However, under the requirements of modern high efficiency and energy conservation, the traditional open fire heat supply mode has gradually revealed the limitation. Along with the rising of energy price and the enhancement of environmental awareness, the improvement of energy utilization efficiency becomes a problem to be solved urgently.
In order to increase energy utilization, various methods are generally employed to optimize the combustion process. For example, a heat conducting member, such as a flame guiding groove or a protruding structure, may be provided at the bottom of the pan to increase the contact area of the pan body with the flame, thereby more effectively absorbing heat. Another common approach is to modify the design of the burner so that it produces a more uniform and efficient flame, reducing heat dissipation.

The middle of the smoke exhaust pipe 2 is located inside the container and the end extends to the outside of the container to serve as a smoke exhaust port 22. Therefore, after the fuel is fully combusted in the combustion tube 1, the generated exhaust gas enters the smoke exhaust tube 2 through the connecting tube 21, and the smoke exhaust tube 2 can heat substances in the container because the exhaust gas still has high heat, so that the full utilization of the energy of the exhaust gas is realized.
The connecting pipe 21 and the combustion pipe 1 and the connecting pipe 21 and the smoke exhaust pipe 2 are obliquely arranged, one end of the connecting pipe 21 connected with the combustion pipe 1 is far away from the smoke outlet 22, and one end of the connecting pipe 21 connected with the smoke exhaust pipe 2 is close to the smoke outlet 22.

The exhaust gas can be discharged by the exhaust port 22 under the guiding effect of the connecting pipe 21, the gas flow rate in the smoke exhaust pipe 2 is faster, and the interior of the smoke exhaust pipe 2 is an open environment, the temperature is higher, so that the air pressure in the smoke exhaust pipe 2 is lower, and the air outside the smoke exhaust pipe 2 can enter through the air inlet 23, so that on one hand, the oxygen content in the smoke exhaust pipe 2 and the combustion pipe 1 can be improved, the combustion sufficiency is improved, and on the other hand, the gas flow efficiency in the smoke exhaust pipe 2 can be improved, and the auxiliary smoke exhaust is realized.
In addition, a blower device, such as a blower, can be additionally arranged at the air inlet 23, and the air inlet 23 is connected with the blower device, so that the blower device can actively supply air into the smoke exhaust pipe 2, thereby improving the air flow efficiency in the smoke exhaust pipe 2 and ensuring the sufficiency of fuel combustion. However, it is considered that the air supply speed and the air supply amount of the blower are not easily excessively large, which would cause the heat in the smoke exhaust pipe 2 to be rapidly exhausted through the smoke exhaust port 22, thereby affecting the heat efficiency.
According to the application, through the structural design of the smoke exhaust pipe 2 and the combustion pipe 1, the full utilization of the energy of the waste gas is realized, so that the thermal efficiency is improved.

On the other hand, the combustion chamber 11 has a large surface area, and heat exchange efficiency can be improved. In addition, the connection between the connection pipe 21 and the combustion chamber 11 can improve the efficiency of exhaust smoke, and after the oxygen-containing air enters the inside of the smoke exhaust pipe 2, the fuel which is partially insufficiently combusted can be continuously combusted, so that the utilization efficiency of the fuel can be improved.
In the embodiment of the application, the combustion chamber 11 can be arranged in a spherical shape, a square shape or a cylindrical shape, and can be flexibly designed according to practical requirements.
