Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to an energy-saving burner. Background Art

[0002] M-type permanent ferrite is currently the most widely used and consumed permanent magnet material. M-type permanent ferrite magnets are manufactured using the following process: Iron oxide is first mixed with Sr or Ba carbonates, and then pre-sintered to produce a ferrite-forming material. The pre-sintered material is then coarsely pulverized to produce a coarse ferrite powder, which is then processed through subsequent manufacturing processes depending on the intended application.

[0003] Currently, pre-firing is mostly performed in rotary kilns. The kiln's combustion system typically uses a reaction between natural gas and air to achieve the high temperatures required for the ferritization reaction (generally 1200-1350°C). During conventional combustion, natural gas and air are introduced simultaneously into the burner, with the oxygen content of the air at 21%. Under these conditions, the natural gas flame temperature reaches a maximum of 1450°C, and the natural gas thermal efficiency utilization rate is approximately 80%. However, existing burners suffer from low thermal efficiency and low calorific value due to insufficient mixing of air and natural gas before combustion.

[0004] Therefore, we propose an energy-saving burner to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an energy-saving burner.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An energy-saving burner comprises a central oxygen pipe, a gas pipe and an inlet for combustion-supporting air, wherein the central oxygen pipe extends from the inlet end of the gas pipe to the gas distributor, the gas pipe penetrates into the combustion-supporting air pipe through the combustion-supporting oxygen pipe, the side of one end of the gas pipe is connected to the gas pipe inlet, and the other end of the gas pipe is connected to the gas distributor, the side of one end of the combustion-supporting oxygen pipe is connected to the inlet of the combustion-supporting oxygen pipe, and the other end of the combustion-supporting oxygen pipe is connected to the combustion-supporting oxygen distributor, a flame stabilizer is provided at the outlet end of the gas pipe, and a gas distributor is provided at the center of the flame stabilizer.

[0008] Preferably, the central oxygen pipe is located at the center of the fuel gas pipe.

[0009] Preferably, the fuel gas pipe passes through the center of the combustion-supporting oxygen pipe.

[0010] Preferably, the combustion-supporting oxygen pipe is connected to the combustion-supporting air pipe through a combustion-supporting oxygen distributor.

[0011] Preferably, a flame stabilizer is provided at the gas distributor.

[0012] Preferably, a fire-resistant heat-insulating layer is provided on the outer layer of the combustion-supporting air pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Pure oxygen gas or oxygen-enriched gas is introduced into the gas distributor through the central oxygen pipe, and then mixed with combustion-supporting air and natural gas. The three form an oxygen-enriched environment for natural gas combustion at the burner outlet and control the oxygen content of the combustion-supporting gas. By establishing an oxygen-enriched combustion environment, the combustion calorific value and efficiency of natural gas are improved, thereby saving the use of natural gas. At the same time, due to the reduction in the proportion of nitrogen in the combustion-supporting gas, nitrogen oxide emissions can be reduced and carbon emissions can be reduced.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4, an energy-saving burner includes a central oxygen pipe 1, a gas pipe 3 and a combustion air inlet 7. The central oxygen pipe 1 extends from the inlet end of the gas pipe 3 to the gas distributor 12. The central oxygen pipe 1 is located at the center of the gas pipe 3. The gas pipe 3 penetrates the combustion air pipe 8 through the combustion oxygen pipe 5. Pure oxygen gas is introduced into the burner through the central oxygen pipe 1. At the same time, pure oxygen gas is introduced into the combustion air pipe 8 through the combustion oxygen pipe 5 to form mixed combustion air. The pure oxygen gas and the mixed combustion air form an oxygen-rich environment for natural gas combustion at the gas distributor 12, and combustion reaction occurs with the natural gas. By establishing an oxygen-rich combustion environment, the combustion calorific value and efficiency of natural gas are improved, achieving the effect of saving natural gas usage. At the same time, due to the reduction in the proportion of nitrogen in the combustion gas, nitrogen oxide emissions can be reduced and carbon emissions can be reduced. The gas pipe 3 passes through the center of the combustion oxygen pipe 5, and the combustion oxygen pipe 5 is connected to the combustion air pipe 8 through the combustion oxygen distributor 6. The outer layer of the combustion air pipe 8 is provided with A refractory insulation layer 9 is provided. Since the entire device is to be extended into the kiln, in order to avoid the influence of the high temperature in the kiln on the combustion-supporting air pipe 8, a refractory insulation layer 9 is provided on the outer layer of the combustion-supporting air pipe, thereby ensuring that the combustion-supporting air pipe does not deform or corrode under high temperature. The side of one end of the gas pipe 3 is connected to the gas pipe inlet 2, and the other end of the gas pipe 3 is connected to the gas distributor 12. The side of one end of the combustion-supporting oxygen pipe 5 is connected to the combustion-supporting oxygen pipe inlet 4. By adjusting the opening of the combustion-supporting oxygen inlet 4 and the combustion-supporting air inlet 7, the combustion-supporting oxygen intake amount and the combustion-supporting air intake amount are adjusted, and the oxygen content of the combustion-supporting gas is controlled to be at an optimal ratio to achieve the optimal combustion calorific value and efficiency, thereby achieving the effect of saving natural gas usage. The other end of the combustion-supporting oxygen pipe 5 is connected to the combustion-supporting oxygen distributor 6, and a flame stabilizer 11 is provided at the outlet end of the gas pipe 3, and a gas distributor 12 is provided at the center of the flame stabilizer 11. A flame stabilizer 11 is provided at the gas distributor 12, which can effectively guide the airflow so that the flame can burn stably.

[0022] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 , oxygen directly reaches the gas distributor 12 from the central oxygen pipe 1, and after mixing with the gas, a combustion reaction occurs. At the same time, oxygen enters the combustion-supporting oxygen pipe 5 through the combustion-supporting oxygen pipe inlet 4, and then enters the combustion-supporting air pipe 8 through the combustion-supporting oxygen distribution pipe 6. After being fully mixed with the combustion-supporting air, it reaches the gas distributor 12 and mixes with the gas to cause a combustion reaction.
