Abstract

PURPOSE:To achieve in a combustion apparatus for domestic use a reduction of NOx in the emission, adaptability for various kinds of gases, reduction of the noise of combustion, and enlargement of the controllability range in the amount of combustion. CONSTITUTION:There are provided a first fuel-air mixture chamber 3 formed in a burner which has a first flame-hole part 1, a second fuel-air mixture chamber 5 having a second flame-hole part 4 which is formed adjacently to the first fuel-air mixture chamber 3, a passage 6 for fuel-air mixture opened through the first fuel-air mixture chamber 3 and the second fuel-air mixture chamber 5, and an air intake 24 formed at the second fuel-air mixture chamber 5; an inlet 13 inside the first fuel-air mixture chamber 3, through which fuel-air mixture is fed to the first flame-hole part 1, is formed on the upstream side of the passage 6 for fuel-air mixture. Fuel-air mixture, whose directional tendency to flow upward makes it difficult to be released sideways, is released through the passage 6 for fuel-air mixture in larger quantities than though the inlet 13 so that, as compared with conventional practices, the amount of combustion of a thin flame produced at the second flame-hole part 4 can be made larger than the amount of combustion of a concentrated flame produced at the first flame-hole part 1 and most of fuel can be burnt in a thin flame produced at a lower temperature at the second flame-hole part 4. Thus an apparatus can perform combustion both in a concentrated state and in a thin state simultaneously and with a decrease in the NOx in the emission.

[0003] In the combustion apparatus having the above structure, a stable rich flame with a low oxygen concentration is formed above the first flame port 1. In addition, a large amount of air from the air intake port 8 and the mixture supplied from the mixture passage 6 become a lean mixture outside the flammable limit inside the second mixture chamber 5, and flow out from the second flame port 4. The fuel burned under the thermal influence of the rich flame, forming a lean flame with a high oxygen concentration. An attempt was made to stabilize a lean flame, which has unstable characteristics due to its low NOx concentration, with a rich flame, thereby realizing concentrated combustion as a whole and reducing the generation of NOx.

In the above configuration, part of the combustion air supplied from the fan 28 flows into the burner body lower part 11 from the throat part 25, and most of the remaining air flows between the burner bodies, that is, the air intake part. 24 and is supplied to the respective second mixture chambers 5. On the other hand, the fuel supplied from the fuel pipe 27 is ejected from each nozzle 26 toward each throat portion 25, flows into the interior of the lower part 11 of the burner body, mixes, and is supplied to the first mixture chamber 3.

Next, the combustion principle of this burner will be explained. The mixture inside the first mixture chamber 3 has a primary air ratio of 3.
It is set from 0 to 60%. A part of this mixture is ejected from the first flame port 1 and the flame-holding mixture passage 16 to form a rich flame, and most of the remaining mixture is sent from the mixture passage 6 to the second mixture chamber 5. and mixes with a large amount of air entering from between the burner bodies. At this time, the primary air ratio is 1
After the mixture becomes a lean mixture of about 70% to 250% and is outside the flammable range and is homogenized, it is ejected obliquely from the second flame port 4 provided in the inclined section 23. The lean mixture is ignited by the thermal influence of the rich flame formed above the first flame port 1, resulting in lean combustion. The amount of thermal NOx generated decreases as the temperature of the combustion reaction zone becomes lower. Therefore, the leaner the mixture containing a larger amount of air, the higher the heat capacity, the lower the flame temperature, and the lower the NOx. Therefore, by reducing the amount of combustion of the rich flame and increasing the amount of combustion of the lean flame, the amount of NOx generated by this burner can be reduced. In our settings, the ratio of the lean flame combustion amount to the total combustion amount is 0.8 to 0.7, and the NOx value is 40.
It can be reduced to about ppm. However, with the conventional burner configuration, the ratio could only be increased to about 0.6, whereas with the burner of the present invention, the ratio could be increased to about 0.8 with the above configuration. be. As a result, the amount of NOx generated could be significantly reduced.

Furthermore, by configuring the burner body to consist of two parts, the burner body upper part 12 and the burner body lower part 11, the passage of the mixture air passage 15 can be achieved simply by changing the pitch in the longitudinal direction of the dowels 14 of the burner body upper part 12. It becomes possible to change the area, and the ratio between the combustion amount of rich flame and the combustion amount of lean flame can be adjusted by changing only the upper part 12 of the burner body. Therefore, it is possible to set the optimum ratio between the combustion amount of rich flame and the combustion amount of lean flame for various gas types.

On the other hand, the leaner the air-fuel mixture becomes, the more unstable the flame becomes, and eventually blow-off occurs. Next, flame stabilization will be explained. The air-fuel mixture supplied from the flame-stabilizing mixture passage 16 passes through the flame-stabilizing chamber 21 and is discharged from the flame-stabilizing chamber outlet 22. The area of the flame-holding mixture passage 16 is the area of the flame-holding chamber outlet 2.
By keeping the area smaller than 2, the flame holding chamber outlet 2
The speed of the air-fuel mixture ejected from the flame holding chamber 2 is slower than the speed of the air-fuel mixture ejected from the first flame port 1, and a more stable flame is formed above the flame holding chamber outlet 22. Due to the thermal effect of this auxiliary flame and the difference in flow rate of the ejected mixture, the rich flame formed above the first flame port 1 and the lean flame formed above the second flame port 4 are stabilized. In addition to suppressing the increase in combustion noise, it is possible to achieve low NOx combustion for the burner block as a whole.

Furthermore, when the amount of combustion becomes small, the jet flow velocity of the air-fuel mixture from the first flame port 1 and the second flame port 4 decreases, and the flame approaches the respective flame ports. Furthermore, if the supplied air amount fluctuates, the combustion amount will be small, so the air-fuel mixture inside the second air-fuel mixture chamber 5 may fall into the flammable range. At this time, the lean flame tries to advance into the second mixture chamber 5, but since the second flame port 4 is set to have a hole diameter smaller than the extinguishing diameter, Prevent flame from backfiring inside. Therefore, stable combustion can be obtained even if the amount of combustion is reduced.

Furthermore, the burner body upper part 12 regulates the width of the burner body upper part 12 around the facing dowel 14, and is connected to the burner body lower part 11 at the position of the dowel 14, and the injection plate 18 is integrally molded and bent. It is a plate material and is inserted into the groove 12a formed by the support 17 and the burner body upper part 12, and the vertical wall of the injection plate 18 and the wall part of the burner body upper part 12 are closely joined to each other, so that the burner block The overall rigidity increases and deformation does not occur. Therefore, it is possible to reduce variations in the mixture ratio of the second air mixture chamber 5 due to the occurrence of gaps that cannot be managed in terms of design, and to stabilize performance.

[Effects of the Invention] As explained above, the combustion apparatus of the present invention provides the following effects. 1) Compared to conventional methods, the combustion amount of a lean flame can be larger than that of a rich flame, so most of the fuel is combusted by the lean flame with a low flame temperature formed on the second flame opening. This makes it possible to achieve low NOx. 2) By being able to easily change the area of the inlet that supplies the air-fuel mixture to the first flame port, it is possible to set the optimum ratio of the lean flame combustion amount to the rich flame combustion amount for various gas types.
