The present invention relates to an apparatus to circulate unburned gas and headwind of a combustion apparatus. According to an embodiment of the present invention as shown in Fig. 2, Fig. 2 is a drawing of a circulation of unburned gas. When fuel is placed into a combustion chamber and burned, a heat energy inducing plate (3) made of two layers with a certain interval to induce a flow of heat energy on a top of the combustion chamber is heated. The bottom plate of the heat energy inducing plate has a plurality of holes and an empty center. Secondary air serves the role of a flow pipe. The heat energy is combined with the heated secondary air to burn more fiercely to move towards the top of the combustion apparatus. The heat energy discharges a lot of heat on the top of the combustion apparatus, and cools down to become a descending air current. Of the descending heat energy, light heat energy completely burned is discharged through an exhaust hole (5), and the unburned gas passes through the ash tray (8) and the combustion chamber heat plate (9) through a circulation passage (7) to reburn for complete combustion. According to another embodiment of the present invention as shown in Fig. 3, Fig. 3 is a drawing of the circulation of headwind. When a headwind blows, the headwind, which is colder than an internal temperature of the combustion apparatus moves to the circulation passage (7) by blocking the headwind preventing plate (4), passes through the ash tray (8) and the combustion chamber heat plate (9), and circulates. It can maintain a smooth combustion without interfering with combustion. |
