It can be provided in multiple stages, and the planar winding shape can be appropriately selected from circular, square, pentagonal, hexagonal, etc. according to the shape of the combustion chamber 2, and can be configured to prevent rice husk and scum. Evenly spaced gaps are provided so that the vortex burns above the vortex tube.

In the above embodiment, water at room temperature is pushed into one end of the lowest spiral tube 3a from the lower end 21 of the cooling chamber 4 using gravity, and from a position below the water level of the water supplied into the cooling chamber 4. Although a gravity-type water supply system is adopted to take out heated hot water, the present invention is not limited to the above embodiment, and a pump is installed at one end of the vortex tube attached to the upper or lower part of the combustion chamber 2. (not shown) can be attached to allow water to pass through the spiral tubes provided in multiple stages under the pressure of a pump.

The embodiment of the present invention is constructed as described above,
When a fuel 22 with a slow burning rate, such as rice husk or scum, is injected into the combustion chamber 2 from the fuel inlet 6, the fuel is filled up to the top of the uppermost spiral tube 3c, and ignited from the bottom of the combustion chamber 2. 22 gradually burns, directly heating the swirl tubes 3a, 3b, and 3c, heating the water in the swirl tubes to raise it to an appropriate temperature, and causing it to flow into the heat exchanger tube 23 of the heat exchange chamber 5 from one end of the swirl tube 3c. .
