The present invention relates to a structure for installing the salt joint support guide of a gas combustion burner, and more particularly, when installing the salt joint composed of a plurality of salt hole plates on the burner body, the salt joint support guide is installed at the left and right sides of the salt joint. The present invention relates to a structure for supporting the salt hole support guide of a gas combustion burner which minimizes the deformation of the salt hole plate which may occur during combustion and prevents the leakage of the mixer by minimizing the gap that may occur on the combustion surface when installing the salt hole.

As is well known, a gas burner that burns gas fuel is supplied with primary, primary, or secondary air for combustion according to a method of mixing gas fuel and combustion air, and completely mixed with fuel in the first stage. In the latter type of burner, in the case of the premixed gas burner, the combustion method is to mix the gas and air at the mixing ratio of the combustion optimum state and then supply it to the salt hole surface for combustion.

As described above, in the premixed gas burner used in a combustion device such as a gas boiler or a hot water heater for premixed combustion, the salt flat surface leading to the salt hole where sparks are formed is a ceramic plate, a heat resistant stainless steel plate, a metal fiber mat, or the like. I'm using.

That is, in the conventional premixed gas combustion burner, the salt hole of the form in which the salt hole is processed in one plate or cylinder is used, or the salt hole of metal fiber or ceramic plate manufactured by the method of weaving or sintering is used.

However, in the case of the salt hole arranged in the single plate or cylinder, there is a possibility of deformation of the burner combustion surface due to thermal stress, and in severe cases, there is a problem that the salt hole is damaged, causing incomplete combustion and backfire. there was.

In addition, since the ceramic plate and the heat-resistant stainless plate have a certain rigidity in structure, there is no difficulty in assembling with the rectifying plate in the burner, but in particular, when the ceramic plate is used as the salt material by the sintering method, When the condensate generated in the heat exchanger falls on the combustion surface, the surface of the salt hole is damaged by water, resulting in an uneven flame hole, which may cause incomplete combustion.

In addition, even when the metal fiber mat manufactured by the weaving method is used as the salt hole, the worker must pull and assemble the metal fiber when assembling the burner, so that a large or small salt hole is formed on the metal fiber mat, resulting in uneven flame. There was a risk of incomplete combustion and possible backfire.

In particular, the metal fiber mat is made of a metal fiber in a woven form, and has a flexible property.

Therefore, the metal fiber mat relies on welding or the like on the edge surface assembled with the rectifying plate in the burner in order to maintain the airtight so that the mixed gas in the burner can burn only on the surface of the metal fiber mat. .

In other words, since the flexible metal fiber mat is placed on the mat support guide in the burner and assembled depending on welding, the machining process is complicated and the processing precision is also lowered, and the metal fiber mat is flexible and the deflection occurs.

Further, as described above, a gas combustion burner using a salt ball processing a salt hole in one conventional plate or a gas combustion burner used as a salt hole by forming a cylindrical shape of the plate processed by the salt hole into a cylindrical hole has a salt hole when the burner is operated. The thermal stress acts on the surface of the burner, causing deformation such as distortion on the burner surface of the burner due to thermal expansion.

 In particular, since the salt hole is fixed to the burner, there is a fear that the degree of warpage becomes more severe because there is no space for absorbing expansion.

In addition, when the warpage deformation of the flame hole occurs, a specific part is overheated even during normal combustion, causing burnout such as bursting of the salt hole, or a nonuniformity in flame shape due to uneven flow rate of the mixer due to the change of the salt hole cross-sectional area due to the deformation. And deterioration in combustibility may occur.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to abnormally burn by installing a salt hole support guide on the left and right sides of the salt hole when installing a salt hole composed of a plurality of salt hole plates on the burner body. It is to provide a salt flame support guide installation structure of the gas combustion burner which minimizes the salt plate deformation that may occur during the installation and minimizes the gap that may occur on the combustion surface when installing the salt spray.

The present invention for achieving the above object, the burner body is equipped with a blower for supplying the combustion air in the lower portion, while the salt hole is formed on the combustion surface of the burner body a plurality of salt holes formed at a predetermined interval In the gas combustion burner having a burner portion disposed to be burned when the gas and air are supplied in a mixed state, the salt hole is composed of a plurality of salt hole plate is seated and supported by the locking step formed on the combustion surface of the burner body It is achieved by providing a salt hole support guide installation structure of the gas combustion burner, characterized in that the salt hole support guide is installed on the left and right sides of the salt hole.

At this time, it is preferable to leave a sufficient separation distance between the left and right sides of the salt hole, the salt hole support guide is installed to ensure a space for absorbing the expansion amount when the salt hole is thermally expanded left and right.

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In particular, an orifice 180 is provided between the solenoid valve 160 and the gas nozzle 170 installed in the manifold 140 to control the gas flow rate. Accordingly, when calorie change (LNG↔LPG) is required, the calorie change is possible by replacing only the orifice 180 without replacing the gas nozzle 170.

At this time, between the solenoid valve 160 and the orifice 180, the valve O ring 162 and the valve seat packing 163 are mediated.

As such, in the present invention, a manifold 140 is provided to supply air and gas through a separate flow path in the gas combustion burner, and the manifold 140 has a gas nozzle 170 which serves to distribute gas for combustion. ) Is only installed.
