[0001] This utility model relates to the field of burner technology, specifically to a jet-type gas burner. Background Technology

[0002] The DYQ series jet gas burner is a new type of high-performance gas burner. Unlike previous sleeve-type and multi-tube gas nozzles, it adopts a uniquely designed annular flat slit gas jet method, which enables the gas and air at the burner outlet to quickly generate strong and uniform mixing, creating a gas-air mixture flow that is particularly suitable for combustion.

[0003] During the use of DYQ series jet-type gas burners, the burner is installed on the furnace body so that the nozzle pipe can discharge harmful gases. However, when connecting the nozzle pipe to the furnace body, the uneven surface of the furnace body can cause gaps to appear during the connection, leading to the risk of harmful gases leaking into the room and posing a life-threatening danger to users. Therefore, jet-type gas burners are particularly needed to solve the above problems. Utility Model Content

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] like Figures 1 to 4 As shown, an embodiment of this utility model provides a jet-type gas burner, comprising:

[0037] Gas reactor shell 1;

[0038] Gas inlet pipe 2 is installed on the outer surface of the gas reaction shell 1;

[0039] Air cylinder 3 is installed on the outer surface of the gas reaction shell 1;

[0040] Air inlet pipe 4 is installed on the outer surface of air cylinder 3;

[0041] Nozzle pipe 5 is installed on the outer surface of air cylinder 3;

[0042] Flame stabilizer 7 is installed in the inner cavity of air cylinder 3;

[0043] The electric control valve 10 is installed on the outer surface of the gas inlet pipe 2.

[0044] The gas reaction shell 1 is a chamber for the combustion of gas and air. The gas inlet pipe 2 is connected to an external gas pipe, and the air inlet pipe 4 is connected to an external air pipe. The electric control valve 10 can quickly open and close the gas inlet pipe 2. The flame stabilizer 7 can ensure that the combustion flame is uniform and stable. The nozzle pipe 5 can discharge the harmful gases generated during combustion.

[0045] like Figure 2 As shown, an ignition rod 6 is installed on the outer surface of the air cylinder 3. One end of the ignition rod 6 is located on the outer surface of the air cylinder 3, and the ignition rod 6 is located inside the air cylinder 3 and connected to the inner cavity of the gas reaction shell 1. The ignition rod 6 has a built-in flame detector, and the ignition end is located in the gas reaction shell 1, which can realize automatic ignition.

[0046] like Figure 2 As shown, a regulating valve 8 is installed at the other end of the gas reaction shell 1. The regulating end of the regulating valve 8 is located in the inner cavity of the gas reaction shell 1 and connected to the flame stabilizer 7. The rotating end of the regulating valve 8 is installed on the outside of the gas reaction shell 1, and the working end is installed in the inner cavity of the gas reaction shell 1, which can adjust the length of the flame during combustion.

[0047] like Figure 2 As shown, the gas reaction shell 1 is connected to the gas inlet pipe 2, the air cylinder 3 is connected to the air inlet pipe 4, and the other end of the gas reaction shell 1 is located in the inner cavity of the air cylinder 3.

[0048] Based on the above, the technical performance comparison values ​​for the DYQ type burner are as follows:

[0049]

[0050] Firstly,

[0051] At a constant pressure, the effect of changes in air and gas temperature on their mass flow rate is expressed by the following formula:

[0052]

[0053] As shown in the table above, when the working pressure or preheating temperature of the gas and air differs from the rated pressure and rated temperature, the combustion capacity and excess air coefficient of the burner will change. To ensure the burner always operates at a suitable excess air coefficient, the pressures of the gas and air should be adjusted to match each other under different operating conditions.

[0054] Secondly,

[0055] An increase in gas temperature will lead to a decrease in its mass flow rate. When air or gas is preheated, the pressure of the air or gas before the burner needs to be adjusted to achieve the rated burner capacity and match the mass flow rate ratio of air and gas. At the preheating temperature t, to offset the effect of temperature increase on the gas mass flow rate, the pressure of the gas before the burner needs to be adjusted using the following expression:

[0056]

[0057] like Figure 3 As shown, an mounting plate 9 is installed on the outer surface of the nozzle pipe 5.

[0058] like Figure 4 As shown, a sensor 12 is installed on the outer surface of the gas inlet pipe 2, a sensor 13 is installed on the outer surface of the air inlet pipe 4, and an alarm 11 is installed on the outer surface of the electric control valve 10. Both the gas inlet pipe 2 and the air inlet pipe 4 are equipped with sensors 12 and 13. These sensors are gas sensors that can detect gas leaks. When a gas leak occurs, sensors 12 and 13 will detect it, thereby controlling the electric control valve 10 to close the gas inlet pipe 2, and simultaneously activating the alarm 11.

[0059] like Figure 4 As shown, a sealing gasket 14 is glued to the outer surface of mounting plate 9, and mounting plate 15 is installed on the outer surface of mounting plate 9 by bolts 16. A sealing gasket 17 is fitted on the outer surface of mounting plate 15.

[0060] Sealing gasket 14 can increase the sealing between mounting plate 19 and mounting plate 2 15 to prevent the leakage of harmful gases. Sealing gasket 2 17 ensures the sealing while guaranteeing the stability of the bolt 16 connection.

[0061] like Figure 4 As shown, a sealing gasket 3 18 is glued to the outer surface of mounting plate 2 15, and an expansion bolt 19 is installed on the outer surface of mounting plate 2 15. A sealing gasket 4 20 is fitted onto the outer surface of the expansion bolt 19. The expansion bolt 19 makes the connection between the equipment and the fireplace more stable, the sealing gasket 3 18 increases the sealing between mounting plate 2 15 and the fireplace, and the sealing gasket 4 20 has the same effect as the sealing gasket 2 17.

[0062] Working principle: First, install mounting plate 19 on the fireplace through mounting plate 215. The nozzle pipe 5 extends into the fireplace. Then, first open the air inlet pipe 4 to supply a small amount of air. Then, the open flame extends into the burner brick to ignite the ignition rod 6. Next, open the gas inlet pipe 2 to supply gas, thereby turning on the burner. The ratio between gas and air is adjusted by the regulating valve 8, thereby adjusting the length of the flame jet. The flame stabilizer 7 can make the flame uniform and stable. When shutting down, first close the gas inlet pipe 2 and then close the air inlet pipe 4.

[0063] When in use, if a gas leak occurs in the gas inlet pipe 2 or the air inlet pipe 4, sensor 12 and sensor 23 will detect the gas leak, thereby causing the electric control valve 10 to operate and close the gas inlet pipe 2. At the same time, the alarm 11 will sound an alarm.

[0064] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
