Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a so-called two-port burner mounting structure.

[Prior Art] FIGS. 3 and 4 show a conventional example of a mounting structure for mounting a burner 1 having two burner heads 1A and 1B on a can body 2 having two burner ports 2A and 2B. Shown.

That is, the burner 1 inserts the burner heads 1A, 1B into the corresponding burner ports 2A, 2B of the can body 2 and, with the seal packings 3A, 3B intervening around the respective burner ports 2A, 2B, the front face thereof. Burner front plate 4 protruding to the side
Fixing tools (fixing bolts and nuts) 6 are fixedly attached to the burner mounting plate 5 on the can body 2 side from the four corners.

In addition, in the figure, 7 is a fan motor for blowing air to the burner 1, and 8 is a heat exchanger installed in the can body 2. Also,
9A and 9B are insertion holes of a fuel nozzle provided on the front surface of the burner 1 and concentric with the burner ports 2A and 2B.
Indicates a pair of left and right ignition electrode rod insertion holes provided above the nozzle holes 9A and 9B.

[Problems to be Solved by the Invention] However, in the above two-port burner, the burner heads 1A, 1
In order to position B at the burner ports 2A and 2B and press them in a well-balanced manner, the number of fixed parts such as packing and fixing bolts and the number of assembly steps are doubled as compared with the case of a normal single port burner. Therefore, it is pointed out that the cost and labor required for mounting increase.

The purpose of the present invention is to simplify the mounting structure of the two-port burner to the can body to reduce the cost and simplify the maintenance. Therefore, it is possible to reasonably reduce the number of fixtures required for mounting the burner. Providing a burner mounting structure devised for.

[Means for Solving the Problem] The present invention provides a mounting structure for mounting a burner having two burner heads to a can body having two burner ports.
Place a fixture to fix the burner front plate on the burner side to the burner mounting plate on the can side, and place it at the corner on one side of the burner front plate.
On the opposite side of the burner front plate, it is arranged at the intersection of the line connecting the corner portion and the center of the burner mouth.

[Operation] That is, when the mounting structure of the present invention is adopted, a fixing tool which has conventionally been required to be fixed to the burner mounting plate at four points at each corner of the burner front plate is replaced with two corners on one side of the burner mounting plate. It can be covered by a total of three stops, one on the opposite middle part. Moreover, if the fixtures are arranged in the above positional relationship, the tightening force of the fixtures fixed to the burner mounting plate will naturally act through the center of each burner port, and the seal packing of each burner port will be actuated. It is possible to realize a mounting state with good balance accuracy in which the compressive force is evenly applied to.

[Embodiment] An embodiment of the present invention will be illustrated and described below.

1 and 2 show an embodiment of the present invention in comparison with the conventional example shown in FIGS. 3 and 4.

Here, in the two-port burner 1, the burner heads 1A and 1B are connected to the corresponding burner ports 2A of the can 2, as in the conventional example.
2B, with the seal packings 3A, 3B intervening around the respective burner ports 2A, 2B, the burner front plate 4 projecting to the front side is fixed to the burner mounting plate 5 on the side of the can body 2 ( The fixing bolts and nuts 6 are fixedly attached.

However, the number of fixtures 6 to be fastened to the burner mounting plate 5 from the burner front plate 4 and the fastening positions are improved to the following three-point fastenings instead of the conventional four-point fastenings.

That is, one side 4 of the burner front plate 4 that sandwiches the burner ports 2A and 2B.
In a, the upper and lower corners are arranged at L and M positions, while on the opposite side 4b of the burner front plate 4, a line P connecting the L position and the center I of the upper burner port 2A and the M
It is arranged at an intermediate position N between the upper and lower burner ports 2A and 2B, which is at the intersection of a line Q connecting the position and the center II of the lower burner port 2B.

In this mounting structure, first of all, the fixtures 6 are fastened to the burner front plate 4 at upper and lower two places L and M on one side 4a, and then,
When the fixture 6 is fixed to one location N on the opposite side 4b, the upper and lower burner heads 1A and 1B of the burner 1 are connected to the upper and lower burner ports 2A and 2B of the can body 2 through the seal packings 3A and 3B, respectively.
In addition, it can be stably fixed by pressing the centers I and II from both sides. That is, in this structure, the two fixtures 6 and 6 arranged at the upper and lower corner portions L and M on one side of the burner front plate 4 and the one fixture 6 arranged at the intermediate position N on the opposite side 4b are provided. Together, they serve to hold the upper and lower burner heads 1A and 1B against the upper and lower burner ports 2A and 2B at the same time, and the fixture 6 at the intermediate position is, so to speak, one with two fixtures in common. Has become.

Therefore, if this mounting structure is adopted, the number of fixtures 6 required for mounting the two-port burner 1 on the can body 2 can be omitted, and the cost and labor required for mounting the burner can be reduced accordingly.

Further, in this three-point stop structure, the fastening force applied to the burner 1 from the three fixtures 6 arranged on both sides of the burner front plate 4 is the same as the lines P and Q connecting the fixtures 6 and 6 on both sides to each other. Since the centers I and II of the upper and lower burner ports 2A and 2B located just in the middle are applied, a uniform tightening force is applied to the respective burner ports 2A and 2B in the circumferential direction. That is, in the case of the conventional four-point stop, if the tightening force of the fixture fixed at each corner portion varies, the tightening margins of the seal packings 3A and 3B arranged on the burner ports 2A and 2B are partially tightened. Although it is easy to cause an unbalanced mounting state in which the upper and lower burner heads 1A and 1B are brought into close contact with each other evenly even if the fastening force of the fixture varies, the balance accuracy is improved. Can be installed well.

In addition, with this mounting structure, the size of fixed components such as the burner front plate 4 and the burner mounting plate 5 can be made more compact.

[Effects of the Invention] As described in detail above, the burner mounting structure of the present invention can reasonably reduce the number of fixtures required for mounting the two-port burner on the can body, which leads to cost reduction and simplification of maintenance. At the same time, the effect of improving the accuracy of mounting the burner head to each burner port can be obtained.
