置されている。In addition, on the outer periphery of each block, a plurality of If lights 15 cut into appropriate lengths are vertically arranged. As shown in FIG. 7 and FIG. Consists of sixth and seventh blocks 16 and 18 divided into appropriate lengths in the horizontal direction, and on the outer periphery of these blocks,
Similar to each prong of the heat exchange section 2, a plurality of 9-ears 15 cut to appropriate lengths are arranged in the vertical direction. As shown in Fig. 10, it is divided into appropriate lengths in the horizontal direction, and on the outer periphery, there are a plurality of nodules 15 cut into appropriate lengths in the vertical direction, similar to each block of the heat exchange section 2. It is well placed.

低減させるととができる。 □The heat exchange section 2, combustion section 3, India house 4, and hora p+ 5 that make up the boiler 1 are divided into multiple blocks in advance by dividing them into lengths in the horizontal direction, and these blocks are assembled at the boiler construction site. The blocks 15 arranged longitudinally on the outer periphery of the blocks are butted against each other and then welded by automatic welding equipment or by a welder.
The construction of the boiler J is carried out by assembling each block in sequence from the force i without welding the 15 spaces. Since it is divided into multiple blocks and the tags for each block are cut to the appropriate length, there is no need to do any work such as reversing or pulling up when loading or unloading, and the system can be brought in and assembled on site just as it is. This increases work efficiency for transportation, reduces assembly man-hours, and significantly reduces costs. □
