The combustion assembly and its stabilizer plate of the present utility model are described below in conjunction with fig. 1-14. It will be appreciated that the fire cover, also known as the distributor, is the part of the burner where the upper end temperature is highest. The fire cover is provided with a fire hole, and the fuel gas is mixed with air at the fire hole and burnt.

It can be understood that during the combustion process, the flow rate of the fuel gas affects the stability and combustion effect of the flame, the gas flow rate directly relates to the mixing ratio of the fuel and the oxygen, when the mixing ratio of the fuel and the oxygen is low, sufficient fuel and oxygen cannot be provided, so that the flame is weakened or even extinguished, and a large amount of harmful gas such as carbon monoxide can be generated due to incomplete combustion; when the gas flow is too large, the mixing ratio of the fuel and the oxygen is too high, which causes too large flame and overheating, and the too high gas flow also increases the waste of energy and may cause overheating or damage of equipment.

Referring to fig. 2 and 4, a combustion assembly 100 according to an embodiment of the present utility model includes a flame cover 120 and a stabilizer plate 110.

Specifically, the gas chamber 124 is provided in the flame cover 120, and the gas flows through the gas chamber 124. The flame stabilizing groove 125 and the plurality of flame outlets 126 are arranged on the flame cover 120, the gas chamber 124 is communicated with the outside through the flame outlets 126 and the flame stabilizing groove 125, and the gas and the air are mixed through the flame outlets 126 and the flame stabilizing groove 125, and the mixed gas is burnt at the flame outlets 126 and the flame stabilizing groove 125. The flame stabilizing groove 125 can play a role in pressure relief, reduce the flow velocity of the fuel gas at the flame outlet 126, and avoid the adverse conditions such as flame separation and the like caused by the fact that the fuel gas leaves the burner too quickly.

The stabilizer plate 110 is disposed in the gas chamber 124, and the stabilizer plate 110 is detachably connected to the fire cover 120, so that the stabilizer plate 110 can be replaced. For example, the stabilizer 110 may be fastened to the fire cover 120 by a buckle, or the stabilizer 110 may be embedded to the fire cover 120 by elastic deformation. The flow stabilizer 110 is provided with a plurality of flow limiting holes 113, and the flow rate of the fuel gas flowing to the flame outlet 126 or the flame stabilizing groove 125 is controlled by the flow limiting holes 113, and at least one of the flow limiting holes 113 is communicated with the flame stabilizing groove 125.

As shown in fig. 2, the flow stabilizing plate 110 is provided with two rows of flow limiting holes 113, wherein one row of flow limiting holes 113 is communicated with the flame stabilizing groove 125, and the other row of flow limiting holes 113 is communicated with the fire outlet hole 126 so as to control the flow rate of the fuel gas flowing to the fire outlet hole 126 and the flame stabilizing groove 125, thereby controlling the flow rate of the fuel gas at the fire outlet hole 126 and the flame stabilizing groove 125, avoiding the occurrence of the fire-off phenomenon in the combustion process and improving the combustion stability. Meanwhile, the depth of the flame stabilizing groove 125 or the flame outlet 126 can be increased by the flow limiting hole 113 to provide more stable combustion areas, so that the flame is easier to maintain in a stable state, and a space for the flame to flow back can be provided during flameout, so that the flame is prevented from being transmitted into a gas chamber, the possibility of backfire during flameout is reduced, and flameout noise is reduced.

According to the combustion assembly 100 of the embodiment of the utility model, the flow rate of the fuel gas flowing to the flame stabilizing groove 125 and the flame outlet hole 126 is controlled by arranging the flow stabilizing plate 110 in the fuel gas chamber 124, so that the phenomenon of flame failure in the combustion process is avoided, and the combustion stability is improved. Meanwhile, the flow limiting hole 113 may increase the depth of the flame stabilizing groove 125 or the flame exit hole 126, may reduce the probability of flashback occurring at the time of flameout, and may reduce flameout noise.

Referring to fig. 7 and 11, a stabilizer plate 110 for a combustion assembly 100 according to an embodiment of the present utility model is shown, and the stabilizer plate 110 is applied to the combustion assembly 100 described above. The stabilizer 110 includes a first stabilizer 111 and a second stabilizer 112.

Specifically, the second stabilizer 112 is connected to the first stabilizer 111, and at least one of the second stabilizer 112 and the first stabilizer 111 is adapted to be connected to the fire cover 120. That is, the stabilizer plate 110 may be mounted to the flame cover 120 through the first stabilizer 111 or the second stabilizer 112, or may be mounted to the flame cover 120 through the first stabilizer 111 and the second stabilizer 112. For example, in the example of fig. 4, the first stabilizer 111 is attached to the fire cover 120 and connected to the fire cover 120.

At least one of the second flow stabilizer 112 and the first flow stabilizer 111 is provided with a plurality of flow limiting holes 113, and the flow limiting holes 113 are used for controlling the flow of the fuel gas. In the example of fig. 7, a plurality of flow limiting holes 113 are formed on each of the first flow stabilizing portion 111 and the second flow stabilizing portion 112; in the example of fig. 11, the first flow stabilizer 111 is provided with a plurality of flow limiting holes 113, and the second flow stabilizer 112 may not be provided with the flow limiting holes 113. The flow rate of the fuel gas in the fire cover 120 is controlled through the flow limiting holes 113 on the flow stabilizing plate 110, so that the flow rate of the fuel gas is controlled, the fuel gas is stably provided in the combustion process, and the combustion process is more stable.

According to the stabilizer plate 110 of the embodiment of the utility model, the flow rate of the fuel gas is controlled by controlling the flow rate of the fuel gas in the fire cover 120 through the stabilizer plate 110, so that the fuel gas is stably provided in the combustion process, and the combustion process is more stable.

Referring to fig. 3 and 5, according to some embodiments of the present utility model, the flame holding grooves 125 are plural, the flame holding grooves 125 are spaced apart in the circumferential direction of the flame cover 120, and the flame holding grooves 125 divide the flame cover 120 into upper and lower parts. Any two adjacent flame holding grooves 125 are separated by a connecting portion 1251, and the connecting portion 1251 is used for connecting the upper portion and the lower portion of the fire cover 120. As shown in fig. 3, the plurality of flame outlets 126 are spaced apart along the circumferential direction of the fire cover 120, and the flame stabilizing slots 125 are located below the flame outlets 126 (in the direction shown in fig. 3), so that when a flame is lifted, the flame stabilizing slots 125 can ignite the gas flowing out of the flame outlets 126 from the root, thereby re-burning the gas and forming a stable flame to improve the stability of the flame. On the premise of ensuring the structural strength of the fire cover 120, the smaller the volume of the connecting part 1251 is, the better the number of the fire outlets 126 corresponding to the flame stabilizing grooves 125 is, and the flame stabilizing effect is improved.

In the example of fig. 5, the gas flows from the inside of the gas chamber 124 to the outside of the flame cover 120, and is ignited at the flame holding groove 125 and the flame exit hole 126, and the flame is ejected in a direction away from the flame cover 120 in the radial direction of the flame cover 120. In the direction in which the flame is ejected, the cross-sectional area of the connection portion 1251 gradually decreases, for example, in the example of fig. 5, the cross-section of the connection portion 1251 is triangular, and one apex angle of the triangle faces the ejection direction of the flame. Thus, the length of the part of the flame stabilizing groove 125 on the outer surface of the fire cover 120 can be increased, the flame stabilizing groove 125 can correspond to more flame outlets 126, and the flame stabilizing effect is improved.

Referring to fig. 1 and 3, according to some embodiments of the present utility model, the flame holes 126 include a plurality of main flame holes 1261 and a plurality of auxiliary flame holes 1262, the plurality of main flame holes 1261 and the plurality of auxiliary flame holes 1262 are all distributed at intervals along the circumferential direction of the flame cover 120, and the auxiliary flame holes 1262 are located between the main flame holes 1261 and the flame holding groove 125. In the example of fig. 3, two rows of fire holes 126 are provided on the fire cover 120, one row of primary fire holes 1261 and the other row of secondary fire holes 1262, and the primary fire holes 1261 and the secondary fire holes 1262 are located above the flame holding grooves 125 (in the direction shown in fig. 3), and the vertical distance between each primary fire hole 1261 and each secondary fire hole 125 is greater than the vertical distance between each secondary fire hole 1262 and each flame holding groove 125, that is, the primary fire holes 1261 are located above the secondary fire holes 1262. On the one hand, the auxiliary fire hole 1262 can play a role in pressure relief, so that the flow rate of the fuel gas is kept stable, and the stability of flame is improved; on the other hand, the auxiliary fire hole 1262 is located below the main fire hole 1261, so that the gas flowing out of the main fire hole 1261 can be ignited from the root, and the combustion is more sufficient.

In some embodiments, the secondary fire holes 1262 and the primary fire holes 1261 are staggered. For example, in the example of fig. 3, one auxiliary fire hole 1262 is provided below a position between two adjacent main fire holes 1261, so that flames ejected from the auxiliary fire holes 1262 can fill gaps between flames ejected from the main fire holes 1261, and the area of the whole flames is increased, thereby increasing the heating speed. The secondary fire hole 1262 and the primary fire hole 1261 may each be circular, and the diameter of the secondary fire hole 1262 may be smaller than the diameter of the primary fire hole 1261.

Referring to fig. 4, according to some embodiments of the present utility model, the fire cover 120 includes a first sidewall 121, a second sidewall 122, and a third sidewall 123 connected in sequence, the first sidewall 121 and the third sidewall 123 being opposite. The first, second and third side walls 121, 122, 123 define a gas chamber 124 having an annular shape, wherein the first side wall 121 is an inner ring and the third side wall 123 is an outer ring. In some embodiments, the side of the third sidewall 123 that connects with the second sidewall 122 is higher than the side of the first sidewall 121 that connects with the second sidewall 122, and the second sidewall 122 has a tendency to extend downward (as shown in the direction of fig. 4) in the direction from the outer ring to the inner ring.

The flame stabilizing groove 125 is disposed on the third sidewall 123, and the flame stabilizing groove 125 extends along the circumference of the fire cover 120. The flame outlets 126 are disposed on the third sidewall 123, and the plurality of flame outlets 126 are spaced apart along the circumference of the flame cover 120, where the flame outlets 126 are closer to the second sidewall 122 than the flame stabilizing slots 125, that is, the flame stabilizing slots 125 are located below the flame outlets 126 (in the direction shown in fig. 4), so as to improve the stability of the flame sprayed from the flame outlets 126. It will be appreciated that the fire hole 126 is directed upward (as shown in fig. 4) from the inner wall of the third side wall 123 to the outer wall thereof, thereby reducing the contact area of the flame with the fire cover 120, to prevent the flame from burning the fire cover 120 for a long time, and to extend the service life of the fire cover 120.

Referring to fig. 1, the second side wall 122 is provided with a fire transfer groove 1221 and a fire transfer hole 1222, one end of the fire transfer groove 1221 is communicated with one of the fire outlet holes 126, the fire transfer groove 1221 extends in the radial direction of the annular gas chamber 124, and the fire transfer hole 1222 is located at the other end of the fire transfer groove 1221. The flame propagation grooves 1221 and the flame propagation holes 1222 are used for igniting the fuel gas, and the fuel gas is ignited from one end close to the inner ring during ignition, and the fuel gas at the flame holes 126 and the flame stabilizing grooves 125 is ignited through the flame propagation grooves 1221 and the flame propagation holes 1222, so as to avoid the explosion caused by the ignition of excessive fuel gas during ignition. The fire holes 1222 may be plural.

Referring to fig. 11, according to some embodiments of the present utility model, the first stabilizer 111 is provided with a plurality of flow limiting holes 113, the plurality of flow limiting holes 113 are spaced along the extending direction of the first stabilizer 111, and the flow limiting holes 113 are adapted to communicate with the flame stabilizing slots 125 to limit the flow rate of the fuel gas flowing to the flame stabilizing slots 125. Of course, in some embodiments, a plurality of flow limiting holes 113 may be disposed on the second flow stabilizer 112, and the plurality of flow limiting holes 113 are spaced apart along the extending direction of the second flow stabilizer 112.

The plurality of flow restricting holes 113 may be uniformly distributed, or the interval between adjacent two flow restricting holes 113 may be gradually reduced in the extending direction of the first flow stabilizing part 111 or the second flow stabilizing part 112. It can be understood that, when the first flow stabilizing portion 111 or the second flow stabilizing portion 112 is annular, the extending direction is an annular circumferential direction; when the first flow stabilizing portion 111 or the second flow stabilizing portion 112 is rectangular, the extending direction is the rectangular length direction.

As shown in fig. 2, the first flow stabilizing portion 111 and the second flow stabilizing portion 112 extend circumferentially along the inner wall of the fire cover 120, so that the first flow stabilizing portion 111 or the second flow stabilizing portion 112 may be attached to the inner wall of the fire cover 120, the flow limiting hole 113 on the first flow stabilizing portion 111 corresponds to the flame stabilizing slot 125, and the flow limiting hole 113 on the second flow stabilizing portion 112 corresponds to the flame outlet hole 126. As shown in fig. 4, the first flow stabilizer 111 shields the flame stabilizing groove 125, and the flow limiting hole 113 on the second flow stabilizer 112 is communicated with the flame stabilizing groove 125. On the one hand, the flow rate of the fuel gas flowing to the flame outlet hole 126 and the flame stabilizing groove 125 can be controlled by the flow limiting hole 113 to control the flow rate of the fuel gas, thereby improving the stability of the flame; on the other hand, the distance from the outer peripheral wall of the fire cover 120 to the gas chamber 124 is increased by the flow limiting hole 113, the depths of the fire outlet hole 126 and the flame stabilizing groove 125 are increased, and when the flame is extinguished, the flame passes into the fire outlet hole 126 or the flame stabilizing groove 125 and is extinguished because the fuel gas is consumed, so that the flame is prevented from passing into the gas chamber 124, the occurrence of backfire is avoided, and the flameout noise is reduced.
