管の下部のJ型端部が燃焼室外にでるようにし、燃焼室
外の最底部は加熱されないようになつているが、本考案
においては蒸発管の下部のJ型端部を燃焼室外に出す必
要がない。In the above-mentioned prior invention (Japanese Patent Application No. 59-234567), the J-shaped end of the lower part of the evaporation tube is exposed outside the combustion chamber, and the bottommost portion outside the combustion chamber is not heated. In the above, it is not necessary to let the J-shaped end of the lower part of the evaporation tube out of the combustion chamber.
またブロー管は管寄せに接続するようにならしめてあ

するなど数々の利点がある。Since the present invention is connected to the lower part of the evaporation tube by forming a pipe-drawing structure that surrounds the circumference of the furnace, it has the advantage of completely eliminating problems such as burnout and post-boiling due to the heat storage amount of the furnace. Instability of circulation and accumulation of scale in the evaporation pipe, which is caused by the J-type of conventional multi-tube type once-through boiler, and further, burning and rupture due to overheating are prevented, and the structure is simple and inexpensive. It can be manufactured, the safety factor is high, and the steam separator is installed in the upper steam chamber of the evaporation pipe.
Furthermore, if the upper evaporation pipe on the upper part is covered with a refractory material or a heat insulating material, the dryness of the generated steam becomes high, the heating is prevented and the quality of the steam is improved. By installing it at an angle of 3 degrees or more, it is possible to expel bubbles generated in the header to the evaporation pipe side as quickly as possible, and there is no trouble due to bubble stagnation and boiler safety is improved. There are many advantages, such as a significant increase.
