[0029] Air can be introduced into the combustion chamber in the boiler shell 2 by the turbo pump 4, and heat can be transferred to the water tank 3 through the furnace to heat the water in the water tank 3. The combined boiler can directly heat the water tank 3, reducing heat loss.

[0030] The exhaust pipe 5 is located on the left side of the boiler shell 2. A filter 6 is installed on the left side of the upper surface of the base 1. A conveying pipe 7 is provided on the surface of the filter 6.

[0031] Heating box 8 is located on the front of boiler shell 2. Please refer to [link / reference]. Figure 3 The inner wall of the heating box 8 is provided with a heating groove 9. Please refer to [link / reference]. Figure 2 The right side of the heating box 8 is equipped with a first air outlet pipe 10, and the air outlet end of the first air outlet pipe 10 is connected to the air inlet end of the turbine pump 4.

[0032] The second exhaust pipe 11 is located on the upper surface of the heating chamber 8. Please refer to [link / reference]. Figure 1 The surface of the water tank 3 is provided with a heat insulation shell 12, which is a hollow design. The outlet end of the second vent pipe 11 is connected to the inner cavity of the heat insulation shell 12.

[0033] The exhaust gas from the boiler shell 2 is transported to the filter 6 through the exhaust pipe 5, and then enters the heating tank 9 to heat the air inside the heating box 8. The hot gas recovered in the heating tank 9 enters the insulation shell 12 through the second exhaust pipe 11 to heat and insulate the water tank 3. The turbine pump 4 can draw the heated air from the heating box 8 into the combustion chamber through the first exhaust pipe 10, which does not easily cause the overall temperature in the combustion chamber to drop, thus preventing the fuel combustion speed from slowing down and improving the boiler's combustion efficiency. The combination of the heating box 8 and the insulation shell 12 can reduce the amount of fuel burned and improve the boiler's energy-saving effect.

[0034] Bolts 13 are screwed onto both the front and back sides of the heat insulation shell 12. The bolts 13 are screwed onto the surface of the water tank 3, and the heat insulation shell 12 can be fixed to the surface of the water tank 3 by means of the bolts 13.

[0035] The upper surface of the insulation shell 12 is arc-shaped, which can effectively reduce heat conduction and reduce the temperature difference between the inside and outside of the water tank 3. An exhaust pipe 14 is installed on the surface of the insulation shell 12, through which the gas inside the insulation shell 12 can be discharged.

[0036] The outlet of exhaust pipe 5 is connected to the interior of filter 6. Please refer to [link / reference]. Figure 2 A first air pump 15 is installed on the left side of the filter 6. The first air pump 15 is connected to the delivery pipe 7. A second air pump 16 is installed between the heating box 8 and the second air outlet pipe 11. Starting the first air pump 15 can deliver the gas filtered in the filter 6 to the heating tank 9. Starting the second air pump 16 can deliver the gas in the heating tank 9 to the heat insulation shell 12.

Figure 4 The surface of the air intake pipe 17 is provided with a filter frame 18, and a filter screen 19 is installed on the surface of the filter frame 18. Air can be delivered to the heating box 8 through the air intake pipe 17, and impurities in the air can be filtered by the filter screen 19.

[0038] A flange 20 is mounted on the surface of the air intake pipe 17. A threaded rod 21 is screwed between the flange 20 and the filter frame 18. The filter frame 18 can be disassembled by removing the threaded rod 21, which makes it convenient to clean the filter screen 19.

[0039] The working process of this device is as follows: First, the exhaust gas in the boiler shell 2 is transported to the filter 6 through the exhaust pipe 5. The first air pump 15 is started to transport the filtered gas in the filter 6 to the heating tank 9. The hot gas in the heating tank 9 will heat the air inside the heating box 8. Then, the second air pump 16 is started to transport the gas in the heating tank 9 to the insulation shell 12 to heat and insulate the water tank 3. The turbine pump 4 can draw the heated air in the heating box 8 into the combustion chamber through the first exhaust pipe 10, which is less likely to cause the overall temperature in the combustion chamber to drop, and thus will not slow down the fuel combustion speed, thereby improving the combustion efficiency of the boiler. The heating box 8 and the insulation shell 12 work together to reduce the amount of fuel burned, thereby improving the energy-saving effect of the boiler. Finally, air is transported into the heating box 8 through the air inlet pipe 17. The filter screen 19 is used to filter impurities in the air. The threaded rod 21 can be removed to disassemble the filter frame 18, thereby facilitating the cleaning of the filter screen 19.
