Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 2, the present embodiment provides an oven powerful burner, which includes a burner body 1, a nozzle 2, and an ignition device 3. The burner body 1 includes an intake pipe 11, a first buffer section 12, a second buffer section 13, and a rear-section closed duct 14.
One end of the nozzle 2 is communicated with the fuel gas, the other end of the nozzle is communicated with the air inlet end of the air inlet pipe 11, and the air outlet end of the air inlet pipe 11 is communicated with the air inlet end of the first buffer section 12. The air outlet end of the first buffer section 12 is communicated with the air inlet end of the second buffer section 13. The air outlet end of the second buffer section 13 is communicated with the rear section closed pipeline 14. Wherein, the second buffer section 13 is provided with a main fire hole 15, the rear section closed pipeline 14 is provided with a fire transfer hole 16, and the ignition device 3 is arranged at the adjacent position of the fire transfer hole 16. The preferred embodiment is provided with an ignition device mounting bracket 7 to facilitate the attachment of the ignition device 3 to the rear-section closed duct 14. Further, the nozzle 2 is provided with an air inlet 31, and air enters the burner main body 1 through the air inlet 31. The present embodiment further comprises an adjusting device 4 for adjusting the size of the air inlet 31. The adjusting device 4 is preferably provided with a damper 41, wherein the damper 41 is attached to the outer wall of the nozzle 2 and can rotate on its own axis, wherein the area of the damper 41 is larger than the area of the air inlet 31. Specifically, the damper 41 is rotatable on the outer wall of the nozzle 2, so that the damper 41 can block the air inlet 31 and control the size of the air inlet 31, thereby adjusting the ventilation amount of the air inlet 31. The embodiment can control the air inlet amount to control the mixing degree of gas and air, and improve the reliability and safety during combustion.
The air inlet pipe 11 of the present embodiment is preferably a radial pipe, which is provided to increase the pressure of the air flow, increase the mixing rate between the fuel gas and the air, and prevent the backflow of the gas, thereby preventing the occurrence of the backfire in the burner of the present embodiment. However, after the gas and air are pressurized by the radiation tube, the gas pressure of the gas flow becomes very high and the flow rate becomes very high, so that the gas pressure inside the burner body 1 is unevenly distributed, and the phenomenon of unstable combustion is likely to occur. And first buffer segment 12 and second buffer segment 13 can slow down the inside atmospheric pressure of combustor main part 1, reduce gaseous velocity of flow for the flame state of burning on the main fire hole 15 can reach steady state, and the burning is more abundant, thereby reduces the emission of carbon monoxide, suppresses nitrogen oxide's formation, and the gas flows smoothly moreover and can effectively reduce the combustion noise.
The first buffer section 12 and the second buffer section 13 designed in this embodiment are used to slow down the gas pressure inside the burner body 1. The first buffer section 12 is used for buffering the gas pressure at the front section of the decompression burner main body 1, and the second buffer section 13 is used for buffering the gas pressure at the rear section of the decompression burner main body 1. The first buffer section 12 of this embodiment is a 90 ° bend. The second buffer section 13 of this embodiment is a 180 ° elbow. Wherein, the return bend can reduce the velocity of flow of gas, and first buffer segment 12 is the return bend of 90, can greatly reduced the velocity of gas air current. The second buffer section 13 is designed as a 180 ° elbow, the length of which is much longer than that of the first buffer section 12, so that the gas flow in the burner body 1 is more uniform and stable.
Specifically, as shown by the arrows in fig. 1, the gas first passes through the nozzle 2 and then enters the intake pipe 11, and in the process, the air passes through the intake port 21 of the nozzle 2 and is injected into the intake pipe 11 together with the gas. At this time, the gas and the air are mixed in the intake pipe 11 and then flow to the first buffer section 12 as shown by an arrow in fig. 1, and the first buffer section 12 can buffer the gas pressure in the front section inside the decompression burner main body 1. The gas and air are then decompressed in the first buffer section 12 and enter the second buffer section 13. At this time, the second buffer section 13 can buffer the gas pressure in the rear section inside the decompression burner body 1, when the gas reaches the rear section closed pipeline 14, the gas emerges from the fire transfer hole 16, at this time, the ignition device 3 will ignite the fire transfer hole 16, and then the flame on the main fire hole 15 will be ignited after the fire transfer hole 16 is ignited. The first buffer 12 of this embodiment provides a gas air mixing district, and the second buffer 13 provides a secondary gas air mixing district, makes and mixes more fully between gas and the air, security and reliability when improving the gas combustion, and first buffer 12 and second buffer 13 can make the even and unobstructed flow of gas pressure distribution of combustor main part 1 inside moreover, and the unstable problem of flame when the high-power combustor of solution in the oven burns.
A front section pipeline 17 is arranged between the first buffer section 12 and the second buffer section 13, and a duplex fire hole 18 for maintaining stable flame is arranged on the front section pipeline 17. When the main fire holes 15 are ignited to burn, the double fire holes 18 are ignited, so that the fuel gas is burnt on the double fire holes 18. Specifically, the gas passes through first buffer segment 12, and the gas velocity of flow is still very fast, sets up pair fire hole 18 and can stabilize the flame state on the main fire hole 15, prevents that main fire hole 15 from appearing from the phenomenon of flame and disconnected fire.
The present embodiment is also preferably provided with a structural reinforcement 5 for connecting and fixing the front-stage duct 17 and the rear-stage closed duct 14. The structure reinforcement 5 mainly connects the front section pipeline 17 and the rear section closed pipeline 14 which strengthen the left and right sides of the burner main body 1, and prevents the phenomenon that the horizontal position of the burner main body 1 is changed due to the softening and drooping of the burner after the burner main body is burnt by high temperature.
The burner body 1 of the present embodiment is preferably an integrally formed member, which avoids the disadvantages of welding and sealing, and does not require complex machine installation, thereby facilitating replacement and disassembly. The present embodiment is further preferably provided with a mounting fixture 6, and the mounting fixture 6 mounts and fixes the burner main body 1 inside the oven.
The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
