Description

Fire row piece, burner and water heater for burner

Technical field

This application involves technical field of burner, more particularly to can reduce burning in generate nitrogen oxides fire row piece, Burner and water heater.

Background technique

In order to which the discharged nitrous oxides to fast gas heater control, a kind of deep or light combustion is proposed in the prior art The concept of burning is specifically exactly that fuel supply is divided into two strands in burning, the primary air (fresh air) of one fuel Coefficient is less than 1.0, i.e., with the work of dense combustion system；In addition the primary air ratio of one fuel is greater than 1.0, i.e., with light burning side Formula work.The deep or light mode for intersecting burning reduces temperature when burning, so that the low nitrogen oxygen of heating power type generated in burning The content sharp fall of compound, to achieve the purpose that emission reduction.

However, if the combustion gas flow direction inside fire row piece cannot be controlled preferably, being easy to make when using bias combustion method Fire row piece burning-flame port at air pressure occur it is unbalanced, simultaneously because the fuel gas flow for burning is unstable, be easy to happen example Such as flame jump even detonation dangerous situation.Applicant have observed that the outlet pore morphology being responsible on the ejector pipe of dense burning with And the airflow channel form of fire row piece body interior all can generate large effect to the stability of fuel gas flow.

In order to be further understood that the feature and technology contents of the application, please refer to below in connection with the detailed of the application Illustrate and attached drawing, however, the drawings only provide reference and explanation, is not used to limit the application.

Detailed description of the invention

The aforementioned and other aspects of the application will more completely be managed and that is done with reference to the accompanying drawings is discussed in detail Solution and understanding, in the accompanying drawings:

Figure 1A shows the fire row piece main part of one specific embodiment of the application；

Figure 1B shows first ejector pipe and the second injection tube portion of one specific embodiment of the application；

Fig. 2 is the schematic top plan view of fire row piece body top.

Specific embodiment

For help those skilled in the art definitely understand this application claims theme, with reference to the accompanying drawing in detail The specific embodiment of the application is described.

Referring to the fractionation schematic diagram for a specific embodiment for shown in Figure 1A and Figure 1B, showing the application.Wherein, scheme 1A main presentation fire row piece main part, the first ejector pipe of Figure 1B main presentation and the second injection tube portion.In the specific implementation In mode, the fire row piece of the application includes:

The fire row piece main body 1 surrounded by two side wall panels 10；First burning at 1 top 20 of fire row piece main body is set Hungry ghosts who spit fire 21 and the second burning-flame port 22；It is at least partially disposed in 1 inside of the fire row piece main body and its tube wall and the two sidewalls The first ejector pipe 30 of the interlayer (not shown) passed through for air-flow is formed between plate 10, tube wall offers generally rectangular Outgassing groove 31, the interlayer is connected to first burning-flame port, and the surface of two side wall panels 10 is stamped to form oriented interlayer side To the air flow partition area 50 of recess；The lower section of first ejector pipe 30 is additionally provided be directly connected to second port 22 Two ejector pipes 40.

In this embodiment, the outer profile in the air flow partition area 50 is configured to generally arcuate, internal tool There are three the airflow channels 51 for allowing air-flow to pass through.As shown, the longitudinal section of these airflow channels 51 is substantially trapezoidal or loudspeaker Shape, each airflow channel 51 has the first end 51a positioned at the arch string side and second end 51b positioned at arcuate arc side, described The opening of first end 51a is greater than the opening of the second end 51b.As preferable embodiment, the opening of the first end 51a Width is 3.3mm, and the opening width of second end 51b is 2.3mm.The fuel-air introduced by the arrival end 32 of the first ejector pipe 30 Mixed airflow escapes into interlayer from outgassing groove 31, by interlayer upwards until the first burning-flame port 21 for reaching top surface participates in combustion It burns.When mixed airflow passes through air flow partition area 50, mixed airflow have to from the airflow channel 51 in air flow partition area 50 and The two sides in air flow partition area 50 pass through.The mixed gas escaped as a result, from outgassing groove 31 makes to reach on the way by uniform divided flows The gaseous mixture air-flow more even of first burning-flame port 21.

In other embodiments, the air flow partition area 50 can also be not provided with the channel 51 for allowing air-flow to pass through.Class As, it is escaped into interlayer, is led to from outgassing groove 31 by the fuel-air mixture stream that the arrival end 32 of the first ejector pipe 30 is introduced into The first burning-flame port 21 that interlayer is crossed up to top surface participates in burning.When these mixed airflows pass through gas during upwards When flowing exclusion region 50, it is forced the position where getting around air flow partition area 50 and also can so as to adjust flow direction, the change of this flow direction The partial pressure in interlayer is influenced, the consistent level of mixed airflow at burning-flame port 21 is thus better balanced, reaches stable The purpose of burning.

In this embodiment, 31 length of outgassing groove of first ejector pipe 30 is 16mm, width 2mm.With The advantages of multiple small sircle hole shape outgassing grooves are compared, are similar to rectangular outgassing groove 31 in the prior art is that interlayer can be reduced The vortex of the generation of middle airflow channel, to reduce the resistance of airflow channel.

The quantity of first burning-flame port 21 and second burning-flame port 22 be it is multiple and be bar shaped, each first, It is parallel to each other between second burning-flame port 21,22.It is shown in Figure 2, when from perpendicular to the direction at the top of the fire row piece main body 1 When observation, first burning-flame port 21 is located at the two sides at 1 top of fire row piece main body, and second burning-flame port 22 is located at The centre at 1 top of fire row piece main body.Wherein, dense burning carries out in the first burning-flame port 21, and light burning is in the second burning It is carried out in hungry ghosts who spit fire 22.Application about dense-dilute burner combustion technology in fire row piece field has been well known to those skilled in the art, herein It repeats no more.

Disclosed herein as well is a kind of burners, including multiple aforementioned fire row pieces arranged side by side.The application is open simultaneously A kind of water heater, using burner above-mentioned.It is understood that the burner and water heater using aforementioned fire row piece can also To realize beneficial effect cited by the application.

Although having been shown and described the application based on specific embodiment, the application is not restricted to shown thin Section.On the contrary, the various details of the application can be modified in the range of claim and its equivalent replacement.
