross section and having through holes 18 facing each mixing pipe inlet 3a. 6a and a metal plate 6b having a through hole 19 corresponding to the through hole 18, and an insertion groove 6c for inserting the damper member 5 thereinto.
The insertion groove 6c is communicated with the first through hole 7, and the damper member 5 is inserted into the insertion groove 6 through the first through hole 7.
It was designed to be removably attached to C. In the illustrated example, both the through holes 7 and 13 are formed into one common hole.
In the illustrated example, the through hole 18 provided in the metal plate 6a is configured to have a relatively large diameter to regulate the primary air for high-calorie gas, and the guide member 6 itself has a damper function. The damper member 5, which is removably installed in the damper member 6, is constructed by drilling through holes 20 of relatively small diameter in a metal band plate to reduce the amount of air in proportion to the amount of primary air for low-calorie gas.
For example, when switching the fuel from high calorie gas to low calorie gas, the damper member 5 equipped with low calorie air holes is inserted into the guide member 6.

で小さくなり透孔20が最も小さい。 In the above embodiment, the through hole 18 provided in the metal plate 6a constituting the guide member 6 was used to regulate the amount of air corresponding to the high calorie gas.
For example, a damper member equipped with a through hole for primary air regulation that corresponds to high calorie gas and a damper member equipped with a through hole for primary air regulation that corresponds to low calorie gas without having the function of the guide member 6. It is also possible to prepare each of them, select one appropriately, and insert it into the guide member 6 for use. The diameters of the through holes 11a, 18, 19, and 20 are the same as those of the through holes 11a.
is the largest, followed by the through hole 19, then the through hole 18, and the through hole 20 is the smallest.

すれば良い。 Now change the gas type from low calorie gas such as 6C to 13C.
To replace the gas nozzle 4 and damper member 5 with high-calorie gas such as
After removing the screw tightening the nozzle holder 12 and the damper member 5, and replacing the nozzle 4 with a high-calorie one, insert the nozzle holder 12 and fix the flange part 14 again with screws, etc. Just do it.

簡単にガス種交換に対応出来る。 In this case, the primary air amount corresponding to the high calorie gas is supplied through the through hole 18 formed in the guide member 6, and conversely, in order to convert the gas type from high calorie gas to low calorie gas, All you have to do is loosen the screws tightening the flange part 14 and replace the gas nozzle 4 of the nozzle holder 12 with the nozzle 4 for low calorie gas, and at the same time insert the damper member 5 for low calorie gas into the guide member 6. Gas types can be easily exchanged by simply unfastening the flange portion 14 with screws and replacing the damper member 5 and the gas nozzle 4 provided with the nozzle holder 12 through the through holes 7 and 13.

に解消出来るの効果がある。(Effect of the invention) As described above, according to the invention, a guide member that supports the damper member in a freely sliding and retractable manner is provided between the mixing pipe inlet and the gas nozzle, and the gas nozzle is attached to one side wall surface of the combustion barrel. A first through hole is provided to support the damper member so that it can be inserted and removed freely, and a second through hole is provided in close proximity to the first through hole for allowing the damper member to be inserted into and removed from the guide member from outside the combustion barrel. Therefore, when replacing the damper member due to gas type change, the replacement work can be carried out without having to do troublesome work such as disassembling the combustion cylinder as in the conventional case. Since the holes are closed with flanges provided at the ends of the gas nozzle holder, both through holes can be easily closed, and the problem of air flowing out from both through holes can be easily solved.
