The combustion gas generated in the combustion chamber 6 heats the vertical water pipes 3, passes through the hot combustion gas passage gap 4 between the vertical water pipes 3, heats the vertical water pipes 3, then heats the fins 9, and is finally discharged. Exhaust heat exits from the heat hole 10 into the annular flue 8.
上記燃焼ガスの流れによつて垂直水管３内の水
は熱交換されて蒸気となり、環状蒸気室１に送ら
れることになる。 Due to the flow of combustion gas, the water in the vertical water pipe 3 undergoes heat exchange and becomes steam, which is sent to the annular steam chamber 1.
フイン９は鉄板、ステンレス板等が良く、フイ
ン９の断面を少し山型状にして燃焼ガスが左右に
分流するように配慮している。
The fins 9 are preferably made of an iron plate, a stainless steel plate, or the like, and the cross section of the fins 9 is slightly chevron-shaped so that the combustion gas is divided to the left and right.
そしてこのフイン９は両端部を溶接により垂直
水管３に止着している。 Both ends of the fin 9 are fixed to the vertical water pipe 3 by welding.
この排熱孔１０は２mm程度が良く、この熱燃ガ

The present invention has an annular flue 8 of a vertical water pipe 3 as described above.
A fin 9 bent into a V-shaped cross section that closes the hot combustion gas passage gap 4 between the vertical water pipes 3 is attached to the side with the chevron-shaped bent portion on the outside. The heat is prevented from escaping to the path 8, and the convex bent part of the fin 9 prevents the heat from being discharged, and the heat is then guided to the back side of the vertical water pipe 3, through the heat exhaust hole 10 drilled just at the back side position. Annular flue 8
The vertical water pipe 3 is forcibly heated from the front and back, and at the same time, the heat of the directly heated fins 9 is also transferred to the vertical water pipe 3, so heat exchange is performed with an extremely excellent heat exchange coefficient. It turns out.
従つて熱効率の秀れたボイラになると共にそれ
だけ燃料費の節約も出来るから省エネルギー時代
に最適なボイラを提供することになる。 Therefore, it becomes a boiler with excellent thermal efficiency, and fuel costs can be reduced to that extent, thereby providing an optimal boiler for the energy-saving era.
また製作も垂直水管３にフイン９を溶接するだ
けで良いのであるから作業性に秀れると共に垂直
水管３同志をフイン９で連結することにより丈夫
