A gas burner gas supply system

Abstract

This invention provides a gas supply system for a gas burner, relating to the field of gas burner technology. The system includes: a gas cylinder assembly, a pressure reducing valve, a solenoid valve, a connecting pipe, a burner assembly, and a support assembly. By setting the outlet pressure of the pressure reducing valve to a medium pressure of 1-5 psi, this system significantly increases the flow rate and pressure variation of the gas entering the solenoid valve. Furthermore, the system is equipped with multiple nozzles. When these nozzles input gas into the burner head injector, the medium-pressure gas can better mix the surrounding air with the gas before entering the burner, achieving a thorough mixing of gas and air. This effectively reduces the risk of open flames or floating flames at the burner head during reverse combustion and lowers the possibility of excessive flue gas emissions. An angle adjustment assembly changes the combustion angle of the burner assembly, allowing the burner assembly to be adjusted to a suitable angle position during reverse or lateral combustion, preventing exhaust gas accumulation near the burner head.

Description

Technical Field

[0001] This invention relates to the field of gas burner technology, and more specifically, to a gas burner gas supply system. Background Technology

[0002] Outdoor heaters are widely used for heating open environments such as courtyards, terraces, and outdoor commercial spaces. Gas infrared heaters, due to their high thermal efficiency and rapid heating, have become one of the main methods of outdoor heating. Their heat output power usually needs to reach more than 30,000 BTU to meet the heating requirements of large outdoor spaces.

[0003] Existing outdoor heaters typically use conventional low-pressure gas supply systems, such as pressure-reducing valves set at approximately 0.4 psi. When the burner is facing upwards, the exhaust gas produced can be naturally discharged upwards, resulting in a relatively stable combustion state. However, when the burner is facing downwards or sideways, the following technical problems arise: due to the low gas flow rate of the low-pressure supply, the gas and air are difficult to mix fully in the injector and burner head. In addition, the exhaust gas produced cannot diffuse quickly and evenly into the surrounding air, leading to a significant reduction in combustion efficiency. Furthermore, because the gas and air mixing effect is poor, open flames and floating flames are prone to occur during combustion, resulting in excessive emissions of flue gas (especially carbon monoxide).

[0004] Therefore, there is an urgent need to propose a gas supply system for gas burners. Summary of the Invention

[0010] As a further embodiment of the present invention: multiple furnace chambers are arranged on a fixed frame and penetrate into the furnace head body.

[0023] See Figures 1-7 An embodiment of the present invention provides a gas burner supply system, comprising: a gas cylinder assembly 1, a pressure reducing valve 5, a solenoid valve 6, a connecting pipe 7, a burner assembly 2, and a support assembly 3. The gas cylinder assembly 1 is connected to the pressure reducing valve 5 via a pipe. The pressure reducing valve 5 is connected to the solenoid valve 6. The solenoid valve 6 is connected to the burner assembly 2 via the connecting pipe 7. The solenoid valve 6 is located downstream of the pressure reducing valve 5 and is used to control the on / off flow of gas. The solenoid valve 6 is a stopcock solenoid valve. The pressure reducing valve 5, the solenoid valve 6, and the connecting pipe 7 are all mounted on the support assembly 3. The support assembly 3 is mounted on the gas cylinder assembly 1, and the burner assembly 2 is mounted on the support assembly 3. The support assembly 3 is equipped with an angle adjustment assembly 4 for changing the angle of the support assembly 3 to change the combustion angle of the burner assembly 2. The pressure of the pressure reducing valve 5 is set to 1-5 psi. The burner assembly 2 includes multiple nozzles 21 and a burner body 22. The multiple nozzles 21 are connected to the gas outlet end of the connecting pipe 7 through nozzle seats 211. The burner body 22 is installed on the support assembly 3 through a fixing bracket 23. The burner body 22 has multiple furnace chambers 221 with the same number as the nozzles 21. Each furnace chamber 221 is equipped with a burner ejector tube 221a. The multiple nozzles 21 are respectively aligned with each burner ejector tube 221a.

[0024] In this embodiment, when ignited, the solenoid valve 6 is opened, and the gas is reduced to 1-5 psi by the pressure reducing valve 5 and then ejected through the multi-nozzle 21. Air is drawn in once at the ejector gap and enters the furnace head ejector tube 221a. Compared to the conventional 0.4psi gas supply pressure in existing technologies, this system significantly increases the flow rate and pressure variation of gas entering the solenoid valve 6 by setting the outlet pressure of the pressure reducing valve 5 to a medium pressure of 1-5psi. Furthermore, the system is equipped with multiple nozzles 21, which are connected to multiple connecting pipes 7 via nozzle seats 211. When the multiple nozzles 21 input gas into the burner injector 221a, the medium-pressure gas can better mix with the surrounding air before entering the burner, achieving a thorough mixing of gas and air. This results in more complete combustion, effectively reducing the risk of open flames and floating flames at the burner head during reverse combustion and lowering the possibility of excessive flue gas emissions. In addition, the angle adjustment component 4 changes the combustion angle of the burner assembly 2, allowing the burner assembly 2 to be adjusted to a suitable angle position when the product is burning in reverse or sideways, facilitating the smooth discharge of exhaust gas and preventing its accumulation near the burner head. This meets the needs of different installation environments and usage requirements.

[0025] Furthermore, multiple nozzles 21 are configured one-to-one with multiple furnace chambers 221, so that each nozzle 21 and the corresponding burner head ejector pipe 221a form an independent gas and air mixing channel, resulting in more uniform gas distribution and similar combustion states in each furnace chamber 221. This avoids the problem of uneven local mixing caused by concentrated gas injection when supplying gas from a single nozzle 21. In addition, since medium-pressure gas supply is used, even if the connecting pipe 7 has a smaller channel diameter, it can still meet the gas flow requirements of the high-power burner, thereby effectively solving the pipeline flow restriction problem and reducing pipeline costs.

[0026] See Figures 1-5 Optionally, the support assembly 3 includes a lower support pipe 31, an upper support pipe 32, and a burner head support pipe 33; the upper and lower ends of the lower support pipe 31 are connected to the upper support pipe 32 and the gas cylinder assembly 1, respectively; the upper part of the upper support pipe 32 is connected to the burner head support pipe 33; the burner head support pipe 33 is connected to the fixing frame 23; the angle adjustment assembly 4 is disposed between the upper support pipe 32 and the burner head support pipe 33; the pressure reducing valve 5 and the solenoid valve 6 are both disposed on the upper support pipe 32; and the connecting pipe 7 is disposed inside the upper support pipe 32 and the burner head support pipe 33.

[0027] In this embodiment, the upper support pipe 32 and the lower support pipe 31 are vertically arranged, and the burner head support pipe 33 is inclinedly arranged on the upper support pipe 32. The burner assembly 2 is arranged at the upper end of the burner head support pipe 33. The connecting pipe 7 and the pipe connecting the pressure reducing valve 5 and the gas cylinder assembly 1 are evenly arranged inside the upper support pipe 32, the lower support pipe and the burner head support pipe 33 of the support assembly 3. The support assembly 3 effectively protects each valve body and pipe, avoiding damage to the gas supply components caused by external collisions or environmental factors. A detachable maintenance plate is provided on the upper support pipe 32. The position of the maintenance plate corresponds to the position of the pressure reducing valve 5 and the solenoid valve 6. When it is necessary to repair or replace the gas supply equipment inside the support assembly 3, the maintenance plate can be opened to maintain or replace the pressure reducing valve 5 and the solenoid valve 6.

[0028] See Figure 3 and Figure 4Optionally, the upper support tube 32 has a through groove 321 on its upper part; the angle adjustment component 4 includes an auxiliary block 41, a rotating shaft 42, a positioning pin 43, and a receiving cylinder 44; the auxiliary block 41 passes through and fixes the bracket 23 in the through groove 321, the burner head support tube 33 is located inside the auxiliary block 41, the rotating shaft 42 passes through the burner head support tube 33 and the auxiliary block 41, the burner head support tube 33 is rotatably connected to the rotating shaft 42, the auxiliary block 41 has multiple connecting holes 411, the multiple connecting holes 411 are arranged in an arc shape with the rotating shaft 42 as the center, the receiving cylinder 44 is fixedly inserted into the burner head support tube 33, the positioning pin 43 passes through the receiving cylinder 44 and enters the corresponding connecting hole 411, so as to position the burner head support tube 33 at different combustion angles, and by inserting the positioning pin 43 into different connecting holes 411, the combustion angle of the burner head support tube 33 relative to the upper support tube 32 can be changed.

[0029] In this embodiment, the auxiliary block 41 is fixedly installed in the through groove 321, and the burner head support tube 33 also passes through the through groove 321 and is rotatably connected to the auxiliary block 41 via the rotating shaft 42. When the positioning pin 43 is not installed, the burner head support tube 33 can rotate relative to the upper support tube 32 around the rotating shaft 42. The user can adjust the angle of the burner head support tube 33 relative to the upper support tube 32 according to actual usage needs, and then insert the positioning pin 43 into the corresponding connection hole 411 and pass it into the receiving cylinder 44, thereby fixing the combustion angle of the burner assembly 2. It should be noted that at a higher combustion angle, the exhaust gas of the burner assembly 2 is discharged more smoothly and the heat radiation range is wider. Preferably, the auxiliary block 41 has connection holes 411 on both sides, and the multiple connection holes 411 on both sides are symmetrical to each other. When installing the positioning pin 43, the positioning pin 43 is inserted into the connection hole 411 on one side, the receiving cylinder 44 and the connection hole 411 on the other side in sequence, thereby improving the positioning firmness of the positioning pin 43 on the furnace head support tube 33. The positioning pin 43 can be a screw, and a nut is threaded to the bottom of the screw to prevent the positioning pin 43 from falling off.

[0030] See Figure 1 and Figures 3-4 Optionally, one end of the burner head support tube 33 is connected to a counterweight 331, and the counterweight 331 and the burner assembly 2 are located on both sides of the upper support tube 32.

[0031] In this embodiment, since the burner assembly 2 itself has a certain weight and is installed at one end of the burner head support tube 33, it is easy for the burner head support tube 33 to be unbalanced in force on both sides of the rotating shaft 42. By setting a counterweight 331 at the other end of the burner head support tube 33, the weight distribution on both sides of the burner head support tube 33 is made more balanced, which effectively prevents the burner head support tube 33 from rotating or overturning unexpectedly around the rotating shaft 42 due to the excessive weight of the burner assembly 2, and ensures the stability of the burner assembly 2 under various combustion angles.

[0032] See Figures 5-7 Optionally, multiple furnace chambers 221 are mounted on a fixed frame 23 and extend into the furnace head body 22. The fixed frame 23 is provided with multiple fixed plates 24, the number of which is the same as the number of furnace chambers 221. The fixed plates 24 are C-shaped and laterally cover the end of the furnace head ejector tube 221a of the furnace chamber 221. The nozzle 21 is fixedly installed on the fixed plate 24 and located inside the fixed plate 24. An ejection gap is left between the nozzle 21 and the opening of the furnace head ejector tube 221a. When the gas is ejected from the nozzle at high speed with medium pressure, a negative pressure zone is formed at the ejection gap. The surrounding primary air is drawn into the furnace head ejector tube 221a under the action of this negative pressure and is fully mixed with the gas.

[0033] In this embodiment, a C-shaped fixing plate 24 is laterally mounted on the end of the furnace head ejector tube 221a, and the nozzle 21 is fixedly installed on the fixing plate 24 and located inside the fixing plate 24, thereby forming an ejector space that laterally encloses the nozzle 21 and the fixing plate 24. On the one hand, the side wall of the C-shaped fixing plate 24 physically isolates adjacent nozzles and corresponding ejector tubes from each other, forming independent ejector spaces, avoiding mutual interference or cross-flow of gas jets ejected from adjacent nozzles 21. On the other hand, the lateral enclosure of the fixing plate 24 can effectively block lateral cold air or external airflow from directly blowing into the ejector gap, preventing the amount of primary air replenishment from fluctuating due to external wind force fluctuations, preventing the high-speed gas jet from being blown away and deflected, thereby enhancing the stability of the negative pressure zone in the ejector gap, making the mixing and combustion of gas and air in each furnace chamber 221 more uniform and stable.

[0034] See Figures 5-7 Optionally, the bottom of the fixed plate 24 has an air damper 26 that extends from the inner wall of the fixed plate 24 to the inlet of the furnace head ejector tube 221a.

[0035] In this embodiment, for example, when there is lateral cold wind or airflow disturbance in the outdoor environment, the damper 26 can effectively block or reduce the direct impact of cold wind on the gas-air mixture in the injector tube, thereby effectively solving and preventing the problem of difficult cold ignition and ensuring the ignition success rate and combustion stability of the burner assembly 2.

[0036] See Figures 5-7 Optionally, a protective plate 27 is fixedly connected to the bottom of the mounting bracket 23. The protective plate 27 is located at the bottom of the furnace cavity 221 outside the burner body 22. The protective plate 27 is used to block the high temperature generated by some parts of the burner assembly 2 from directly radiating downward or to the side and downward, so as to protect other surrounding parts below the protective plate 27 from the effects of high temperature.

[0037] See Figures 1-3 and Figures 5-7Optionally, a reflector plate 25 is detachably installed on the side of the burner body 22. The reflector plate 25 is fan-shaped and detachably installed on the side of the burner body 22, covering the upper side of the burner in the shape of a brim. Multiple reflector plates 25 can be installed around the edge of the burner body. The fan-shaped reflector plate 25 can reflect and concentrate the infrared radiation heat generated by the combustion of the burner body 22 downward or to the target heating area, reducing the loss of heat to non-heating areas, thereby improving the thermal radiation efficiency and heating effect of the burner assembly 2. Furthermore, the detachable design of the reflector plate 25 allows the user to change the position of the reflector plate 25 on the burner body 22 according to actual usage needs. A burner protective net is also provided below the burner body 22 to protect the burner body 22.

[0038] See Figure 2 Optionally, the connecting pipe 7 can be a corrugated pipe. Since this system uses medium-pressure gas supply of 1-5psi, the gas has a higher flow rate and pressure compared to conventional pressure gas supply. Therefore, the connecting pipe 7 can be a corrugated pipe with a smaller channel diameter to meet the gas flow requirements of the high-power burner.

[0039] In this embodiment, the corrugated pipe has good flexibility and bendability, which makes it easy to lay out and adjust the direction inside the upper support pipe 32 and the furnace head support pipe 33. It can adapt to the relative displacement and slight deformation of the furnace head support pipe 33 during the angle adjustment process, which makes it easier for workers to assemble the product. In addition, the use of corrugated pipe also reduces pipeline costs.

[0040] See Figure 1 Optionally, the gas cylinder assembly 1 includes a protective frame 11 and a gas cylinder body 12. The protective frame 11 covers the outside of the gas cylinder body 12, and the support assembly 3 is installed on the protective frame 11.

[0041] In this embodiment, the protective frame 11 is placed on the outside of the gas cylinder body 12, providing external physical protection for the gas cylinder body 12. The protective frame 11 is placed on the ground, the support component 3 is installed on the protective frame 11, and the bottom end of the lower support tube 31 is fixedly connected to the protective frame 11. The protective frame 11 provides stable support for components such as the support component 3 and the burner component 2. The gas cylinder is connected to the pressure reducing valve 5 through a pipeline, which passes upward through the protective frame 11 and enters the lower support tube 31.

[0042] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
