Description

Metal fiber burner

The present invention relates to a metal fiber burner, and more specifically, to form a large diameter through hole on the bottom surface of the insertion groove of the frame and a plurality of small diameter through holes along the edge of the large diameter through hole. It relates to a metal fiber burner that increases the amount of mixed gas ejected from the bottom of the ignition member by simultaneously passing mixed gas through the diameter passage hole.

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

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 burner housing having a recessed receiving portion formed on the upper surface and an opening formed on the bottom surface of the receiving portion, and a burner housing jointly installed on the upper surface of the edge of the open portion of the burner housing. , a metal fiber that ejects the mixed gas and induces the flame to stay on the surface is installed in close contact with the upper surface of the metal fiber, and its edge is installed in close contact with the bottom of the receiving section to disperse and eject the mixed gas in the direction of the metal fiber. It consists of a slit plate.

Here, when the mixed gas is supplied toward the receiving portion of the burner housing, the mixed gas passes through a plurality of slit grooves formed on the slit plate within the receiving portion and is evenly dispersed and ejected in the direction of the metal fiber.

Then, as the mixed gas supplied to the metal fiber is ejected downward through the metal fiber, it is ignited by a spark generated from the spark plug, creating a flame.

At this time, the metal fiber continuously ejects the mixed gas and allows the ignited flame to remain on the surface, thereby maintaining the flame ignition on the surface of the metal fiber.

However, in Patent Document 1 as described above, the area of the open part is formed relatively small compared to the area of the slit plate and the metal fiber, so the amount of mixed gas passing through the open part is reduced, and the ignition at the bottom of the metal fiber is proportional to the amount of mixed gas passing. Flame distribution is reduced, combustion performance is reduced, and there is the inconvenience of having to increase the area of the opening to increase the amount of mixed gas passing. At the same time as the area of the opening increases, the bonding of the slit plate and metal fiber to the bottom of the receiving part is required. The area is rapidly reduced, and due to this reduction in the joint area, the bonding strength between the slit plate and metal fiber and the bottom surface of the receiving part is significantly reduced. At this time, the high temperature heat ignited from the metal fiber is transferred to the joint, and the slit plate and metal There is a problem in that the fiber is easily separated from the bottom of the receiving part, and as a result, the product's functionality is lost and the reliability of the product is reduced.
