Japanese Patent Publication No. 60-9210 is well known,
The side wall structure of this refuse incinerator will be described with reference to FIGS.

ている。[0004] First, as shown in FIG. 4, the input refuse a is composed of a dry grate b, a combustion grate c and a post-combustion grate d.
It burns while being transported above, and the incineration ash is discharged to the conveyer tank e. Then, the side wall portion which is most likely to rise in temperature during combustion has an air-cooled plate structure equipped with an air-cooled plate brick f, and the other side wall portion g has a general brick structure.

The support bolts j are inserted into the lattice support plates k arranged in a lattice pattern via the support members j, and are juxtaposed vertically and horizontally. The mounting bolts n are formed in the through holes formed by the notches m at the four corners of the adjacent air-cooled plate brick f. And the nut r provided on the brick support plate k is screwed into the mounting bolt n to hold the air-cooled plate brick f and air-cool the back surface of the air-cooled plate brick f.

返している。したがって、側壁を構成するレンガ表面

変動に応じて絶えず膨張収縮を繰り返すことになる。Here, since the calorific value of the refuse greatly fluctuates, the temperature in the incinerator, especially in the combustion zone, fluctuates greatly, for example, 1050 to 750 ° C. Therefore, the brick surface constituting the side wall constantly expands and contracts in accordance with fluctuations in the furnace temperature, even though the back surface is cooled by air.

除々に欠落を生ずるという問題があった。However, in the above-mentioned conventional structure, the inside half of the incinerator of the air-cooled plate brick f is in close contact with each other, and the outside half of the incinerator is in direct contact with the brick support plate k and is fastened by the mounting bolts n at the four corners. Even if the air-cooled plate brick f and the brick support plate k expand and contract due to fluctuations in the incinerator temperature, they can only respond within a limited range and cannot freely expand and contract, and have a complicated structure. Dimensional accuracy and finished surface are difficult to obtain. For this reason, mutual interference occurs between the air-cooled plate bricks f and the brick support plate k, which causes cracks or peeling at the center portion, and causes the bolts to gradually drop off from the bolt fastening surfaces at the four corners. Was.

いた。Further, when the incinerator is started after the shutdown, cooling air leaks into the incinerator from the gap formed between the air-cooled plate brick f and the brick support plate k and the defective portion of the air-cooled plate brick f, and In addition to hindering temperature rise, during normal operation, air leaking from the gap causes abnormal secondary combustion near the gap, creating a local high-temperature region, causing clinkers to occur. At times, there is a problem such as excessive combustion caused by the leaked air and burning out of the fire, which has been an obstacle when applied to facilities that perform intermittent operation.

2分割している。A plurality of partition plates 4 made of, for example, H-shaped steel are provided on the back of the air-cooled slab brick body 1 to separate and send the flow of cooling air for each row of the air-cooled slab brick body 1 in the vertical direction.
Are installed in parallel, and an air cooling plate casing 9 is attached to the outside of the partition plate 4 to divide the rear surface of the side wall into an outer common first air layer 10 and an inner plurality of second air layers 11. ing.

After the mounting bolts 6a inserted into the bolt holes 2 of the air-cooled slab brick body 1 are inserted through the support members 5, the two are fixed together with the nuts 6b, so that the air-cooled slab brick main body 1 is connected to another adjacent air-cooled plate. It is separated from the brick body 1 by the amount of the expansion allowance and is supported so as to be stretchable. Thus, the air-cooled brick body 1 and the mounting bolts 6a can freely cope with expansion and contraction movements, and the air-cooled brick body 1 is not damaged by thermal stress.

防止している。Further, a T-shaped or flat sealing plate 7 and an air-cooling plate brick sandwiching the sealing plate 7 are provided on the outer portion of the incinerator at the expansion allowance formed between the peripheral side surfaces of the adjacent air-cooling plate brick main bodies 1. A sealing member composed of a sealing member 8 having an L-shaped cross section and having elasticity and disposed from the shoulder to the peripheral side surface of the main body 1 is interposed. From leaking into the incinerator.

上する。As described above, the air-cooled plate brick main body 1 has a simple structure, so that the finished surface can be smooth and the finished surface is smooth. In addition, since the back surface has a relatively small amount of expansion and contraction, the air-cooled plate brick can be entirely sealed. The sealing performance is dramatically improved.

返す断続運転の焼却施設にも有効である。As described above, according to the present invention, the bricks are fixed to the supporting material supporting the back surface of each brick at the central portion by taking an appropriate expansion allowance between the bricks. Since the material is flexible, the expansion and contraction movements of the brick and the fixing bolt due to the heat fluctuation are free, and the brick is not damaged by cracks, peeling or missing due to thermal stress. Therefore, the sealing performance of the entire brick is greatly improved in combination with the back sealing method using a sealing member made of a sealing material and a sealing material inserted from the back of the brick to the peripheral side surface of the brick. Therefore, leakage of cooling air into the furnace hinders rise in furnace temperature during startup, local rise in furnace temperature during normal operation, resulting in clinker adherence to the furnace wall or insufficient cooling air flow, and during fire It is possible to prevent troubles such as excessive combustion, and it is effective not only for all continuous operation but also for incineration facilities with intermittent operation that repeats burning, shutdown, and start-up operation.

Brick installation or replacement work is facilitated, and site construction costs and work days can be reduced. Further, since the air-cooled portion has a two-layer structure, the outer air layer serves as a heat insulating layer for the inner air layer, so that the cost of the heat insulating material can be reduced.
