The burner assembly 100 according to the utility model first aspect embodiment is specifically described below in conjunction with accompanying drawing 1 to Fig. 3.
Burner assembly 100 according to the utility model embodiment comprises housing 10, burner 20, blower fan 30 and windsheild 40. specifically, it is limited with in housing 10 and chamber 11 is installed, install in chamber 11 and it is provided with the mounting plate 12 arranged spaced apart with the roof of housing 10, burner 20 is positioned at the top of mounting plate 12 and is connected with mounting plate 12, burner 20 has the first inlet mouth 21 and the 2nd inlet mouth 22, blower fan 30 is located at that housing 10 is outer and the going out air port 31 and install chamber 11 conducting of blower fan 30, go out air port 31 to be oppositely arranged with mounting plate 12, windsheild 40 is located in housing 10 and is positioned at the side of burner 20, outside windsheild 40 projection in the horizontal plane is positioned at air port 31, windsheild 40 is provided with the rib 41 exceeding mounting plate 12 and extending downwards, rib 41 is provided with multiple ventilation hole 411 arranged spaced apart.
In other words, this burner assembly 100 forms primarily of housing 10, burner 20, blower fan 30 and windsheild 40. wherein, housing 10 vertically (upper and lower as shown in Figure 1 to) extend, the installation chamber 11 for install combustion device 20 it is limited with in housing 10, specifically, the mounting plate 12 being provided with in the horizontal direction (direction, left and right as shown in Figure 1) in chamber 11 and extending is installed, and, this mounting plate 12 is arranged spaced apart with diapire and the roof of housing 10, burner 20 is located on the upper surface of this mounting plate 12, it is outer and be positioned at the lower section of housing 10 that blower fan 30 is located at housing 10, the diapire of housing 10 is provided with the open holes going out air port 31 conducting with blower fan 30, and the air port 31 that goes out of blower fan 30 is oppositely arranged with mounting plate 12.
Further, the sidepiece of burner 20 has the first inlet mouth 21 arranged spaced apart and the 2nd inlet mouth 22, windsheild 40 establishes the sidepiece installed in chamber 11 and with burner 20 to be connected, outside windsheild 40 projection in the horizontal plane is positioned at air port 31, specifically, as shown in Figure 3, windsheild 40 is located at the left side of burner 20 and windsheild 40 is positioned at the upper left side in air port 31, the lower end of windsheild 40 is provided with the rib 41 exceeding mounting plate 12 and extending downwards, and this rib 41 is provided with multiple ventilation hole 411 arranged spaced apart.
When this burner assembly 100 is started working, enter install in chamber 11 from air port 31 air out that goes out of blower fan 30, portion of air is blown and is spread to rib 41 after mounting plate 12, then pass from the ventilation hole 411 rib 41, enter in burner 20 by the first inlet mouth 21 and the 2nd inlet mouth 22, portion of air avoids rib 41, detour in bottom from rib 41 enters using the primary air as combustion gas mixing in burner 20, and another part air directly enters in burner 20 from the through hole mounting plate 12 using the secondary air as combustion gas mixing.
Thus, burner assembly 100 according to the utility model embodiment, by arranging at the sidepiece of burner 20, there is the windsheild 40 exceeding the rib 41 that mounting plate 12 extends downwards, and on rib 41, it is provided with multiple ventilation hole 411 arranged spaced apart, the effect regulating the air capacity needed for burner 20 can be played, effectively control distribution of air flow, make the air distribution to burner 20 diffusion even, the phenomenon affecting the stable burning of combustion gas because air inlet is uneven is avoided to occur, reach the object of discharged nitrous oxides in control flue gas, the structure of this burner assembly 100 is simple, compact, flameholding, performance is good.
Wherein, according to an embodiment of the present utility model, windsheild 40 is connected with burner 20, and windsheild 40 has the first ventage 42 and the 2nd ventage 43 that are connected with the first inlet mouth 21 with the 2nd inlet mouth 22.
That is, windsheild 40 has the first ventage 42 and the 2nd ventage 43, wherein, the first inlet mouth 21 conducting of the first ventage 42 and burner 20, the 2nd inlet mouth 22 conducting of the 2nd ventage 43 and burner 20. Specifically, as depicted in figs. 1 and 2, the sidepiece of burner 20 is provided with multiple first inlet mouth 21 arranged spaced apart and multiple 2nd inlet mouth 22 arranged spaced apart, and windsheild 40 is provided with multiple along its length the first ventage 42 that (direction, left and right as shown in Figure 1) is arranged spaced apart and multiple 2nd ventage 43 arranged spaced apart along its length, the position one_to_one corresponding of multiple first inlet mouth 21 and multiple first ventage 42, multiple 2nd inlet mouth 22 and multiple 2nd ventage 43.
Preferably, according to an embodiment of the present utility model, windsheild 40 and rib 41 extend respectively along the vertical direction. Specifically, as shown in Figure 3, windsheild 40 and rib 41 are formed as vertically the plate body that (upper and lower as shown in Figure 3 to) extends respectively, wherein, windsheild 40 is connected with the sidepiece of burner 20 so that the first ventage 42 of windsheild 40 is connected with the 2nd inlet mouth 22 with the first inlet mouth 21 of burner 20 respectively with the 2nd ventage 43, and rib 41 is located at the lower section of mounting plate 12 and the upper end of rib 41 is connected with the lower end of windsheild 40.
Thus, this rib 41 can hinder the air produced by boasting from blower fan 30 directly to enter in burner 20, but enter in burner 20 by the multiple ventilation holes 411 on rib 41, play the effect regulating the air capacity needed for burner 20, effectively control distribution of air flow, make the air distribution to burner 20 diffusion even, avoid the phenomenon affecting the stable burning of combustion gas because air inlet is uneven to occur, reach the object of discharged nitrous oxides in control flue gas.
Further, the distance that the length that rib 41 extends downwards is less than between the diapire of mounting plate 12 and housing 10. in other words, rib 41 upper and lower to the length distance that is less than between the diapire of mounting plate 12 and housing 10, when this burner assembly 100 is started working, enter install in chamber 11 from air port 31 air out that goes out of blower fan 30, portion of air is blown and is spread to rib 41 after mounting plate 12, owing to being subject to the stop of rib 41, air along rib 41 length direction diffusion and pass from the ventilation hole 411 rib 41, enter in burner 20 by the first inlet mouth 21 and the 2nd inlet mouth 22, portion of air avoids rib 41, detour from the bottom of rib 41, enter in burner 20 using the primary air as combustion gas mixing.
Therefore, this rib 41 both can play the effect regulating the air capacity needed for burner 20, effectively control distribution of air flow, make the air distribution to burner 20 diffusion even, the phenomenon affecting the stable burning of combustion gas because air inlet is uneven is avoided to occur, can ensure that again air input is sufficient, reach the object of discharged nitrous oxides in control flue gas.
Wherein, according to an embodiment of the present utility model, multiple ventilation hole 411 one-tenth many rows multiple row is arranged. Can make to spread air to rib 41 like this to pass from the ventilation hole 411 rib 41, enter in burner 20, the effect regulating the air capacity needed for burner 20 can be played better, more effectively control distribution of air flow, make the air distribution to burner 20 diffusion even, avoid the phenomenon affecting the stable burning of combustion gas because air inlet is uneven to occur, reach the object of discharged nitrous oxides in control flue gas.
