[0003] The applicant has previously disclosed several related technologies: Patent publication number CN115183268A proposes a driving method for the combined combustion of fossil fuels and nuclear-chemical energy. This method involves introducing fossil fuels and combustion-supporting gases into an alternating electromagnetic field, causing the dissociated light nuclei to collide and trigger a nuclear fusion reaction, releasing nuclear energy. Simultaneously, the plasma-state fuel and combustion-supporting gas achieve ultra-fast combustion after leaving the electromagnetic field, significantly improving the energy release effect.

All of the above technologies are based on warm nuclear fusion fossil fuel combined combustion technology, and their theoretical system has been elaborated in detail in monographs and is publicly known.

[0004] However, the burner of patent CN221526605U has the following problems when installed and used in glass melting furnaces:

[0005] Poor insulation in glass melting furnaces leads to excessively high ambient temperatures around the burners (60-150℃ in the side-burning and low-temperature zones of small furnaces, and 250-350℃ near the nozzles), posing serious safety hazards and damage to high-voltage and high-temperature cables. During operation, the flame column has a certain length, and the upward movement of the flame at its end causes heat loss from the upper part of the furnace top, resulting in heat loss. Utility Model Content

[0006] The purpose of this invention is to provide a dual-speed combustion torch for gas thermonuclear fusion composite combustion, which can reduce thermal radiation damage to electrode components and cables, improve the safety and reliability of electrode components, reduce heat loss at the furnace top, increase the heat energy receiving area of ​​the molten glass flame inside the furnace, and increase energy saving effect.

[0011] The safety junction box is located at the rear end of the gun housing, and the safety junction box has a wiring port; the multiphase electrode assembly is distributed between the gun housing and the central gas gun tube, and its connecting cable passes through the wiring port.

[0012] Furthermore, based on the aforementioned scheme, the multiphase electrode assembly includes electrode heads and electrode rods. Multiple electrode heads are located inside the outer nozzle and circumferentially distributed outside the central nozzle. Multiple electrode rods are connected one-to-one with multiple electrode heads and pass through the gun housing and the central gas gun tube. The connecting end of the electrode rod extends into the safety junction box and connects to the connecting cable. Electrode support frames are respectively provided at both ends inside the gun housing to support and fix the electrode rods.

[0013] Furthermore, based on the aforementioned scheme, the junction box is connected to the rear end of the gun housing via a connecting flange.

These two gas streams can be of different qualities and pressures, enabling adjustable flame diameter and length. By eccentrically positioning the external nozzle relative to the central nozzle, with the external nozzle eccentrically downwards, a large volume of gas is forced downwards, preventing flame upward movement and reducing furnace top losses. Simultaneously, the horizontally positioned elliptical nozzle results in a flattened and widened flame within the same cross-sectional area, increasing the heat-receiving area for the molten glass inside the furnace and thus enhancing energy efficiency. Furthermore, by installing a safety junction box at the rear of the nozzle housing, the electrode rods of the multiphase electrode assembly are extended rearwards and wired within the safety junction box, exiting through the wiring port. This avoids direct contact with high-temperature areas, reducing heat radiation damage to the high-voltage electrode assembly and cables, thereby improving the safety and reliability of the high-voltage electrode assembly system.

Detailed Implementation

[0028] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0029] Please refer to Figures 1-4 The diagram shows the overall structure of a dual-speed combustion torch for thermonuclear fusion combined combustion.

[0030] This embodiment provides a dual-speed combustion torch for gas thermonuclear fusion composite combustion, including a gun shell 1, a central gas gun tube 2, a nozzle 3, a safety junction box 4, and a multiphase electrode assembly 5;

[0031] The central gas gun tube 2 is arranged inside the gun housing 1 along the axial direction of the gun housing 1, and forms an external gas passage 6 between the central gas gun tube 2 and the gun housing 1.

[0032] The nozzle 3 is located at the front end of the gun housing 1 and includes an outer nozzle 31 and a central nozzle 32. The outer nozzle 31 is located at the outlet end of the gun housing 1 and is connected to the gun housing 1. The central nozzle 32 is located at the outlet end of the central gas gun tube 2 and is connected to the central gas gun tube 2. The nozzle orifice of the outer nozzle 31 is eccentrically downward relative to the central nozzle 32 and is elliptical with its major axis set horizontally.

[0033] The safety junction box 4 is located at the rear end of the gun housing 1, and the safety junction box 4 has a wiring port 41; the multiphase electrode assembly 5 is distributed between the gun housing 1 and the central gas gun tube 2, and its connecting cable 7 passes through the wiring port 41.

[0034] The following will further describe a dual-speed combustion torch for gas thermonuclear fusion combined combustion, which is an exemplary embodiment of this invention.

[0035] In some embodiments, the aforementioned central gas nozzle 2 is disposed inside the gun housing 1 along the axial direction of the gun housing 1, forming an external gas passage 6 between it and the gun housing 1. The gas flows into the combustion torch in two streams: one is the gas flow connected through the first quick connector 21 on the central gas nozzle 2, and the other is the main high-flow gas flow connected through the second quick connector 11 sealed to the gun housing 1. The two gas streams can be of different qualities and pressures, allowing for adjustable flame diameter and length. This dual gas supply from the central gas nozzle 2 and the external gas passage 6 lays the foundation for the combined release of thermonuclear fusion reaction and chemical combustion of the gas, enabling nuclear energy gain, saving gas, and reducing CO2 emissions.

[0036] The aforementioned nozzle 3 is located at the front end of the gun housing 1, including an outer nozzle 31 and a central nozzle 32. The outer nozzle 31 is located at the outlet end of the gun housing 1 and communicates with the gun housing 1; the central nozzle 32 is located at the outlet end of the central gas gun tube 2 and communicates with the central gas gun tube 2; the nozzle orifice of the outer nozzle 31 is eccentrically downward relative to the central nozzle 32 and is elliptical with its major axis horizontally set. By setting the nozzle orifice of the outer nozzle 31 to be eccentrically downward and elliptical with its major axis horizontally set, a large amount of gas is forced out downward, resulting in a flattened and widened flame under the same cross-sectional area, reducing flame upward movement and lowering heat loss at the furnace top; at the same time, the flat flame column can intersect, thereby increasing the temperature, increasing the heat energy receiving area of ​​the molten glass, improving energy saving effect and the service life of the furnace top refractory material.

[0037] The aforementioned safety junction box 4 is located at the rear end of the gun housing 1. The safety junction box 4 has a connection port 41, preferably two ports 41, to facilitate the routing of multiple cables. The multiphase electrode assembly 5 is distributed between the gun housing 1 and the central gas nozzle 2, and its connecting cable 7 exits through the connection port 41. Through this structural design, the multiphase electrode assembly 5 can be directly or indirectly cooled by the low-temperature gas introduced into the external gas passage 6 and the central gas nozzle 2. Simultaneously, the connecting cable 7 exits through the connection port 41 of the safety junction box 4, avoiding direct contact with high-temperature areas, reducing thermal radiation damage, and significantly improving the safety and reliability of the high-voltage electrode system.

[0038] In a preferred embodiment, the multiphase electrode assembly 5 includes electrode heads 51 and electrode rods 52. Multiple electrode heads 51 are located inside the outer nozzle 31 and circumferentially distributed outside the central nozzle 32, forming a uniform thermonuclear fusion electric field in the nozzle 3 outlet region, ensuring stable light nucleus collision reactions and improving nuclear energy release efficiency. Multiple electrode rods 52 are connected one-to-one with multiple electrode heads 51 and pass through the gun housing 1 and the central gas gun tube 2. The connecting ends of the electrode rods 52 extend into the safety junction box 4 and connect to the connecting cable 7, further distancing them from the high-temperature nozzle 3 region and reducing the risk of thermal damage. Electrode support frames 53 are respectively provided at both ends inside the gun housing 1 to support and fix the electrode rods 52, enhancing the structural stability of the electrode assembly and preventing electric field disturbances caused by vibration or high-temperature deformation.

[0039] In a preferred embodiment, the junction box is connected to the rear end of the torch housing 1 via a connecting flange 42. The connecting flange 42 ensures a sealed connection between the safety junction box 4 and the rear end of the torch housing 1, preventing gas leakage, improving the safety of the combustion torch, and facilitating the disassembly and assembly of the safety junction box 4, which is beneficial for the maintenance and replacement of the electrode assembly and cables.

[0040] As a preferred embodiment, the length of the gun housing 1 is 30-50cm, which allows the electrode connection part in the high-voltage electrode assembly to be 30-50cm away from the cable behind the flame nozzle 3, effectively avoiding the high temperature area of ​​250-350℃ near the nozzle 3, reducing the aging damage of heat radiation to the electrode and cable, and extending their service life.

[0041] As a preferred embodiment, a bidirectional adjustment bracket 8 is provided below the aforementioned gun casing 1. The bidirectional adjustment bracket 8 allows the combustion torch to move up and down or tilt and swing. The bidirectional adjustment bracket 8 can flexibly adjust the vertical height and swing angle of the flame column, enabling the flame to adapt to different furnace structures and the heating requirements of molten glass, optimizing the heat radiation range, and further reducing heat waste.

[0042] It should be noted that the aforementioned bidirectional adjustment bracket 8 may specifically include a support plate 86, two support rings 85, a mounting plate 81, a swing column, and two threaded adjustment rods 84. The mounting plate 81 is used to install and fix the bidirectional adjustment bracket 8 and the combustion torch. The swing column has a double-sleeve structure, with the bottom of the inner sleeve 82 fixed on the mounting plate 81 and the outer sleeve 83 movably sleeved on the outside of the inner sleeve 82. One of the threaded adjustment rods 84 is threaded through the mounting plate 81 and extends upward to connect with the top of the outer sleeve 83. By rotating the threaded adjustment rod 84, the height of the outer sleeve 83 can be adjusted by moving it up and down relative to the inner sleeve 82. The two support rings 85 are installed on the support plate 86, one of which is sleeved on the outside of the outer nozzle 31 and the other is sleeved on the outside of the gun shell 1. The support ring 85 sleeved on the nozzle 3 is connected to the outer sleeve 83 through a swing bracket 87. The rear end of the support plate 86 is threadedly connected to the bracket on the outer wall of the outer sleeve 83 through another threaded adjustment rod 84. By rotating the threaded adjustment rod 84, the up and down swing angle of the combustion torch can be adjusted.

[0043] As a preferred embodiment, the inner cavities of both the central nozzle 32 and the outer nozzle 31 are cylindrical-pyramidal structures. The cylindrical-pyramidal structure allows the gas to flow stably within the nozzle 3 before being accelerated and ejected, enhancing the uniformity of the mixing of the gas and the combustion-supporting gas and improving combustion efficiency; at the same time, it reduces turbulent losses of the gas within the nozzle 3, thereby reducing energy consumption.

[0044] In a preferred embodiment, an air-cooled / water-cooled baffle 9 is fitted onto the outlet end of the external nozzle 31. The air-cooled / water-cooled baffle 9 specifically includes a hollow annular housing, an inlet pipe, and an outlet pipe. The hollow annular housing is fitted onto the outlet end of the external nozzle 31, allowing cold air or cooling water to be introduced through the inlet pipe for cooling, and then circulated through the outlet pipe to maintain cooling. When air-cooled, multiple air holes can be circumferentially opened in the hollow annular housing, all facing the outer wall of the external nozzle 31. The air-cooled / water-cooled baffle 9 effectively blocks direct heat radiation from the flame and conductive heat from high-temperature flue gas, protecting the external nozzle 31 and the front end components of the gun housing 1 from high-temperature damage and extending their service life in environments of 250-350℃.

[0045] In a preferred embodiment, the central gas nozzle 2 is connected to a feed regulator 22. The feed regulator 22 is used to enable the central gas nozzle 32 to move along the axial direction of the dual-speed gas torch shell.

[0046] In this embodiment, two streams of gas are connected through the first quick connector 21 and the second quick connector 11, respectively, and flow in the gap between the gun shell 1 and the central gas gun tube 2 and in the central gas gun tube 2, which can cool the electrode rod 52 and the high-voltage connecting cable. The multiphase electrode assembly 5 forms a thermonuclear fusion electric field region near the nozzle 3, causing the light nuclei dissociated from the gas to collide and release nuclear energy. After leaving the electric field region, the gas is ejected and burned through the outer nozzle 31 and the central nozzle 32. Due to the eccentric elliptical design of the nozzle 31, the flame is flattened and widened and the upward movement is reduced, realizing the combined release of chemical energy and nuclear energy, achieving the effect of saving gas and reducing CO2 emissions.
