FIG. 3 is a longitudinal sectional view of one embodiment of the present invention, and FIG. 4 is a sectional view taken along the section line - in FIG. The furnace main body 9, which has a cylindrical shape with an open top and a bottom, is formed by lining the inner surface of a casing 10 with a heat insulating material 11. A non-ferrous metal 13 such as aluminum or zinc is charged into a melting pot 12 placed so as to close the upper open end of the furnace body 9. Further, a surface combustion burner 14 is provided in the middle of the furnace body 9 so as to face the side portion 12a of the melting pot 12. Therefore, the non-ferrous metal 13 in the melting pot 12
is uniformly heated and melted by the surface combustion burner 14. On the other hand, the combustion exhaust gas from the surface combustion burner 14 is discharged through an exhaust port 15 provided at the upper part of the furnace body 9.

気孔を有する耐火物あるいは焼結金属から成り、
ガスの流過を許容する。 The main body 16 of the surface combustion burner 14 has an annular shape, and its radial cross section is formed into a substantially U-shape that opens radially inward. A melting pot 1 is provided at the inner open end of the main body 16.
A combustion part 17 is provided opposite to the side part 12a of 2. This combustion part 17 is made of ceramic fiber,
Made of refractory or sintered metal with pores,
Allow gas to flow through.
なお前記本体１６は、非鉄金属１３を装入した
溶解鍋１２、および炉本体９の表面燃焼バーナ１
４よりも上方の部分９ａを支持するに充分な強度
を有して構成されている。 The main body 16 includes a melting pot 12 charged with non-ferrous metal 13 and a surface combustion burner 1 of the furnace main body 9.
It is constructed to have sufficient strength to support the portion 9a above the portion 4.

は、燃焼部１７を流過する際に燃焼反応を生じ、
それによつて赤熱した燃焼部１７からの熱輻射に
より溶解鍋１２が加熱される。 An annular space 18 is formed between the combustion part 17 and the outer part 16a of the main body 16 along the radial direction. A mixed gas of gaseous fuel and combustion air is supplied to this space 18 through a gas supply pipe 19 connected to the outer portion 16a. This mixed gas causes a combustion reaction when flowing through the combustion section 17,
As a result, the melting pan 12 is heated by heat radiation from the red-hot combustion section 17.

１２が局部的に過熱することが防止されて耐久性
が向上するとともに、非鉄金属１３の溶解保持温
度が均一となる。 During the combustion reaction in the combustion section 17 as described above, no large fire is formed on the inner surface of the combustion section 17. Therefore, the surface combustion burner 14 can be provided close to the melting pot 12, and the furnace body 9 can be downsized accordingly. Also, due to the effect of flow resistance when flowing through the combustion section 17,
The mixed gas does not flow concentrated in a part of the combustion section 17. Therefore, the combustion section 17 has a substantially uniform temperature over the entire circumference. Therefore, the melting pot 12 is prevented from being locally overheated, its durability is improved, and the melting and holding temperature of the non-ferrous metal 13 becomes uniform.

も炉本体９を小形化することができる。 Further, since it is not necessary to cover the outer side of the surface combustion burner 14 in the radial direction with a heat insulating material, the construction of a heat insulating material is not necessary, and the weight of the furnace body 9 is reduced. Furthermore, since there is no need to provide a combustion chamber 5 unlike the prior art shown in FIGS. 1 and 2, the furnace body 9 can be downsized from this point as well.

を定めればよい。 Regarding the area where the surface combustion burner 14 is provided, the height h from the bottom 9b of the furnace body 9 depends on the amount of heat required to melt and hold the nonferrous metal 13.
All you have to do is determine.

形化することができる。 As described above, according to the present invention, the surface combustion burner is provided around the entire circumference so as to face the side of the melting pot, so the furnace body can be made smaller and the melting pot can be heated evenly. It is possible,
Therefore, the melting and holding temperature can be made uniform. That is, in the present invention, in the combustion section 17 of the surface combustion burner 14, a large flame is not formed on the inner surface of the combustion section 17 during the combustion reaction. Therefore, the surface combustion burner 14 can be provided close to the melting pot 12, and the furnace body 9 can be downsized accordingly.

温度が均一となる。 Further, due to the effect of the flow resistance when flowing through the combustion section 17, the mixed gas does not flow concentrated in a part of the combustion section 17. Therefore, the combustion section 17 has a substantially uniform temperature over its entire circumference. Therefore, the melting pot 12 is prevented from being locally overheated, its durability is improved, and the melting and holding temperature of the non-ferrous metal 13 becomes uniform.

きる。このように本考案によれば、幾多の優れた
効果が達成されることになる。 Furthermore, in the present invention, since there is no need to cover the outside of the surface combustion burner 14 in the radial direction with a heat insulating material, there is no need to install a heat insulating material, and the weight of the furnace body 9 is reduced accordingly. Furthermore, unlike the prior art shown in FIGS. 1 and 2, there is no need to provide a combustion chamber 5, so that the furnace body 9 can be downsized from this point as well. As described above, according to the present invention, many excellent effects can be achieved.
