ようにしていた。(B) Prior art As disclosed in Japanese Utility Model Publication No. 52-48036 (see Figure 1), a conventional single-fire hot water boiler has a bottomed cylindrical outer cylinder (1) and a cylinder (2). A water pit (4) with an ice chamber (3) formed between them is provided, and a gap serving as a combustion gas flow passage (5) is placed inside the water pit (4), and a baffle (6)...
A baffle tube (7) with a large number of ... placed upright on the water spatula (4) side is arranged, and a combustion chamber (9) with a burner (8) facing downward is formed inside the baffle tube (7). Burna (8)
), the fuel and combustion air are injected and combusted in the combustion chamber (9), the combustion gas is reversed on the bottom of the water pit (4) and supplied to the combustion gas flow passage (5), and the combustion gas is injected into the baffle ( 6
), the water was brought into contact with the water pipe (2) to exchange heat with the water in the water pipe (4), and then exhausted from the flue (g).

った。However, in the hot water boiler described above, the temperature of the combustion gas decreases as it goes to the upper part of the combustion gas flow passage (5), so the combustion gas is combusted at the upper part of the combustion gas flow passage (5) via the bathoflu cylinder (7). There was a drawback that heat from the chamber (9) was taken out and radiated directly to the atmosphere through the flue αQ. Therefore, even if the number of baffles (6) is increased and the heat transfer area is increased, the amount of heat flowing from the combustion chamber (9) to the combustion gas flow passage (5) increases in proportion to the heat transfer area, and the heat exchange Efficiency could not be improved sufficiently.

・Alumina is applied to the entire inner wall of the baffle tube (7) with
Since the refractory material (b) made of silica fiber etc. is attached, there is little heat transfer from the combustion chamber (9) to the combustion gas flow path (5), but the refractory material αη receives the flow of combustion gas. It easily deteriorates and cannot withstand long-term use.
The amount of refractory material (b) used was larger than necessary, making it uneconomical.

装箱（至）の外部へと排気される。In the hot water boiler configured as described above, when the burner fan (■) is operated and fuel (kerosene) is sprayed from the nozzle (2), the fuel and combustion air flow through the rectifying plate (C) attached to the draft cheep (C). It passes through the rectifier tube (a) and advances while being stirred into the rectifier tube (a), and further advances below the rectifier tube (a) where it is combusted. The combustion gas is reversed at the bottom of the boiling pot (6) and ascends through the combustion gas flow path α between the baffle cylinder (g) and the boiling pot (6). Then, by the action of the baffle, the water in the ice chamber C10 is heated by coming into contact with the inner cylinder α→, and then is exhausted from the flue to the outside of the outer box.

The fuel that is returned to the upstream side of - and passes through the inside of the straightening tube receives combustion heat and vaporizes.
このため、バーナ（２）による燃焼はガス化燃焼となる

ため、無駄がない。According to this embodiment, the heat insulating material (2) is placed in parallel on the inner circumferential surface from the upper end of the Bakuful tube to the middle part below the rectifying tube of the burner. , combustion chamber (2
) from the top of the combustion gas flow passage a0 to the upper hebanoful cylinder (
It should be possible to prevent heat from transferring through the heat insulating material (g), and to prevent the heat insulating material (b) from deteriorating by being blocked from the flow of combustion gas. Moreover, since the metal tube () is made of a metal material that has a higher heat resistance temperature than the panful tube (g), there is no need to worry about the metal tube () being deformed by heat. In addition, the baffle tube (T)
Since there is no heat insulating material in the middle and lower part, heat moves from the combustion chamber (c) to the combustion gas flow passages α in this part. However, the combustion gas heated by this heat transfer hits the baffle screen and exchanges heat with the water in the water tank (6), so there is no waste.

When using a recirculation type with a straightening tube installed in front (below) of the burner, the temperature in the combustion chamber surrounding the burner (a) is set at 1000°C in order to promote vaporization of the fuel by recirculating the combustion gas.
It is preferable to maintain the temperature at a higher temperature. In this embodiment, the area from the upper end of the baffle cylinder OF9 to the lower intermediate portion of the burner (2) is made of a double wall with a heat insulating material interposed therebetween, so that the combustion chamber (to) around the burner (A) is constructed as described above. It is possible to maintain a high temperature state and perform cassification combustion well. In addition, the metal cylinder constituting the inner wall of the double wall is made of Fe-Cr.
-Aj! The use of electrically heated alloy plates provides sufficient durability even under such high-temperature conditions, and since alumina is formed on the metal surface on the combustion chamber side, it is resistant to oxidative corrosion.

な備えたものに最適である。(f) Effects of the Invention As is clear from the above description, the present invention includes metal cylinders arranged side by side with a heat insulating material interposed on the inner peripheral surface from the upper end of the baffle cylinder to the middle part below the burner, This metal tube uses a metal material with higher heat resistance than the panfur tube, so a small amount of heat insulation material prevents the transfer of heat from the combustion chamber to the upper part of the combustion gas flow path via the buckle tube, making it economical. It is possible to increase the amount of heat exchange efficiently and efficiently, prevent the insulation material from deteriorating due to exposure to the flow of combustion gas, and ensure sufficient durability of the metal cylinder that protects the insulation material. This makes it possible to extend the life of the device, and is particularly suitable for devices equipped with recirculation type burners, where the upper space of the combustion chamber is in a high temperature state.
