Description

Metal fiber burner

The present invention relates to a metal fiber burner. More specifically, the present invention relates to a metal fiber burner, and more specifically, by installing a plurality of linear joints in the longitudinal direction that eject mixed gas to the ignition member of the burner device, and to prevent the sagging of the ignition member that ignites the flame through these linear joints. This is about a metal fiber burner that prevents

In general, combustion devices are installed in various spaces such as homes, offices, or other factories, and supply hot water and heating water through heat exchange with a heat source generated by burning mixed fuel of air and gas. Or it is a device that heats air.

For this purpose, the combustion device receives air and gas from the outside, mixes them, then receives the mixed fuel into the internal space from a fuel supplier that supplies the mixed fuel, and then burns the mixed fuel through an ignition device. By generating a flame, the air in the combustion device is heated by this flame, or the heating return water passing through the water pipe is heated.

Patent Document 1 shows a conventional fire tube boiler. Referring to this, a heat exchanger that has a hollow shape and allows heat exchange between the heat medium and combustion gas in the internal space is installed on the top of the heat exchanger, and the mixed gas is inside the heat exchanger. It consists of a mix chamber that guides the mixed gas to be discharged directly downward and ignites this mixed gas to create a flame in the combustion chamber of the heat exchanger.

At this time, the mix chamber covers the upper part of the heat exchanger, and is provided with a flat burner that passes the mixed gas inside and burns the mixed gas, and is bent to be located below the flat burner on one side to form a flat burner. It includes first and second ignition rods that generate sparks at the bottom.

Here, the ends of the first and second ignition rods are installed close to each other at a predetermined distance, so that a spark is generated between them, and the mixed gas discharged directly below the flat burner is ignited by this spark, creating a flame. It will happen.

However, in Patent Document 1 as described above, the flat burner that maintains the flame ignition state continues at a high temperature, and when used for a long time, sagging occurs in the flat burner, and the mixed gas is ejected due to sagging and deformation of the flat burner. It is not done evenly, so the mixed gas is ejected biased in one direction of the flat burner. As the mixed gas is ejected irregularly, abnormal combustion occurs and at the same time, a lifting phenomenon occurs due to ignition of the mixed gas ejected biased in one direction. As the separation distance between the flat burner and the correlative plate changes due to shape deformation caused by the flat burner sagging, the flame ignited from the flat burner reaches the correlative plate directly, causing the correlative plate to be added by the high temperature heat. It may cause shape deformation, and as a result, there is a problem in that combustion performance is reduced and the reliability of the product is reduced at the same time.

The spark plug 300 has an ignition gap (W1) at its tip that is relatively small compared to the separation distance (L1) between the linear joints 230, and generates a spark that is ejected between the linear joints 230. Ignite the mixed gas.

The spark plug 300 generates a spark at its tip, and this spark ignites the mixed gas ejected between the linear joints 230.

The metal fiber burner according to the present invention configured as described above is used as follows.

Hereinafter, description of the mixed gas supply unit (not shown) that guides the mixed gas to be supplied in the direction of the heat exchange housing 100 will be omitted.

First, a spark plug 300 is installed on one side of the heat exchange housing 100, so that the tip of the spark plug 300 is located within the heat exchange housing 100, and in that state, the heat exchange housing 100 is opened. Install the burner device 200 on the upper part.

At this time, the frame 210 of the burner device 200 is closely fixed to the upper edge of the heat exchange housing 100 so that the ignition member 220 is located within the heat exchange housing 100, thereby forming the heat exchange housing 100. ) is finished.

Here, a fixture 214 is installed on the bottom edge of the frame 210 of the burner device 200, and the insulating material 215 is fixed and installed within the fixture 214, so that the bottom edge of the frame 210 is formed with the insulator ( 215).

At this time, the fixture 214 forms a fitting groove 214a on the upper surface, and this fitting groove 214a is press-fitted and fixed to the protrusion 213 of the frame 210, so that the fixture 214 is attached to the frame. (210) It is maintained in close contact with the bottom edge.

In addition, the ignition member 220, which is a layered combination of the mesh network 222 and the knit 221, is inserted into the insertion groove 212 formed on the upper surface of the frame 210, and the ignition member 220 is inserted into the insertion groove 212. (212) By bringing it into close contact with the edge, the through hole 211 of the frame 210 is completed.

In particular, the linear joint portion 230, which is formed in plural numbers at a predetermined interval in the longitudinal direction on the ignition member 220 of the burner device 200, is embedded and installed in the ignition member 220 by welding, and the ignition member ( The mesh network 222 and the knit 221 of 220 are maintained in a laminated and coupled state, and the ignition member 220 is supported in the longitudinal direction.

And, as the burner device 200 is coupled to the upper part of the heat exchange housing 100, the fire transfer passage 231 between the linear joints 230 embedded in the ignition member 220 is formed through the spark plug 300. ) is located on the same vertical line as the tip.

At this time, directly above the ignition member 220 corresponding to the spark plug 300, there is a cover joint 240 that reduces the amount of mixed gas ejected in the direction of the spark plug 300 through the ignition member 220. ) is installed in landfill.

That is, the ignition gap W1 formed at the tip of the spark plug 300 is located on the same vertical line as the hole of the mesh network 222 formed in the space between the linear coupling portions 230.

Meanwhile, when the mixed gas is supplied to the upper part of the heat exchange housing 100 through the mixed gas supply unit (not shown) installed in the heat exchange housing 100 of the metal fiber burner combined as described above, this mixed gas is supplied to the burner device ( It is ejected into the inner space of the heat exchange housing 100 through the ignition member 220 of 200.

That is, as the mixed gas is supplied to the ignition member 220 inserted into the insertion groove 212 of the frame 210 and the mixed gas passes through the mesh network 222, this mixed gas becomes the It is evenly distributed by the mesh network 222 and is ejected in the direction of the knit, and then the mixed gas is ejected toward the inside of the heat exchange housing 100 through the nit 221 and the passage hole 211.

And, a spark is generated in the ignition gap W1 of the spark plug 300 located on the same vertical line (VL) as the fire transfer passage 231 of the linear joint 230 installed in the ignition member 220. When this occurs, the mixed gas ejected downward from the nit 221 is ignited by a spark generated in the ignition gap W1, causing a flame.

Here, the ignition gap W1 of the spark plug 300 is positioned on the same vertical line as the hole of the mesh network 222, so that the nit 221 ejected from the hole of the mesh network 222 is By igniting the mixed gas, ignition performance is relatively improved compared to locating the ignition gap (W1) directly below the linear joint 230.

At this time, the area of the fire transfer passage 231 formed between the linear joints 230 is relative to the area of the upper burner part 220a and the lower burner part 220b of the ignition member 220 through which the mixed gas is ejected. By being narrowly formed, the ejection speed of the mixed gas ejected from the fire transfer passage 231 is improved, and the flame is pre-ignited in the fire transfer passage 231.

And, the flame ignited in the fire transfer passage 231 is transferred toward the upper burner part 220a and the lower burner part 220b formed adjacent to each other based on the linear joint 230, and the upper burner part ( 220a) and the lower burner part 220b are ignited, and at the same time, the mixed gas passing through the linear joint 230 and ejected downward is ignited, so that the flame is evenly distributed over the entire area of the ignition member 220. It is ignited.

At this time, as the fire spreads to the upper burner unit 220a or the lower burner unit 220b, the flame of the upper burner unit 220a or the lower burner unit 220b flows through the fire transfer passage 231. As the fire spreads to the upper burner unit 220a or the lower burner unit 220b, the fire quickly progresses to the upper and lower burner units 220a and 220b.

In particular, the linear joints 230 formed at both ends of the linear joints 230 are formed at a predetermined distance from the rim of the ignition member 220, so that the mixed gas continues to flow from the rim of the ignition member 220. By being ejected, flame ignition occurs simultaneously along the edge of the ignition member 220.

Here, the ignition member 220 continuously ejects the mixed gas while allowing the flame to remain on the surface of the knit 221, so that the mixed gas is ignited by the flame, and accordingly, the ignition member 220 gradually It is heated.

In addition, the cover joint 240 embedded in the ignition member 220 is formed directly above the ignition plug 300, so that the amount of mixed gas ejected in the direction of the ignition plug 300 increases through the holes of the mesh network 222. By reducing the amount ejected to the nit 221 relatively, the spark plug 300 is prevented from sagging or deforming due to the heat of the flame.

At this time, the longitudinal direction of the ignition member 220 is supported by the linear joint 230, thereby preventing the ignition member 220, which maintains the heat of the flame, from sagging.

Thereafter, the flame ignited by the ignition member 220 heats the air within the heat exchange housing 100, and at this time, the air heated within the heat exchange housing 100 exchanges heat with the water pipe 101, By heating the water pipe 101, the circulating water passing through the water pipe 101 is changed into heating water or hot water.

In particular, the flame ignited below the ignition member 220 is dispersed in all directions, and at this time, the insulating material 215 installed on the fixture 214 on the bottom edge of the frame 210 covers the bottom edge of the frame 210. , the flame ignited by the ignition member 220 is blocked from reaching the inner wall of the heat exchange housing 100, thereby preventing thermal deformation from occurring on the inner wall of the heat exchange housing 100.

As described above, the linear joint 230 is embedded in the ignition member 220 of the burner device 200 to prevent sagging of the ignition member 220 heated to a high temperature by the linear joint 230.
