[0004] During the actual application process, the applicant found that when the combustion chamber's flame spraying area sprays fire, the flame heats the inner coil structure. During heating, due to the gaps between the traditional inner coil structures and the openings on the top, the flame utilization rate is low when the combustion chamber's flame spraying area sprays fire, and the excess heat cannot be utilized. Instead, it is directly lost through the gaps between the inner coil structures or the openings on the top, resulting in a serious waste of resources and being unfavorable to actual application and operation.

The heating zone 2 is located at the top of the preheating zone 1, and the superheating zone 3 is arranged inside the preheating zone 1 and below the heating zone 2. The preheating zone 1 and the heating zone 2 are in a sealed state. The preheating zone 1 and the heating zone 2 form a sealed chamber, so that the flame ejected from the combustion chamber can stay inside the device, and the superheating zone 3 is fully heated, thereby making great use of the excess flame, and preventing most of the heat from overflowing and causing losses. The energy-saving effect is significantly improved, the utilization rate of the flame is increased, and the waste of resources is avoided, which is conducive to practical application and operation.

[0031] Reference Figure 1 , Figure 2 and Figure 3In one aspect of the present embodiment, the preheating zone 1 includes an outer ring tube 11, which is tightly wound to form a barrel-shaped structure. In addition, the preheating zone 1 also includes a water inlet pipe 12, which is fixed to one end of the outer ring tube 11 away from the coil 21 and communicates with the inside of the outer ring tube 11. Since the outer ring tube 11 is tightly wound to form a barrel-shaped structure, the device can be sealed, and the flame ejected from the combustion chamber will not overflow too much, thereby avoiding energy loss.

[0032] Reference Figure 1 and Figure 2 In one aspect of the present embodiment, the heating zone 2 includes a coil 21, which is tightly wound to form a mosquito coil disc structure, and the coil 21 and the outer ring tube 11 are in a sealed state, and the coil 21 is connected to the inside of the outer ring tube 11. Since the coil 21 is tightly wound to form a mosquito coil disc structure, the flame ejected from the combustion chamber will not overflow too much through the top of the device, further avoiding energy loss. The outside of the coil 21 and the outer ring tube 11 can be wrapped with heat-insulating materials so that the overall heat will not be dissipated. The heating zone 2 also includes an exhaust hole 22, which is arranged in the middle of the coil 21. The exhaust hole 22 can be used to discharge excess gas inside the device, thereby avoiding excessive pressure inside the device.

[0033] Reference Figure 2 , Figure 3 and Figure 4 In one aspect of the present embodiment, the superheating zone 3 includes a spiral tube 31 and a water outlet pipe 32. The spiral tube 31 is located inside the outer ring tube 11 and below the coil 21. The top of the spiral tube 31 is connected to the inside of the coil 21, and the sparse winding forms a pagoda-shaped structure. The water outlet pipe 32 is fixed to the bottom of the spiral tube 31 and is connected to the inside of the spiral tube 31. The top of the water outlet pipe 32 passes through the exhaust hole 22. The flame burning inside the outer ring tube 11 can fully heat the water passing through the inside of the spiral tube 31, and the heated water can form superheated steam through the water outlet pipe 32 and be discharged.

[0034] Reference Figure 2 In one aspect of the present embodiment, the outer ring tube 11, the water inlet tube 12, the coil 21, the spiral tube 31 and the water outlet tube 32 are all configured as stainless steel tubes. By configuring the outer ring tube 11, the water inlet tube 12, the coil 21, the spiral tube 31 and the water outlet tube 32 to be formed of stainless steel tubes, the service life of the entire device can be further increased.

[0035] Working principle:

[0036] When using, first Figure 1 , Figure 2 and Figure 3 As shown, the device is manufactured, and water is passed into the interior of the device through the water inlet pipe 12;

[0037] The water entering the water inlet pipe 12 enters the coil 21 through the outer ring pipe 11. At the same time, the combustion zone inside the combustion chamber sprays flames to heat the inside of the equipment. The sprayed flames enter the outer ring pipe 11 to heat the water inside the outer ring pipe 11 and the coil 21. The water entering the coil 21 flows through the spiral tube 31 and heats the spiral tube 31 through the heat retained in the outer ring pipe 11. The heated water enters the water outlet pipe 32 to form superheated steam, which is finally sprayed out through the water outlet pipe 32.

[0038] During the entire heating process, by providing a preheating zone 1 with a tightly wound outer ring tube 11 and a heating zone 2 with a tightly wound coil 21, the combustion chamber flame zone can be sealed so that excess flame will not be lost quickly after flame heating, and the overheating zone 3 can continue to be fully heated, thereby making great use of excess flame and preventing most of the heat from overflowing and causing loss. The energy-saving effect is significantly improved, the utilization rate of the flame is increased, and the waste of resources is avoided, which is beneficial to practical application and operation.
