The utility model discloses a theory of operation of embodiment:
the topmost part of the furnace body is provided with a steam superheater 8 for converting saturated steam into superheated steam. Saturated steam enters the steam superheater 8 from the steam superheater inlet 11, is converted into superheated steam in the steam superheater 8, and is discharged from the superheated steam outlet 5. Because the steam superheater 8 does not contain moisture, the internal volume of the steam superheater 8 is not calculated into the effective water volume of the boiler, and the normal water volume of the boiler can be effectively reduced.
The upper end cover 6 is positioned at the uppermost end of the furnace body and is fixed by screws, so that the furnace body is convenient to disassemble. When the flue needs to be overhauled or cleaned, the upper end cover 6 is disassembled and moved away, and the flue in the furnace can be cleaned.

The upper end cover 6, the fire-resistant layer 7, the steam superheater 8 and the hot water preheating pipe 16 form a whole body, and are removed together when being disassembled.
The innermost layer of the furnace body is provided with a hot water preheating pipe 16, cold water enters the hot water preheating pipe 16 through an inlet 10 of a hot water preheater, the cold water is discharged from an outlet 9 of the hot water preheater after being heated, and then enters a heat preservation water tank for storage, and the preheated low-temperature water enters a water inlet 2 through a water pump for heating. Because the hot water preheating pipe 16 is in a normal pressure state, the water volume of the pipeline is not recorded in the water volume of the normal water level, and the water volume can be effectively reduced under the condition of the same evaporation capacity.
The combustion flame enters from a flame inlet 18 at the bottommost part of the furnace body, the flame passes through the inner side of the inner spiral pipe 15, heats the inner side of the inner spiral pipe 15 through radiation, simultaneously heats the hot water preheating pipe 16 and the steam superheater 8, the flue gas passes through a first return flue from bottom to top, enters a second return flue from top to bottom at the topmost end, mainly heats the outer layer side of the inner spiral pipe 15 and the inner side of the outer spiral pipe 14, finally enters a third return flue from bottom to top, and finally is discharged from a smoke outlet 13. The smoke outlet 13 is positioned at the left side of the uppermost part of the furnace body.
Air required by combustion flame enters the preheating channel from top to bottom through the air preheating inlet 4, and heat is mainly absorbed from the outer layer 3 of the furnace body and is finally discharged from the air preheating outlet 17. The air preheating reduces the exhaust gas temperature, improves the combustion air supply temperature and improves the overall heat efficiency.
