面燃焼バーナがある。[Prior Art] Conventionally, particles having excellent fire resistance are formed into a porous auxiliary combustor with a special binder, and a mixed gas of fuel gas and air passes through the fine gaps between the particles of the auxiliary combustor. There are surface burners that burn on the surface.

る。This surface-burning burner has a good gas flow on its surface due to the uniform gas flow formed in the interparticle gaps and the mixing effect of the fuel gas and air achieved during the passage between the irregularly changing particle gaps. Surface combustion takes place. However,
As shown in FIG. 3, in a surface combustion burner having a cylindrical auxiliary combustion body having a large combustion surface, the tip end and the base end portion change due to a change in the internal pressure (static pressure) P 2 applied to the surface of the auxiliary combustion body. There is a problem that the combustion loads differ between and.

されている。That is, in FIG. 3, the auxiliary burner 1 in which ceramic particles are formed in an elongated cylindrical shape by an inorganic binder forms a cylindrical internal space 2 for distributing the mixed gas therein. One end of the auxiliary burner 1 is closed by a closing plate 5 made of the same material as the auxiliary burner 1, and the other end is held by a support 6.
The support 6 is provided with a mixed gas supply port 7,
The mixed gas supply port 7 communicates with the internal space 2 of the auxiliary burner 1. Then, the support rod 9 and the closing plate 5 provided on the support body 6
Are connected to each other by the connecting and fixing member 8, and therefore the closing plate 5 is fixed to the auxiliary burner 1 by this connecting and fixing member 8.

る。In the above-mentioned configuration, the mixed gas supplied from the mixed gas supply port 7 flows in the internal space 2 toward the closing plate 5, and a part of the mixed gas is generated by the static pressure of the mixed gas.
Due to the above-mentioned special effect of the auxiliary burner 1, good combustion is performed on the surface thereof. However, as shown in FIG. 3, the static pressure P 2 in the internal space 2 of the auxiliary burner 1 is
The mixed gas supply port 7 side is small, and the closing plate 5 side is large. According to Bernoulli's theorem, the mixed gas supply port 7 side has a large dynamic pressure and a small static pressure, while the closing plate 5 side converts the dynamic pressure of the mixed gas into a static pressure. This is because the static pressure increases. As described above, since the static pressure P 2 exists in the internal space 2 of the auxiliary burner 1, the mixed gas amount passing through the auxiliary burner 1 is different between the mixed gas supply port 7 side and the closing plate 5 side. Therefore, as shown in the figure, there is a problem that high load combustion is performed only on the closing plate 5 side, and a surface combustion burner that performs uniform load combustion cannot be obtained.

The plate 3 is arranged in a substantially horizontal state. This adjusting plate 3
This is for partially reducing the flow passage cross-sectional area of the mixed gas in the internal space 2, and its outer diameter is smaller than the inner diameter of the auxiliary burner 1, and the outer peripheral edge of the adjusting plate 3 and the inner wall surface of the auxiliary burner 1 A mixed gas flow path A is formed between them. The flow passage cross-sectional area of the mixed gas flow passage A is preferably about 1/2 of the internal cross-sectional area of the auxiliary burner 1. That is, the area of the adjusting plate 3 is about half the internal cross-sectional area of the auxiliary burner 1.

負荷燃焼が行われることになる。In the above structure, the operation will be described. The flow of the mixed gas supplied from the mixed gas supply port 7 is blocked by the adjusting plate 3, and a part of the dynamic pressure is converted into static pressure. Static pressure is increased. Due to this, the mixed gas flow having a low dynamic pressure flows from the mixed gas flow path A formed between the inner wall surface of the auxiliary burner 1 and the outer peripheral edge of the adjusting plate 3 to the closing plate 5.
The dynamic pressure is converted into static pressure by the closing plate 5. As described above, since the dynamic pressure of the mixed gas flow is converted into the static pressure by dividing the static pressure by the action of the adjusting plate 3, the static pressure is further increased like the static pressure P 1 shown in FIG. Are equalized. Therefore, the amount of the mixed gas passing through the auxiliary burner 1 is made more uniform, and the flame F 1 formed on the surface of the auxiliary burner 1 is leveled as shown in FIG. Heavy load combustion will be performed.

However, the present invention is not limited to this.
If the flow passage cross-sectional area of the mixed gas flow passage A formed between the inner wall surface of the auxiliary burner 1 and the outer peripheral edge of the adjusting plate 3 is about 1/2 of the internal cross-sectional area of the auxiliary burner 1, the polygon Even with a shaped adjusting plate, the static pressure is equalized, as in the case of a disc shape. Further, in the description of the above-described embodiment, the case where one adjustment plate 3 is provided has been described, but when the distance from the mixed gas supply port 7 to the closing plate 5 is long and therefore the influence of the dynamic pressure change is large, adjustment is performed. It is preferable to provide a plurality of plates 3 and arrange them at substantially equal intervals.

In this embodiment, the adjusting plate 3 is provided with a plurality of through holes 4 of appropriate size. According to this configuration, the flow of the mixed gas is also formed in the central portion of the internal space 2 of the auxiliary combustion body 1, the influence of the dynamic pressure on the inner wall surface of the auxiliary combustion body 1 on the downstream side of the adjustment plate 3 is reduced, and The pressure equalization becomes more effective.

Therefore, the static pressure acting on the inner wall surface of the auxiliary burner can be more effectively equalized over the entire inner wall surface, and uniform load combustion on the outer surface of the auxiliary burner can be achieved. Further, by providing the adjusting plate with the through hole, the influence of the dynamic pressure on the downstream side of the adjusting plate can be mitigated, and the load combustion can be made uniform.
