[Problems to be solved by the device]

 In the conventional waste combustor described above, the main body of the combustion furnace was integrally molded on-site or in the factory, so when the combustion furnace body is molded on-site or the finished product is transported to the installation site. In that case, cracks and cracks were easily formed on the furnace wall during transportation, and the repair work was difficult.

Further, when the finished product of the combustion furnace main body is transported to the installation site, if the volume of the combustion furnace main body becomes large, for example, a large transport vehicle such as a large trailer or a large mobile crane such as a rough terrain crane. However, it was difficult to carry it into and install it at an installation site where there is only a narrow approach road such as a golf course. The present invention has been made in view of such a problem, and its purpose is to facilitate, in particular, the carrying-in and installation work at the installation site, and also to only the furnace wall block of the damaged portion of the combustion furnace body. The combustion furnace main body has a capacity that can be replaced, facilitates maintenance work, improves the durability of the furnace wall, and allows each furnace wall block to be rationally arranged so as to meet the installation conditions. It is to provide a waste combustion device that enables the formation of waste.

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a partially cutaway side view showing an outline of the entire waste combustion apparatus according to the present invention, FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and FIG. 3 is an enlarged view of a portion III in FIG. is there. The waste combustion apparatus of the illustrated example is mainly composed of a box-shaped combustion furnace body 1 having a combustion chamber 2 formed therein, and a chimney 3 fixed to the upper part with bolts, and an anchor bolt to the ground ( It is composed of a cyclone part 4 fixed to a base) and a tunnel-shaped flue 5 connecting the combustion furnace body 1 and the cyclone part 4.

The combustion furnace body 1 has an upper surface covered with a water cooling jacket (not shown), and is surrounded on four sides by a furnace wall 21 having a two-layer refractory castable structure composed of inner and outer castables 21a and 21b. Then, as shown in FIG. 1, an appropriate number of air ducts 10 are arranged in parallel in the horizontal direction around the outer surface of the furnace wall 21, and are fed from a blower (not shown) as an air supply device. Air is supplied to the inside of the combustion chamber 2 through an air port 22 formed in the furnace wall 21.

As shown in FIG. 2, the furnace wall 21 of the two-layer refractory castable structure constituting the combustion furnace body 1 is composed of, for example, a plurality of furnace wall blocks divided into four. That is, the furnace wall 21 includes a first block R ₁ and a second block R ₂ arranged laterally on the flue 5 side and an opposite side thereof, and a third block arranged longitudinally. and a four furnace wall blocks click R ₃ and the fourth block R _4. Each of the furnace wall blocks is connected to the adjacent furnace wall block by a mounting member 50.

Next, regarding the assembling and fixing between the furnace walls adjacent to each other, the second block R of the furnace wall ₂ And the fourth block R_FourAs an example, the details will be described below. As shown in FIG. 3, the mounting member 50 is provided at a joint portion between adjacent furnace walls, and is an L-shaped angle 51 that is integrally embedded and fixed when the outer furnace wall 21b is molded. And a plate-shaped fixing plate 52 having one end fixed to the angle 51 and the other end protruding outside the furnace wall 21, and the furnace wall block R adjacent to each other.₂And R_FourAnd a furnace wall block R, and a screw member 53 for joining the two fixing plates 52, 52 that overlap each other when they are abutted to each other by screwing.₂And R_FourAnd a seal member 54 such as ceramic wool fitted between the joining planes of the fixing plates 52, 52.

Each of the blocks R _{1 to} R ₄ is formed in an appropriate shape and size according to the function of each block. For example, as shown in FIG. 2, the first block R ₁ is provided with a communication hole 12 communicating with the flue 5, and the third block R ₃ is provided with an ash outlet 13. Further, each block is appropriately provided with the air port 22. The mounting member for fixing the other blocks has the same structure.
