The flame stabilizing member The top of 200 is also provided with an auxiliary air outlet 202 connected with the auxiliary airway 201 .
发明人发现,燃气热水器的核心部件,燃烧器内设置有火排,但是现有技术中火排在火孔位置的燃烧强度大,瞬间燃烧所排放的烟气性能不好,导致氮氧化物较高。在本申请技术方案中,火排本体100的外侧增设有稳焰件200,以在火排本体100的外侧增加副气道201,副气道201通过火排本体100侧部的连通口130与主气道110相连通,主气道110的主出气口120和副气道201的副出气口202共同组成火排的火孔。向主气道110输送气流后,部分气流将通过连通口130进入副气道201,通过副气道201对气流进行分流,以减少主出气口120的出气量,从而减小了主气口的燃烧强度。而副气道201的副出气口202相当于增加了火排的火孔面积,火排的燃烧强度得以降低,有利于保障气流于火孔充分的程度,从而能够提升瞬间燃烧排放的烟气性能,降低燃烧产生的氮氧化物。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.
进一步地,在本实施例中,所述稳焰件200包括相对设置并连接于所述火排本体100的两第一连接部210,所述火排本体100的相对两侧部均设置有所述连通口130,一所述第一连接部210对应与所述火排本体100的一侧部构造形成有一所述副气道201,且所述第一连接部210的顶部形成有连通于对应的所述副气道201的所述副出气口202。如此,能够进一步降低主出气口120的出气量以及增加火排的火孔面积,以进一步降低火排的燃烧强度,有利于保障气流在火孔充分燃烧,从而进一步提升瞬间燃烧排放的烟气性能,降低燃烧产生的氮氧化物。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. In this way, the air output of the main air outlet 120 can be further reduced and the fire hole area of the fire exhaust can be further reduced to further reduce the combustion intensity of the fire exhaust, which is beneficial to ensuring that the air flow is fully burned in the fire holes, thereby further improving the performance of instantaneous combustion emissions of smoke. , reducing nitrogen oxides produced by combustion.
进一步地,在本实施例中,所述火排本体100的侧部设置有多个所述连通口130,多个所述连通口130在所述火排本体100的长度方向上间隔分布,所述副气道201对应沿所述火排本体100的长度方向延伸。如此,连通口130的流通面积得以增加,能够提升气流自主气道110向副气道201的流通效率,有利于提升副气道201对气流的分流作用,并且,多个连通口130间隔分布,使得气流分散地自主气道110向副气道201流通,能够减缓主出气口120和副出气口202的出气流速,有利于气流的充分燃烧。当然,在其他实施例中,也可以是,连通口130设置为沿火排本体100的长度方向延伸的长条形。Further, in this embodiment, a plurality of the communication openings 130 are provided on the side of the fire exhaust body 100, and the plurality of communication openings 130 are spaced apart in the length direction of the fire exhaust body 100, so The auxiliary air passage 201 extends along the length direction of the fire exhaust body 100 .

The two rectifying racks 230 will be distributed on opposite sides of the fire hole along the width direction of the fire row. When the airflow flows through the sides of the fire row in the width direction, the airflow will flow out from the tooth grooves of the rectifying rack 230. It can reduce the flow speed of the air flow and avoid the generation of eddy current. Therefore, the fire exhaust of the present application can rectify the airflow on its side through the rectifying rack 230 provided on it to ensure the working performance of the burner. Moreover, the rectifying rack 230 is arranged on the outer side of the flame stabilizing member 200 , will not affect the air outlet of the auxiliary air outlet 202.
