Description

Portable catalytic combustion burner {PORTABLE CATALYSIS BURNER}

The present invention relates to a catalytic combustion burner, and more particularly, is installed in a solid fuel or a gas burner when camping outdoors to generate heat with an flameless heat using a gas generated from a solid fuel or a gas supplied from a gas burner. A portable catalytic combustion burner for maintaining the temperature of water or making it available for heating.

Catalytic combustion technology, which has recently attracted much attention as a new combustion technology, uses a catalyst (also called a combustion catalyst) to combust combustible gas such as city gas or LPG at a temperature much lower than a flame combustion reaction.

In catalytic combustion, since the combustion reaction occurs on the catalyst, the activation energy is lowered, so that the combustion reaction is stably performed even at low temperatures, the emission of pollutants such as nitrogen oxides is low, and the generated heat is released in the form of far-infrared radiation energy. It is known as a combustion method that can efficiently utilize the energy generated in the process using heat.

Catalytic combustion technology is currently used in various fields such as VOC incineration, automobile exhaust gas treatment, and drying equipment, and the composition of the catalytic combustion device varies depending on the application method.

Catalytic combustion burners, which are used in industrial drying equipments, have recently been made in various forms due to their excellent heat transfer characteristics, and are classified into a diffusion combustion method and a premixed combustion method according to a fuel and air supply method.

As an example of such a catalytic combustion burner, a catalytic combustion burner using hydrogen as a fuel is disclosed in Korean Patent Publication No. 10-0522435.

As shown in FIG. 1 and FIG. 2, the catalytic combustion burner 10 that uses hydrogen as a fuel includes a main body 11, a hydrogen gas supply pipe 12, a distributor 13, a catalyst body 15, and a mesh 16. , The gas diffuser 17.

The main body 11 has a support portion 11a on which a support (200 in FIG. 5) for supporting a heating object (not shown) is seated. The lower part of the main body 11 is provided with a supply pipe 12 for supplying hydrogen gas into the main body. One end of the supply pipe 12 is connected to a hydrogen supply source to be described later, and the other side of the supply pipe is configured to protrude slightly upward from the lower surface of the main body 11.

The material of the main body, the supply pipe, the distributor, and the like can be sufficiently endured at high temperature by using stainless steel.

A distributor 13 is installed at the top of the supply pipe 12 to uniformly distribute hydrogen gas over the entire area of the burner. In the present embodiment, the distributor 13 forms a space X in which hydrogen gas is temporarily stored therein by coupling the upper member 13a and the lower member 13b to each other. The central portion of the upper member 13a is composed of a circular flat portion A so as to cover the upper portion of the supply pipe 12, and its outer circumferential surface is formed of an inclined surface B having a predetermined angle. On the inclined surface B of the upper member 13a, a plurality of nozzles C are formed uniformly so that hydrogen gas in the storage space X is supplied upwardly. In addition, one side of the lower member (13b) is sealably connected to the outer peripheral surface of the supply pipe 12, the other side of the lower member (13b) is sealably coupled to the end of the upper member (13a). The outer circumferential surface of the lower member 13b extends at the same angle as the inclined surface of the upper member 13a, in which the upper member 13a and the lower member 13b extend in parallel at a predetermined interval.

The porous gas diffuser 17 is installed at the top of the distributor 13 to uniformly diffuse the hydrogen gas from the nozzle hole C upwards. The gas diffuser 17 may function as a heat insulator that blocks heat between the catalyst body 15 and the gas supply pipe 12.

The catalyst body 15 is installed above the gas diffuser 17. The catalyst body 15 is a reactor in which hydrogen gas supplied from the supply pipe 12 reacts with oxygen in external air to generate heat.

However, such a catalytic combustion burner has to use hydrogen, and its use is limited, and it is impossible to carry and use it outdoors such as camping.

First, as shown in FIG. 6, when the solid fuel C is used, the solid fuel C is lit while the handle 171 of the end cover 170 is unfolded and held by the hand, and then the case 110. Is spaced a certain distance from the solid fuel (C) to directly heat the third catalyst metal foam 150 to the fire for 5 to 10 seconds.

Then, the case 110 is mounted on the solid fuel C and fixed by the end cover 170.

Then, while the solid fuel C is sealed by the end cover 170, the fire is turned off, and the vaporization gas is raised.

When the vaporized gas rises, as shown in FIG. 8, the gaseous gas passes through the heated third catalyst metal foam 150 and contacts with the air introduced through the first catalyst metal foam 120 to cause a catalytic reaction. Heat of about 250 to 300 ° C is generated, and the vaporized gas is diffused in the space between the second catalyst metal foam 130 by the second space keeping catalyst metal foam 160. At this time, the heat generated from the third catalyst metal foam 150 is radiated to the lower solid fuel (C) side and the solid fuel melts into a liquid state and vaporizes, thereby continuously generating vaporized gas.

The heat of about 500 ~ 600 ℃ is generated while causing a catalytic reaction in contact with the air introduced through.

Thus, the generated heat of 500 ~ 600 ℃ is discharged to the upper portion of the case (110).

In addition, as shown in FIG. 7, when the gas burner D is to be used, the handle 171 of the end cover 170 is extended, and then the case 110 is placed on the gas burner D, and the gas burner D ), The third catalyst metal foam 150 is directly heated by fire for 5 to 10 seconds. At this time, the end cover 170 is directed downward.

Then, the fire of the gas burner (D) is turned off and the gas rises when the gas is leaked in a certain amount.

When the gas is raised, the gas passes through the heated third catalyst metal foam 150 as shown in FIG. 8 and contacts the air introduced through the first catalyst metal foam 120 to cause a catalytic reaction. Heat of ˜300 ° C. is generated, and the gas is diffused in the space between the second catalyst metal foam 130 by the second space keeping catalyst metal foam 160.

In addition, the gas diffused by being heated in the space between the second catalyst metal foam 130 and the third catalyst metal foam 150 passes through the second catalyst metal foam 130 and passes through the first catalyst metal foam 120. While in contact with the air introduced through the catalytic reaction generates heat of about 500 ~ 600 ℃.

Thus, the generated heat of 500 ~ 600 ℃ is discharged to the upper portion of the case (110).

Therefore, according to the present invention portable catalytic combustion burner, it is easy to carry and convenient to use, and it is installed in a solid fuel or gas burner when camping outdoors, and catalytic reaction using gas generated from the solid fuel or gas supplied from the gas burner By generating heat with no flame to maintain the temperature of the heated water or can be used for heating can prevent fire.
