Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface combustion burner device.

[0002]

2. Description of the Related Art As shown in FIG. 1, a conventional surface combustion burner is provided with a mat such as a metal fiber on a flame generating surface of a metal casing, and the mat is supported by a flange provided on an inner peripheral edge of the casing. Configuration.

[0003]

This type of burner is widely used, for example, in the food processing field, various drying fields, and the like. Therefore, it is desirable that the burner can be used in an upward, downward, or horizontal direction depending on the application. However, when the conventional burner is used in such a direction, as shown in FIGS. 2 to 4, even when used in an upward direction, the flange portion is deformed by radiant heat. The flange is directly heated by the flame, and the flange is red-heated and deformed. The deformed portion loses the sealing property and causes gas leakage or flashback.

[0004]

In order to solve the above-mentioned problems, the present invention is to provide a mat made of a metal fiber or the like on the flame generating side of a ceramic casing, and to interpose a packing between the mat and the casing side wall. A fool hole is provided through the mat, the packing and the casing side wall, and a bolt is inserted into the fool hole to integrate the three members.

[0005]

[Function] A mat such as a metal fiber forms a flame by itself, and expands and contracts thermally. However, the expansion and contraction due to the heat is absorbed by an idiot, and the sealing property is impaired without deformation. Never.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a ceramic casing, on which a mat 2 of metal fiber or the like is provided on the flame generating side of the casing 1. A packing 4 is interposed between the mat 2 and the casing side wall 3, and a fool hole 5 is provided through the mat 2, the packing 4 and the casing side wall 3, and a bolt 8 is tightened through the fool hole 5. Then, the three are integrated. Reference numeral 6 denotes a current plate.

[0007] The premixed gas is introduced into the casing 1 from the premixed gas introduction section 7 and is rectified by the rectifying plate 6 to reach the mat 2, where a subdivided flame is formed. The mat 2 expands and contracts due to a temperature difference with the casing side wall 3, but since the expansion and contraction is absorbed by the fool holes 5 through the packing 4, there is no deformation of the mat 2 itself. Therefore, the sealing performance is maintained, and it is possible to prevent a flashback or a mixture leak. As a result of the operation, no mat deformation or the like occurred at all even when used continuously for 100 hours in a downward state.

As described above, according to the present invention, since the configuration of the surface combustion burner itself is not deformed, there is no danger of leakage of the premixed gas and backfire, and any use state such as upward, downward and sideways can be performed. There is an excellent effect that can be.
