This application proposes a fire exhaust.

In an embodiment of the present application, as shown in Figures 1 to 7, the fire row includes:

The fire exhaust body 100 has a main air passage 110 formed in the fire exhaust body 100.

The communication port 130 communicates with the main airway 110; and

The flame stabilizing member 200 is provided outside the fire exhaust body 100 and is jointly constructed with the flame exhaust body 100 to form an auxiliary air channel 201. The auxiliary air channel 201 is connected to the communication port 130. The flame stabilizing member The top of 200 is also provided with an auxiliary air outlet 202 connected with the auxiliary airway 201 .

The inventor found that the core component of the gas water heater is equipped with a fire exhaust in the burner. However, in the prior art, the combustion intensity of the fire exhaust at the position of the fire hole is high, and the performance of the smoke emitted by instantaneous combustion is poor, resulting in higher nitrogen oxides. high. In the technical solution of the present application, a flame stabilizing member 200 is added to the outside of the fire exhaust body 100 to add an auxiliary air channel 201 on the outside of the fire exhaust body 100. The auxiliary air channel 201 passes through the communication port 130 on the side of the fire exhaust body 100 and The main air channels 110 are connected, and the main air outlet 120 of the main air channel 110 and the auxiliary air outlet 202 of the auxiliary air channel 201 together form the fire hole of the fire row. After the air flow is delivered to the main air channel 110, part of the air flow will enter the auxiliary air channel 201 through the connecting port 130, and the air flow will be divided through the auxiliary air channel 201 to reduce the air output of the main air outlet 120, thereby reducing the combustion of the main air outlet. strength. The auxiliary air outlet 202 of the auxiliary air duct 201 is equivalent to increasing the fire hole area of the fire exhaust, and the combustion intensity of the fire exhaust is reduced, which is conducive to ensuring that the air flow is sufficient in the fire holes, thereby improving the performance of the smoke emitted by instantaneous combustion. , reducing nitrogen oxides produced by combustion.

Further, in this embodiment, the flame stabilizing member 200 includes two first connecting portions 210 that are oppositely arranged and connected to the fire exhaust body 100. The opposite sides of the fire exhaust body 100 are provided with certain The communication port 130, a first connection part 210 is formed with an auxiliary air passage 201 corresponding to one side of the fire exhaust body 100, and the top of the first connection part 210 is formed with a connection with the corresponding The auxiliary air outlet 202 of the auxiliary airway 201.

Moreover, multiple communication ports 130 are spaced apart. Allowing the air flow to flow dispersedly from the main air channel 110 to the auxiliary air channel 201 can slow down the air outlet flow rate of the main air outlet 120 and the auxiliary air outlet 202, which is beneficial to the complete combustion of the air flow. Of course, in other embodiments, the communication port 130 may also be provided in a strip shape extending along the length direction of the fire row body 100 .

Complete combustion in the fire hole, thereby further improving the performance of smoke emitted by instantaneous combustion and reducing the nitrogen oxides produced by combustion. Furthermore, the plurality of partitions 140 are evenly spaced on the top of the fire exhaust body 100, which can further improve the uniformity of flame distribution in the main air outlet. In addition, the second connection part 220 is connected to the partition part 140, which can prevent the second connection part 220 from interfering with the air outflow from the main air outlet 120, thereby ensuring full combustion of the air flow.

At the same time, the arrangement of multiple second flame holes 122 can further improve the uniformity of the flame.

Further, in this embodiment, as shown in Figures 2 to 7, the fire row also includes a combustion panel 300. The combustion panel 300 is configured as a metal mesh structure, and the combustion panel 300 is fixedly connected to the partition. Department 140. The combustion panel 300 with a metal mesh structure can increase the heat load of the fire exhaust, improve its adaptability range, and then achieve better instantaneous combustion and smoke emission performance, and finally achieve lower nitrogen oxides produced after combustion. At the same time, considering that the temperature of the combustion place is very high when the fuel is burned, in order to ensure the life of the combustion panel 300, the multi-layer metal mesh needs to be a high-temperature resistant material. Of course, in other embodiments, the combustion panel 300 may not be provided, and the airflow may directly burn at the first fire hole 121 and the second fire hole 122 of the fire exhaust body 100 .

Furthermore, as shown in Figures 2 to 4, the combustion panel 300 is configured as a multi-layer metal mesh structure. When the opening area of the metal mesh is large, the multi-layer metal mesh structure can prevent burner explosion caused by backfire. Accident, among which, the number of layers of the metal mesh is related to the mesh number of the multi-layer metal mesh. The number of mesh layers in the multi-layer metal mesh is negatively correlated with the mesh number, that is, the corresponding number of layers of the metal mesh with a large mesh number. For example, the number of layers of a multi-layer metal mesh includes but is not limited to 2 to 10 layers. Specifically, it can be 2 layers, 3 layers, 5 layers, 8 layers, or 10 layers. Commonly used metal meshes range from 20 mesh to 100 mesh, specifically 20 mesh, 40 mesh, 50 mesh, 60 mesh, 80 mesh or 100 mesh. Considering that too many layers may lead to insufficient air flow supply, And the metal mesh with larger mesh is expensive. After testing and research, the combination of multi-layer metal mesh is 50 mesh and 3 layers. Since the combustion panel 300 has a multi-layer metal mesh structure, the area of the main air outlet 120 is enlarged, resulting in better instantaneous combustion and smoke emission performance, and can reduce the generation of nitrogen oxides. At the same time, the combustion panel 300 also has flame stabilization properties. Function, it can increase the thermal load combustion adaptability range of the fire exhaust body 100, which can solve the problem of low load use and reduce segmentation. It has a simple structure, easy manufacturing, low cost, and can meet the low nitrogen requirements of the whole machine. Emission usage requirements.

During the production and processing of the combustion panel 300, a single piece of metal mesh can be bent multiple times to form the combustion panel 300 with a multi-layer metal mesh structure. In this way, the processing and shaping of the combustion panel 300 can be facilitated, thereby improving the production efficiency of the combustion panel 300 .

In one embodiment, as shown in FIG. 3 , the combustion panel 300 includes a stack of multiple layers of metal mesh, and a buffer cavity 310 is formed between each two adjacent layers of metal mesh. Specifically, among the two adjacent layers of metal mesh, the edges of the opposite ends of at least one layer of metal mesh are bent to form bending portions. Tension will be generated at the bending portion, and the strength of the bent metal mesh will be higher. Here, the folds can be on both sides in the width direction or on both sides in the length direction. From the perspective of effect, the bending tension at both ends of the length direction of the metal mesh is greater, and the corresponding strength of the metal mesh is also higher. big. Secondly, connecting the bending part with the bending part or the metal mesh of another layer can form a buffer cavity 310 between the two adjacent layers of metal mesh. This arrangement can play a role in slowing down the air flow to ensure that The main air outlet 120 has sufficient air flow supply.

The fire exhaust body 100 and the combustion panel 300 are welded on the outside of the body 100. The second connection part 220 and the partition part 140 are also spot welded at the welding action part 150, and the bottom of the first connection part 210 is connected with the fire The sides of the row body 100 are connected by spot welding.
