Abstract

(57) [Summary] (Correction) [Purpose] In a water-cooled incinerator, the expansion of the furnace wall due to the expansion of cooling water is suppressed easily and at low cost. [Structure] A reinforcing frame 3 is interposed between a furnace inner wall 1 and a furnace outer wall 2, and both ends of the reinforcing frame 3 are fixed to the furnace inner wall 1 and the furnace outer wall 2 by welding or fixed with bolts, nuts or the like. Also,
The reinforcing frame 3 may also serve as the wall of the air hole.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water-cooled incinerator that incinerates combustible industrial wastes, and more specifically, a furnace wall designed to easily and economically suppress expansion of the furnace wall due to expansion of cooling water. It is about structure.

[0002]

[Prior art]

 In the conventional water-cooled incinerator, the furnace wall was provided with an appropriate space between the inner and outer walls made of iron plates, and water was poured into the space to cool the furnace wall. In order to prevent the swelling of the iron plate due to the expansion of water, the iron plate of the furnace wall was reinforced with internal rib materials and external headband materials, which had the drawbacks that the reinforcement work was troublesome and the cost was high. It was

[0003]

[Problems to be solved by the device]

 This invention has been made in order to solve the drawbacks described in the prior art, and provides a structure of the furnace wall of a water-cooled incinerator that can easily and economically suppress the swelling of the furnace wall due to the expansion of water. It is intended.

[0004]

[Means for Solving the Problems]

 A reinforcing frame is interposed between the inner wall of the furnace and the outer wall of the furnace, and both ends of the reinforcing frame are fixed to the inner wall of the furnace and the outer wall of the furnace. The reinforcing frame may also serve as the air hole wall.

[0005]

[Action]

 Since the reinforcing frame that also serves as the reinforcing frame and the air hole wall acts to prevent outward displacement of the furnace inner wall and the furnace outer wall, it is possible to prevent swelling of the reactor inner wall and the furnace outer wall due to water expansion. The work of attaching the reinforcing frame is simple and inexpensive. Also, it is convenient because the reinforcing frame can be used as an air hole or a peephole.

[0006]

EXAMPLE An explanation will be given of a drawing showing an example of the practice of the present invention. In a water-cooled incinerator, an iron reinforcing frame 3 is provided at an appropriate position between an inner wall 1 of an iron plate and an outer wall 2 of an iron plate. Both ends of the reinforcing frame 3 are fixed to the inner wall 1 and the outer wall 2 of the furnace by welding or mechanically fixed.

Although air holes (4) are provided at appropriate places in the furnace wall, it is preferable to use the reinforcing frame 3 also as the wall of the air holes (4) because it can be finished more economically. The shape of the reinforcing frame is not particularly limited, but generally rectangular or round shape is often used.

[0008]

【effect】

 Since the present invention is configured as described above, it has the following effects.

The swelling of the furnace wall due to the expansion of water can be suppressed easily and inexpensively.

Since the reinforcing frame can be used as an air hole and a peephole, it is economical.

The reinforcing material for the furnace wall can be greatly reduced as compared with the conventional one, and the construction cost for mounting can be reduced, so that the cost of the incinerator can be reduced. This device has the remarkable effects as described above, and its industrial utility value is high.
