Description

Description
A GAS BURNER FLAME GENERATOR
Technical Field
[1] The present invention relates to a combustion system for a gas burner, and more particularly, to a combustion system for a gas burner capable of achieving high thermal power combustion and increasing combustion efficiency. Background Art
[2] Typically, a number of supports for supporting a heating container are provided on a gas burner, and a cylindrical combustion system is mounted inside the gas burner for mixing a combustible gas from a gas can with oxygen to burn the combustible gas. The combustion system includes a number of nozzles formed on a side thereof for injecting the combustible gas. The combustible gas injected from the nozzles is burned outside the combustion system to heat a bottom of the heating container.
[3] In this structure, since combustion occurs outside the combustion system, combusti on-induced flame is created outward the bottom of the heating container, thereby greatly degrading thermal efficiency and unnecessarily increasing a cooking period of time.
[4] As the combustion occurs outside the combustion system, the flame fluctuates in a weak wind condition, thereby further degrading thermal efficiency. In some cases, fire is extinguished by wind. This causes leakage of the combustible gas, thus wasting fuel and running a risk of explosion. Disclosure of Invention Technical Problem
[5] An object of the present invention is to provide a combustion system for a gas burner capable of achieving high thermal power combustion, increasing thermal efficiency to conserve fuel, and shortening a cooking period of time by inducing flame into a heating container.
[6] Another object of the present invention is to provide a combustion system for a gas burner capable of preventing leakage of a combustible gas and eliminating a risk of explosion by preventing fire being extinguished by wind. Technical Solution
[7] One aspect of the present invention provides a combustion system for a gas burner comprising:
[8] a guider body 10 fixed to a predetermined portion of the gas burner and being generally in a cylindrical shape, the guider body 10 having a gas pipeline 15 slantingly formed at an edge of the guider body 10 for supplying a combustible gas and oxygen, and a body hole 10c formed downwardly; a vortex-forming wing member 20 provided inside and spaced apart from the guider body 10 and formed at the circumference of the body hole 10c, the vortex-forming wing member 20 having a number of oblique wings 21 disposed in a cylindrical shape; a vortex-forming mesh 30 provided inside the vortex-forming wing member 20, the vortex-forming mesh 30 being generally in a cylindrical shape and having a number of vortex-forming holes 31 ; an annular vortex- forming member 40 provided on the upper part of vortex-forming wing member 20, the annular vortex-forming member 40 being generally in an annular shape and having a number of vortex-forming holes 41; and a perforated member 50 located on the upper part of guider body 10 for uniformly projecting a flame that is created upon combustion.
[9] The guider body 10 may comprise a number of heat-radiating pins 11 formed on a side thereof.
[10] Each passage 21a may be formed between the oblique wings 21 and faces a direction in which a vortical mixture gas flows, so that the vortical mixture gas flows into the passages 21a.
[11] The vortex-forming holes 41 may be implemented by forming a number of blanked faces 41a in a "D"-figured shape so that one side of the upper surface of the annular vortex-forming portion 40 is opened.
[12] The perforated member 50 may be made of a metal with strong corrosion resistance, and when high surface radiant heat is necessary, the perforated member 50 may be made of a porous metal fiber.
[13] A bottom of the vortex-forming wing member 20 may form a step with bottoms of the passages 20a, resulting in an elongated passage together with inner walls of the lower guide body 10a.
[14] Another aspect of the present invention provides a combustion system for a gas burner comprising:
[15] a guider body 110 fixed to a predetermined portion of the gas burner and being generally in a cylindrical shape, the guider body having a gas pipeline 115 slantingly formed at an edge of the guider body 110 for supplying a combustible gas and oxygen, and a body hole 110c formed downwardly; a vortex-forming guider 120 provided inside and spaced apart from the guider body 110 and formed at the circumference of the body hole 110c, the vortex-forming guider 120 having a number of guide pins 121 disposed in a cylindrical shape; a combustion drum provided inside the vortex-forming guider 120, the combustion drum 130 being generally in a cylindrical shape and having a number of nozzle holes 131; a combustion plate 140 provided on the upper part of combustion drum 130, the combustion plate 140 being generally in an annular shape and having a number of first vortex-forming holes 141 formed on an upper inward side of the combustion plate and a number of second vortex-forming 142 holes formed on an upper outward side of the combustion plate 140; a metal fiber 150 provided inside the combustion drum 130 having the nozzle holes 131, a combustible gas passing through the metal fiber 150; and a spark plug 160 for generating a spark inside the combustion drum 130.

[24] FIG. 1 is an exploded perspective view illustrating a combustion system for a gas burner according to a first embodiment of the present invention, FIG. 2 is a side cross- sectional view illustrating the combustion system of FIG. 1, FIG. 3 is a perspective view illustrating a guider body of FIG. 1, and FIG. 4 is a perspective view illustrating an annular vortex-forming member of FIG. 1.
[25] Referring to FIGS 1 to 4, the combustion system for a gas burner according to a first embodiment of the present invention comprises a guider body 10 fixed to a predetermined portion of the gas burner and being generally in a cylindrical shape, the guider body 10 having a gas pipeline 15 formed at an edge of the guider body 10 for supplying a combustible gas and oxygen, and a body hole 10c formed downwardly;
[26] a vortex-forming wing member 20 provided inside and spaced apart from the guider body 10 and formed at the circumference of the body hole 10c, the vortex-forming wing member 20 having a number of oblique wings 21 disposed in a cylindrical shape; [27] a vortex-forming mesh 30 provided inside the vortex-forming wing member 20, the vortex-forming mesh 30 being generally in a cylindrical shape and having a number of vortex-forming holes 31 ;
[28] an annular vortex-forming member 40 provided on the upper part of vortex-forming wing member 20, the annular vortex-forming member 40 being generally in an annular shape and having a number of vortex-forming holes 41; and
[29] a perforated member 50 located on the upper part of guider body 10 for uniformly projecting a flame that is created upon combustion.
[30] Preferably, the guider body 10 includes a lower guider body 10a fixed to a predetermined portion of the gas burner, and an upper guider body 10b coupled to the lower guider body 10a.
[31] The guider body 10 has a number of heat-radiating pins 11 formed on a side thereof. The heat-radiating pins 11 are for preventing heat generated by the inventive combustion system from being overly transferred to the gas burner.
[32] The gas pipeline 15 is slantingly formed at a side of the guider body 10. Accordingly, the combustible gas and the oxygen supplied through the gas pipeline 15 are converted to a first vortical mixture gas as they circulate along the outside of the vortex-forming wing member 20 inside the guider body 10. An inlet cover 16 is provided to an inlet 15a of the gas pipeline 15. The inlet cover 16 has a hole 16a through which the combustible gas is supplied, and holes 16b which are distinct from the hole 16a and through which external oxygen is supplied.
[33] As shown in FIGS. 1 and 3, a number of oblique wings 21 of the vortex-forming wing member 20 are formed overlapping each other in part and at certain intervals in a cylindrical shape, with passages 21a formed between the oblique wings 21. The passages 21a formed between the oblique wings 21 face a direction in which the first vortical mixture gas flows, so that the first vortical mixture gas flows into the vortex- forming wing member 20. A bottom of the vortex-forming wing member 20 forms a step with bottoms of the passages 21a, resulting in an elongated passage together with inner walls of the lower guide body 10a.
[34] The vortex-forming holes 31 of the vortex-forming mesh 30 mix the first vortical mixture gas flowing through the passages 21a of the vortex-forming wing member 20 with new oxygen flowing through the body hole 10c to create a second vortical mixture gas. The elongated passage formed at the bottom of the vortex-forming wing member 20 induces strong vortical combustion, and brings a great amount of induced air into the body hole 10c when a high-temperature flame is supplied upwardly, resulting in an optimal combustion condition. In this case, the high-temperature flame creates a radiant heat on the surface of the vortex-forming mesh 30. The radiant heat is supplied upwardly. The vortex-forming mesh 30 is disposed at the lower ends of the vortex-forming wing member 20 and the passages 21a, and serves as an obstacle to the passages to adjust a ratio of the mixture gas flowing into the annular vortex-forming member 40 and the vortex-forming wing member 20.
[35] Through a number of vortex-forming holes 41 of the annular vortex-forming member 40, the first vortical mixture gas created outside the vortex-forming wing member 20 is rapidly injected, thus creating a third vortical mixture gas with a high mixture ratio. The vortex-forming holes 41 are implemented by forming a number of blanked faces 41a in a "D"-figured shape so that one side of the upper surface of the annular vortex-forming member 40 is opened, as shown in FIG. 4. Preferably, all the vortex-forming holes 41 are formed in one direction.
[36] The perforated member 50 includes a number of flame projecting holes 51 that are formed uniformly so that the flame created by the combustion occurring inside the guider body 10 is projected evenly.
[37] The perforated member 50 is made of a metal with strong corrosion resistance.
When high surface radiant heat is necessary, the perforated member 50 may be made of, for example, a porous metal fiber to maximize performance of the perforated member 50.
[38] In the structure, the combustible gas and the oxygen from the gas pipeline 15 are converted into the first vortical mixture gas as they circulate inside the guider body 10. The first vortical mixture gas passes through the passages 21a of the vortex-forming wing member 20. As the first vortical mixture gas is then mixed with the external oxygen from the vortex-forming holes 31 of the vortex-forming mesh 30, the first vortical mixture gas is converted to the second vortical mixture gas. The first vortical mixture gas is also converted to the third vortical mixture gas as it rapidly passes through the vortex-forming holes 41 of the annular vortex-forming member 40. The second and third vortical mixture gases are burned at the upper portion inside the guider body 10 to create the flame. The flame is projected only upwardly through the flame projecting holes 51 of the perforated member 50 to heat the bottom of the heating container located on the upper part of combustion system, thus increasing thermal efficiency. Even when wind blows, the fire is not extinguished since the combustion is conducted inside the guider body 10.
[39] Hereinafter, a combustion system for a burner according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[40] FIG. 5 is an exploded perspective view illustrating a combustion system for a gas burner according to a second embodiment of the present invention, FIG. 6 is a side cross-sectional view illustrating the combustion system of FIG. 5, and FIG. 7 is a perspective view illustrating a combustion plate of FIG. 5. [41] Referring to FIGS. 5, 6 and 7, the combustion system for a gas burner according to a second embodiment of the present invention comprises a guider body 110 fixed to a predetermined portion of the gas burner and being generally in a cylindrical shape, the guider body 110 having a gas pipeline 115 slantingly formed at an edge of the guider body 10 for supplying a combustible gas and oxygen, and a body hole 110c formed downwardly; a vortex-forming guider 120 provided inside and spaced apart from the guider body 110 and formed at the circumference of the body hole 110c, the vortex- forming guider 120 having a number of guide pins 121 disposed in a cylindrical shape; a combustion drum 130 provided inside the vortex-forming guider 120, the combustion drum 130 being generally in a cylindrical shape and having a number of nozzle holes 131; a combustion plate 140 provided on the upper part of combustion drum 130, the combustion plate 140 being generally in an annular shape and having a number of first vortex-forming holes 141 formed on an upper inward side of the combustion plate 140 and a number of second vortex-forming holes 142 formed on an upper outward side of the combustion plate 140; a metal fiber 150 provided inside the combustion drum 130 having the nozzle holes 131, a combustible gas passing through the metal fiber 150; and a spark plug 160 for generating a spark inside the combustion drum 130.
[42] The guider body 110 includes a lower guider body 110a fixed to a predetermined portion of the gas burner, and an upper guider body 110b coupled to the lower guider body 110a. A number of heat-radiating pins 111 are formed on sides of the lower guider body 110a and the upper guider body 110b. The heat-radiating pins 111 are for preventing heat generated by the inventive combustion system from being overly transferred to the gas burner.
[43] The gas pipeline 115 is slantingly formed at a side of the guider body 110. An inlet cover 116 is provided to an inlet 115a of the gas pipeline 115. The inlet cover 116 has a hole 116a through which the combustible gas is supplied, and holes 116b which are distinct from the hole 116a and through which external oxygen is supplied. The combustible gas and the oxygen supplied through the inlet cover 116 circulate along the outside of the vortex-forming guider 120 via the gas pipeline 115. In this process, the combustible gas and the oxygen are mixed evenly and become a first vortical mixture gas.
[44] As shown in FIG. 5(referring to FIG. 3), the guide pins 121 of the vortex-forming guider 120 are formed overlapping each other in part and at certain intervals in a cylindrical shape, with passages 121a formed between the guide pins 121. The passages 121a face a direction in which the first vortical mixture gas flows, so that the first vortical mixture gas flows into the vortex-forming guider 120.
[45] Combustion is conducted inside and over the combustion drum 130. The first vortical mixture gas passing through the passages 121a of the guide pins 121 flows into the combustion drum 130 passing through the nozzle holes 131 of the combustion drum 130, and becomes a second vortical mixture gas as it is mixed with new oxygen through the body hole 110c.
[46] The combustion plate 140 is generally in an annular shape. The combustion plate
140 includes an inner plate 140a having the first vortex-forming holes 141 and an outer plate 140b having the second vortex-forming holes 142. The inner plate 140a is slanted 35 to 55° with respect to the outer plate 140b. In the present embodiment, the inner plate 140a is slanted 45° with respect to the outer plate 140b.
[47] The first and second vortex-forming holes 141 and 142 are implemented by forming a number of blanked faces 141a, 142a in a "D"-figured cross-sectional shape. The second vortex-forming holes 142 are slanted 35 to 55° inwardly with respect to the circumferential direction. In the present embodiment, the second vortex-forming holes 142 are slanted 45° with respect to the circumferential direction.
[48] The metal fiber 150 is generally in an annular shape. The first vortical mixture gas from the nozzle holes 131 passes through the metal fiber 150. Accordingly, when combustion is conducted inside the combustion drum 130, the metal fiber 150 remains heated, thus allowing for re-ignition when fire is instantaneously extinguished by for example wind.
[49] In this structure, the combustible gas and the oxygen from the gas pipeline 115 are converted to the first vortical mixture gas as they circulate along the inside of the guider body 110. The first vortical mixture gas passes through the nozzle holes 131 via the passages 121a formed between the guide pins 121 and then is mixed with a new oxygen from the body hole 110c, thus creating a second vortical mixture gas.
[50] The second vortical mixture gas in the combustion drum 130 is ignited by the spark plug 160 and burned to create a vortical flame. The vortical flame passes through the first vortex-forming holes 141 of the combustion plate 140 to create a first external vortical flame into the combustion plate 140. As such, the first external vortical flame is created by the first vertex-forming holes 141 of the inner plate 140a slanted 35 to 55°. Accordingly, high thermal power combustion can be realized by maximally inducing air through the body hole 110c.
[51] The vortical flame passes through the second vortex-forming holes 142 of the combustion plate 140 to create the second external vortical flame. As such, the second external vortical flame is created by the second holes 142 formed toward the inside of combustion plate 140, which makes it possible to concentrate thermal power into the inside of the combustion plate 140. This fundamentally addresses a risk of extinguishment when a great amount of gas is projected, thereby achieving high thermal power combustion and causing re-combustion of an unburned gas. Thus, it is possible to maximize utilization of a heat-exchanging area of the heating container, as well as thermal efficiency.
[52] Even when fire is instantaneously extinguished by wind, it is reignited by the preheated metal fiber 150, thus preventing the combustion from stopping in any ambients.
[53] While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Industrial Applicability
[54] As described above, with the combustion system for a burner according to the first embodiment of the present invention, the combustible gas and the oxygen from the gas pipeline are converted into the first vortical mixture gas inside the guider body. The first vortical mixture gas passes through the passages of the vortex-forming wing member. As the first vortical mixture gas is then mixed with the external oxygen from the vortex-forming holes of the vortex-forming mesh, the first vortical mixture gas is converted to the second vortical mixture gas. The first vortical mixture gas is also converted to the third vortical mixture gas as it rapidly passes through the vortex- forming holes formed at the annular vortex-forming member. The second and third vortical mixture gases are burned at the upper portion inside the guider body to create the flame. The flame is projected only upwardly through the flame projecting holes of the perforated member to heat the bottom of the heating container located on the upper part of combustion system, thus increasing thermal efficiency.
[55] The gas passage is formed at the bottom of the first vortex-forming wing member, with the perforated plate removed, to induce strong vortical combustion, and brings a great amount of induced air into the inlet when a high-temperature gas (flame) is supplied upwardly, resulting in an optimal combustion condition.
[56] Furthermore, the second and third vortical mixture gases are burned between the outer surface of the perforated member and the heating container in an optimal combustion mixture ratio so that they are entirely burned in the upper portion inside the guider body. The perforated member reheated by the heat radiates radiant heat to heat from a center of the heating container to the outside thereof external, thereby increasing the thermal efficiency.
[57] In addition, even when wind blows, the fire is not extinguished since the combustion is conducted inside the guider body.
[58] According to the second embodiment of the present invention, the combustion system for a burner includes the vortex-forming guider having a number of guide pins disposed in a cylindrical shape; the combustion drum provided inside the vortex- forming guider; a combustion plate provided on the upper part of combustion drum, and having a number of first vortex-forming holes and a number of second vortex- forming holes; and the metal fiber provided inside the combustion drum, thereby creating the first external vortical flame burned inwardly in the upper portion of the combustion plate and the second external vortical flame inducing re-combustion of an unburned gas. This can achieve high thermal power, increase thermal efficiency, and conserve the fuel. Furthermore, even when fire is instantaneously extinguished by wind, continuous combustion is possible in such a windy ambient since the vortical mixture gas is reignited by the metal fiber.
