The material of the heat exchange coil 300 is set to metal copper, which has a good thermal conductivity effect.

[0026] Example 2: Figure 3 The bottom side wall of the combustion chamber 100 is evenly provided with air inlet holes 150, which are arc-shaped. The angle between the air inlet holes 150 and the inner wall of the combustion chamber 100 is set to 45°.
