かなり面倒なものとなる欠点があつた。 In order to prevent the spout, which is made of steel plate, from overheating and high-temperature corrosion due to the smelt that reaches temperatures of approximately 830°C from inside the boiler's furnace, cooling water is poured into the steel pipe that forms the outer shell of the spout, as mentioned above. The steel plate was protected by passing it through. However, the steel pipes that form the framework of such spouts are
If the reactor were to burst for some reason and the cooling water leaked into the hot smelt, there was a risk that it would eventually lead to an explosion. In addition, as mentioned above, this spout requires a cooling water system, which makes the structure around the spout and the furnace wall complicated, and its installation and handling methods are also quite troublesome. It was hot.

の間に十分な間隙を有したまま固定される。 The spout 1 is then inserted in parallel to the longitudinal direction on the inner surface of the support base 2. In this case, the spout 1 is not in direct contact with the support base 2,
It is fixed with an appropriate gap. That is, according to this embodiment, a liner 3a for stabilizing the spout, which is a curved plate along the radius of the U-shape, is placed at an appropriate position at the bottom of the U-shaped gap created by these. 1 is placed on a support base 2 before being fixed. A liner 3b between the sides made of a flat plate is also placed at an appropriate position on the sides near the center of this gap.
are entered respectively. Furthermore, as mentioned above, since the shape of both ends of the spout 1 in the longitudinal direction is narrow, the shape of each end of the spout 1 and the support base 2 are narrow.
A wedge-shaped space is defined between the liners 3 and 3, and wedge-shaped liners 3c and 3d are respectively driven into these spaces for setting the mounting position, and thereafter, as shown by reference numeral 4 in FIG. Then, the two are fixed by welding, whereby the spout 1 and the support base 2 are fixed with a sufficient gap between them.

内からスパウト１上に流出しやすくされている。 The support base 2 supporting the ceramic spout 1 in this manner is then attached to the outside of the smelt outlet 6 provided at a suitable position on the furnace wall 5 of the soda recovery boiler. That is, according to this embodiment, the spout 1 and the support base 2 are mounted on the mounting plate 7.
A supporting stand 2 is attached to this mounting plate via a reinforcing bracket 8 so as to be inclined downwardly toward the outside of the furnace. This mounting plate 7 has a plurality of bolts and
It is attached by a nut 10. Spout 1

十分高めることができる。Effects of the invention As detailed above, according to the invention, the spout for discharging smelt from the inside of the furnace to the outside of the furnace is made of ceramic material, so it has good heat resistance, corrosion resistance, etc. against high-temperature smelt. Moreover, since the support base is placed outside the ceramic material, it is possible to sufficiently increase the strength against impact force, which has been a problem with conventional ceramic materials.

することができる。 Moreover, in this case, since both ends of the spout in the longitudinal direction are constricted, it will not float up or slide down, thereby reliably preventing the spout from falling off the support base. In addition to this, the gap between the spout and the support base can reduce heat transfer from the smelt, so thermal deformation of the support base can be minimized.Furthermore, according to the present invention, thermal deformation of the support base can be minimized. Since there is no need to cool the spout with cooling water, there is no need for conventional cooling water system equipment, and there is no need to worry about explosions or explosions caused by the use of cooling water, and the overall structure of the device is simplified. Costs can be reduced considerably.
