The outside of the economizer 4 is also provided with an insulation layer 6 for preventing the loss of heat energy. The furnace body 1 also includes a pipe 1 7 and a pipe 2 8. The pipe 1 7 is used to allow the medium to flow from the economizer 4 to the interlayer chamber 3. One end of the pipe 1 7 is connected to the economizer 4, and the other end is connected to the interlayer chamber 3. The pipe 2 8 is used to allow the medium to flow from the interlayer chamber 3 to the coil 2. One end of the pipe 2 8 is connected to the connecting port 1 21, and the other end is connected to the interlayer chamber 3. In the present embodiment, the medium is an organic heat carrier, such as heat transfer oil.

[0026] The furnace body 1 is also provided with an insulating interlayer 5, which is arranged on the outside of the interlayer chamber 3. The insulating interlayer 5 is used to reduce the loss of heat energy transmitted from the heating source to the coil 2. The insulating interlayer 5 separates the interlayer chamber 3 and the economizer 4, reducing the loss of heat energy transmitted from the heating source to the coil 2.

[0027] The furnace body 1 is also provided with a fuel inlet 10 and a smoke chamber 9. The fuel inlet 10 is used to allow the fuel to pass through. The smoke chamber 9 is used to accommodate the hot smoke generated by the heating source and transfer the hot smoke to the economizer 4. The smoke chamber 9 includes a smoke exhaust channel 91. The smoke exhaust channel 91 is connected to the economizer 4, and the smoke exhaust channel 91 is also connected to the smoke chamber 9.

[0028] The fuel passes through the fuel inlet 10 and supplies energy to the heating source. The heating source heats the coil 2 to generate hot flue gas. The flue gas chamber 9 accommodates the hot flue gas generated by the heating source and transfers the hot flue gas to the economizer 4 through the smoke exhaust channel 91, so that the economizer 4 can preheat the medium in the economizer 4.

[0029] The coil 2 is arranged in a spiral shape. The coil 2 is used to accommodate the medium and transfer heat energy to the medium. In this embodiment, the coil 2 is arranged in two spiral shapes so that the medium is heated. The coil 2 is provided with a connection port 1 21 and a connection port 2 22. The connection port 1 21 is for the medium to enter the coil 2, and the connection port 2 22 is for the medium to flow out of the coil 2. The horizontal height of the connection port 1 21 is higher than the horizontal height of the connection port 2 22.

[0030] The interlayer chamber 3 is used to accommodate the medium. The interlayer chamber 3 allows the medium to flow to the coil 2 through the connecting port 21, and the outer surface of the interlayer chamber 3 is close to the coil 2. The interlayer chamber 3 is used to absorb the heat of the furnace body 1 and transfer the heat energy to the medium in the interlayer chamber 3.

[0031] After preliminary preheating, the medium flows from pipe 1 7 to interlayer chamber 3, interlayer chamber 3 absorbs the heat of furnace body 1 and further preheats the medium in interlayer chamber 3, and the preheated medium flows to coil 2 through connection port 1 21, coil 2 accommodates the medium and coil 2 is arranged in a double-layer spiral so that the heating area is larger, so that coil 2 can transfer heat energy to the medium more fully, and the heated medium is discharged from connection port 2 22, and the horizontal height of connection port 1 21 is higher than the horizontal height of connection port 2 22, so that the medium rotates and flows from top to bottom in coil 2 of furnace body 1, and impurities in the medium are taken out under the action of flow velocity and gravity, thereby improving the purity of the medium in the furnace and extending the life of furnace body 1.

[0032] The implementation principle of this embodiment is as follows: the medium first enters the economizer 4, and after preliminary preheating in the economizer 4, flows to the interlayer chamber 3 in the furnace body 1, and after further preheating in the interlayer chamber 3, flows to the pipe 2 8, and the pipe 2 8 flows to the coil 2 through the connection port 1 21, and the coil 2 transfers the heat energy to the medium, and the heated medium is output from the connection port 2 22, so that the medium is continuously heated through the economizer 4, the interlayer chamber 3 and the coil 2, and the heat energy is fully utilized, thereby improving the thermal efficiency. The horizontal height of the connection port 1 21 is higher than the horizontal height of the connection port 2 22, so that the heated medium rotates down from the coil 2 of the furnace body 1, and under the action of flow velocity and gravity, impurities in the heat carrier can be taken out and the impurities are prevented from adhering to the tube wall, thereby improving the purity of the medium in the furnace and extending the life of the furnace body 1.
