３全体を均一に赤熱することが困難になる。The ceramic cylinder 1 has a diameter of 50 to 200 mm.
It has a desired thickness and a desired length. The cross section may be polygonal or another irregular shape other than the cylinder. The flame hole 31 may be a slit in addition to a round hole having a diameter of 1.0 to 5.0 mm, a polygonal hole, or a hole having another shape. The size of the flame hole 31 is large when the thickness of the burner element 3 is large,
If the diameter is small, it is set to be small, but if the diameter is smaller than 1 mm, the effect of reducing the ventilation resistance is small and normal pressure combustion cannot be performed smoothly. If the diameter of the burner hole 31 is larger than 5 mm, most of the air-fuel mixture passes through the burner hole 31 and the burner element 3
Since it does not diffuse into the inside, it becomes difficult to uniformly glow the entire burner element 3 facing the opening.

くなり燃焼状態が悪くなる。The size limitation of the thickness and density of the SiC fiber and the thickness of the burner element 3 is based on the following reasons. SiC
When the thickness of the fiber is smaller than 9 μm, the strength of the silicon carbide fiber surface structure is weak and handling becomes difficult. When the thickness is larger than 25 μm, the specific heat increases, and it is difficult to obtain a red-hot state during combustion. If the fiber density is less than 2.0 g / cm 3 , the strength is weak and the durability is insufficient, and the fiber density is 3.0 g / cm 3.
If it exceeds, the strength is strong, but the passage resistance of the combustion gas increases, and the combustion state deteriorates. Further, when the thickness is less than 2.0 mm, the strength is weak and the durability is insufficient, and the thickness is 15.0.
If it exceeds mm, the strength is high, but the passage resistance of the combustion gas increases, and the combustion state deteriorates.

３の表面の赤熱時間が短縮できる。In the surface combustion burner 100, for example, in normal-pressure combustion, the entire primary premixed gas having an excess air ratio λ = 0.9 to 1.2 is supplied to the ceramic cylinder 1 and ignited by an ignition device (not shown) to ignite. I do. The combustion is performed at the outlet of the flame hole 31 and near the outer surface of the burner element 3, and the SiC fiber is heated and glows red. In this combustion, the flame 32 of the flame hole 31 is instantaneously formed, and the surface of the burner element 3 begins to glow from the periphery of the flame hole 31 due to the heating of the flame 32 and rapidly expands. Therefore, the red heat time on the surface of the burner element 3 can be shortened as a whole.

る。The surface burning burner 100 of this embodiment can be designed to have a desired shape of the opening (the shape of the surface burning portion), is excellent in decorativeness, and is excellent in workability and assemblability. In addition, when installed in a fireplace and used for heating, there is an advantage that the atmosphere can be enjoyed. The surface combustion burner as another embodiment of the present invention can be applied to a forced air supply type (pressure combustion type) burner using a forced air supply means such as a blower. In this case, the flame holes 31 and It is necessary to adjust the ventilation resistance of the burner element 3 to be suitable for pressurized combustion.
