DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] like Figure 1-Figure 4As shown, a high-utilization vertical boiler proposed in an embodiment of the present application is constructed with a water storage chamber 1 and a heating chamber 2, which are vertically distributed in sequence, so that the heat in the heating chamber 2 is guided to the water storage chamber 1 through heat transfer, thereby heating the water in the water storage chamber 1. The heating chamber 2 has a feed port and a smoke exhaust port 3, which are respectively used to place solid fuel inside and exhaust smoke. Based on these, the following parts are also included:

[0023] One end of the air supply pipe 4 is connected to the heating chamber 2, and the air supply component 6 is arranged in the air supply pipe 4. When the air supply component 6 obtains the rotational power, the air flow can enter the air supply pipe 4 under the action of the air supply component 6. Specifically, the air supply component 6 can be a fan blade or other components, such as Figure 3 and Figure 4 As shown;

[0024] The turbine 7 arranged at the smoke exhaust port 3 is rotated and is in transmission connection with the air supply assembly 6, so that when the turbine 7 rotates, the rotational power can be transmitted to the air supply assembly 6;

[0025] Based on the above, when the fuel in the heating chamber 2 is burning, the flue gas will drive the turbine 7 to rotate during the discharge from the smoke exhaust port 3, thereby driving the air supply assembly 6 to rotate, so as to realize the delivery of external air to the heating chamber 2, thereby increasing the oxygen content in the heating chamber 2, so as to promote the complete combustion of the fuel, thereby reducing the carbon deposition in the heating chamber 2, thereby reducing the impact on the heat conduction of the chamber wall, so as to reduce the impact on the heating efficiency. In addition, by reducing the carbon deposition phenomenon, the impact on the life of the entire boiler is reduced, so that the entire boiler has a better utilization rate.

[0026] like Figure 3 and Figure 4 As shown, in some embodiments, the heating chamber 2 may further include a connected heating zone 8 and an extension zone 9, the extension zone 9 passes through the water storage chamber 1, and the smoke exhaust port 3 is located at the end of the extension zone 9. The extension zone 9 can increase the contact area between the water storage zone and the entire heating zone 8 to improve the heat conduction efficiency.

[0027] like Figure 3 and Figure 4As shown, in some embodiments, the whole can also include a shaft 10. Based on this, the extension area 9 can be of a columnar structure. The shaft 10 is arranged to rotate relative to the extension area 9 and remain coaxial therewith. The shaft 10 can be directly rotatably arranged inside the extension area 9, and one end thereof extends to pass through the smoke exhaust port 3 and the air supply duct 4. The turbine 7 is arranged on the shaft 10, thereby completing the rotation installation at the smoke exhaust port 3. The above air supply assembly 6 can be specifically arranged on the shaft 10, thereby completing the installation in the air supply duct 4 and completing the transmission connection with the turbine 7. The heating area 8 is located below the water storage chamber 1. The shaft 10 is connected with a first scraper 11 acting on the cavity wall of the extension area 9 and a second scraper 12 acting on the upper cavity wall of the heating area 8. Therefore, when the shaft 10 rotates driven by the turbine 7, the first scraper 11 and the second scraper 12 rotate synchronously, thereby further reducing the carbon deposition on the cavity wall.

[0028] like Figure 3 and Figure 4 As shown, in some embodiments, the first scraper strip 11 can be spirally constructed, so that when it rotates, the scraped carbon powder can be driven downward by the spiral structure to reduce the phenomenon of being directly carried away by the flue gas, thereby increasing the time it stays inside. When it is hung up, it can be ignited again by the high temperature of the flue gas, thereby generating heat in the extension area 9, thereby increasing the heating effect on the water storage area and reducing carbon waste.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, the heating zone 8 can also include a combustion zone 13 and an air intake zone 14 from top to bottom. The combustion zone 13 and the air intake zone 14 are connected by an air vent 15. The combustion zone 13 is used to place solid fuel and is the concentrated area of ​​the flame. The air vent 15 is spread throughout the entire horizontal plane, so that the air flow can flow up and down normally, and the fuel will not fall directly into the air intake zone 14 below. The above feed port is specifically connected to the combustion zone 13, so that the fuel is placed in the combustion zone 13. The air supply duct 4 is specifically connected to the air intake zone 14. Therefore, when the air enters the interior, the air is squeezed into the upper part, thereby passing through the air vent 15 in the process, so that the air will completely pass through the fuel. Through this structure, the effect of air and fuel contact is further promoted, thereby effectively promoting combustion.

[0030] like Figure 3 and Figure 4 As shown, in some embodiments, the whole may also include an air nozzle 16 disposed in the air intake area 14, which faces the air vent 15. The air nozzle 16 is connected to the air supply duct 4. The air can pass through the local air vent 15 in a directional manner through the air nozzle 16, so that when placing the fuel, the fuel can be placed in the direction of the air nozzle 16 in a targeted manner, thereby further guiding the incoming air to the fuel.

[0031] like Figure 3 and Figure 4 As shown, in some embodiments, there are multiple jet nozzles 16 distributed in a circular array. The multiple jet nozzles 16 are arranged to create a centralized placement for the fuel, so that the airflow is finally blown to one place. In addition, through this design, the airflow formed by the multiple jet nozzles 16 can blow the flame above to surge upward, so that it contacts the cavity wall, so as to better promote the heating of the water storage cavity 1.

[0032] like Figure 3 and Figure 4 As shown, in some embodiments, the air supply pipeline 4 includes an air intake pipe 17 and an air guide pipe 5 connected between the air intake pipe 17 and the air nozzle 16. The air supply assembly 6 is located in the air intake pipe 17. The diameter of the air intake pipe 17 gradually increases from the end away from the air guide pipe 5. This design not only increases the air intake volume, but also makes the air entering the air intake pipe 17 eventually get a squeezing effect, so that the gas finally has a jetting effect when it comes out of the air nozzle 16, so that the ash is not easy to fall into the air nozzle 16.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
