Its main function is to optimize the utilization of thermal energy, reduce energy consumption and operating costs, and at the same time reduce the environmental burden. It is suitable for industrial and commercial boiler systems.

One end of the coil 2 is fixedly connected to an air inlet pipe 5, and the other end of the coil 2 is fixedly connected to an air outlet pipe 6. The coil 2 is coiled around the outer surface of the heat storage body 1, and one end of it is connected to a steam pipe 11 through the air inlet pipe 5. Steam can be used to heat the liquid inside the heat storage body 1. At the same time, the insulation layer 3 is set on the outer surface of the coil 2, and the protective shell 4 protects the insulation layer 3, thereby reducing its heat loss, ensuring effective heat storage and transfer, reducing heat loss, and improving heat replenishment efficiency.

[0029] The pressure control assembly includes a motor 7, the lower surface of which is fixedly mounted on the upper surface of the accumulator body 1. A threaded rod 8 is fixedly connected to the output end of the motor 7. A sealing plug 9 is threadedly connected to the outer surface of the threaded rod 8. A protrusion 10 is fixedly connected to the outer surface of the sealing plug 9. When the motor 7 is started by an external power source, it drives the threaded rod 8 to rotate. The sealing plug 9 moves up and down under the limiting and guiding action of the protrusion 10. The sealing plug 9 applies pressure to the inside of the accumulator body 1 to increase its internal temperature, thereby improving the thermal energy storage capacity of the accumulator body 1 so as to provide more efficient heat release when needed, and thus improve the overall thermal efficiency of the boiler.

[0030] One end of the air inlet pipe 5 is fixedly connected to a steam pipe 11, and the lower surface of the steam pipe 11 is fixedly connected to the boiler body 12. The steam pipe 11 concentrates the heat generated inside the boiler body 12 so that steam can enter the heat accumulator body 1.

[0031] A burner 13 is fixedly installed on one side of the boiler body 12, and smoke boxes 14 are fixedly connected to both sides of the inner wall of the boiler body 12. Starting the burner 13 can heat the liquid inside the boiler body 12. The smoke box 14 facilitates the backflow of the flue gas generated during combustion, which then flows into the smoke pipe 15.

[0032] A flue pipe 15 is fixedly connected to the upper part of the inner side of the smoke box 14, and a furnace 16 is fixedly connected to the bottom of the inner side of the smoke box 14. The opening at one end of the furnace 16 corresponds to the combustion end of the burner 13. The flue pipe 15 can increase the heat exchange area and transfer the heat in the flue gas to the liquid inside the boiler body 12 for heating, so as to reduce heat loss and improve energy utilization efficiency.

The third pipe 21 facilitates the replenishment of water to the inside of the heat accumulator body 1.

[0035] Working steps: First, the burner 13 heats the liquid inside the boiler body 12. The smoke box 14 facilitates the return flow of the flue gas generated during combustion, which then flows into the smoke pipe 15. The smoke pipe 15 increases the heat exchange area, transferring the heat from the flue gas to the liquid inside the boiler body 12 for heating, and also discharges the flue gas. Next, the heat generated inside the boiler body 12 flows upward to form steam, which enters the accumulator body 1 through the steam pipe 11 and the air inlet pipe 5. Then, the coil 2 is wound around the outer surface of the accumulator body 1, and the steam heats the liquid inside the accumulator body 1. At the same time, the insulation layer 3 is set on the outer surface of the coil 2, and the protective shell 4 protects the insulation layer 3. Finally, the motor 7 can be started by an external power source to drive the threaded rod 8 to rotate. The sealing plug 9 moves up and down under the limiting and guiding action of the protrusion 10, and the sealing plug 9 applies pressure to the inside of the accumulator body 1 to increase its internal temperature. Subsequently, the first pipe 19 and the second pipe 20 can both supply heat to the inside of the boiler body 12.
