The steam furnace 16 is movably connected to the sealed outer shell 15 to ensure that steam does not leak out.

[0030] Specifically: A first motor 10 is fixedly connected to the side of the blower 9, and a gas supply pipe 11 is fixedly connected through the side of the blower 9. The other end of the gas supply pipe 11 is fixedly connected through the sealed outer shell 15 to improve combustion efficiency.

[0031] Specifically: an exhaust pipe 14 is fixedly connected through the other side of the furnace shell 1, a valve 13 is movably connected inside the exhaust pipe 14, a rotating shaft 20 is fixedly connected to the valve 13, and the rotating shaft 20 is movably connected through the exhaust pipe 14.

[0032] Specifically: A second motor 12 is fixedly connected to the side of the furnace shell 1, and the side of the second motor 12 is movably connected to the rotating shaft 20. An installation groove 21 is provided on the valve 13, and a sealing strip 22 is movably connected in the installation groove 21 to achieve precise adjustment of the exhaust volume and effectively prevent flue gas leakage.

[0033] Working principle:

[0034] Before boiler operation, the operator holds the first handle 5 and uses the rotating base 4 as a fulcrum to open the sealing door cover 2 around the side of the furnace shell 1, adding fuel and water to the furnace tank 18 and steam furnace 16 respectively. Then, the sealing door cover 2 is closed, utilizing its sealing structure with the furnace shell 1 to prevent heat leakage. Simultaneously, the second handle 8 is used to fasten the sealing cover 7 along the limiting post 6 to the heat dissipation hole 17 at the upper end of the furnace shell 1, forming a complete sealed space. The base 3 ensures the stability of the equipment operation. During startup, the first motor 10 drives the blower 9, and air enters the sealed outer shell 15 through the air supply pipe 11, providing sufficient combustion air for the steam furnace 16, improving fuel combustion efficiency. The generated heat is transferred to the water inside the steam furnace 16, causing it to heat up and vaporize to produce steam. During this process, the limiting groove 19 inside the furnace shell 1 provides stable support and positioning for the furnace tank 18, preventing displacement during high-temperature expansion. During operation, steam generated by the steam boiler 16 accumulates inside the sealed outer shell 15. When the pressure reaches the set value, the second motor 12 on the side of the boiler shell 1 drives the rotating shaft 20 to rotate, which in turn opens the valve 13 in the exhaust pipe 14, allowing steam to be discharged through the exhaust pipe 14. The sealing strip 22 installed on the valve 13 effectively prevents steam leakage. The second motor 12 precisely controls the opening and closing angle of the valve 13, enabling flexible adjustment of the exhaust volume and ensuring stable internal pressure of the boiler. In terms of heat management, the heat dissipation holes 17 at the upper end of the boiler shell 1 can promptly dissipate excess heat generated during boiler operation, preventing the boiler body temperature from becoming too high. The sealing cover 7, while ensuring airtightness, works with the heat dissipation holes 17 to maintain temperature balance inside the boiler. When maintenance is required inside the boiler, the operator can reopen the sealing door cover 2 and the sealing cover 7, and pull out the boiler tank 18 along the limiting groove 19 for easy cleaning of scale and inspection of component status. The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
