Air enters the second air passage 622 from the air inlet 621, and the air in the second air passage 622 is heated by heat transfer due to the high residual temperature of the flue gas flowing in the flue gas passage 623, and then the heated air enters the combustion chamber 611 through the first air passage 612 to meet the combustion temperature. From this, the embodiment of the present application further improves the fuel utilization rate through the gas heat exchanger 620, and is beneficial to improving the heating efficiency of the lubricating oil and shortening the heating time.

A flue gas channel 623 is formed in the heat exchange pipeline 626, and a second air channel 622 is formed between the heat exchange pipeline 626 and the shell 625 so as to facilitate heat diffusion and improve heating efficiency; also, since the first air passage 612 is located outside the combustion chamber 611, the second air passage 622 is formed between the heat exchanging pipe 626 and the housing 625, facilitating the arrangement of the flue gas passage 623, and the second air passage 622 communicates with the first air passage 612.
Optionally, the oil transportation branch pipe 300 has an oil inlet end 320 and an oil outlet end 330, and the oil inlet end 320 and the oil outlet end 330 are respectively disposed on two sides of the burner 610, so as to facilitate the arrangement of the oil transportation branch pipe 300.

Alternatively, the outer peripheral surface of the heat exchanging pipe 626 may be a smooth surface, in which case the contact area of the outer peripheral surface with air is small; therefore, further alternatively, the outer circumferential surface of the heat exchanging pipe 626 is provided with the second spiral fin 626c, so that the contact area of the heat exchanging pipe 626 with the air in the second air passage 622 is increased, thereby further improving the heating efficiency of the air.

Further alternatively, the top cover of the cyclone 615 is provided with a through hole so as to facilitate the cooling air to be introduced according to actual needs to meet the combustion needs.
The number of heat exchanging pipes 626 may be one or at least two, and when the number of heat exchanging pipes 626 is one, the cross-sectional area of the heat exchanging pipe 626 needs to be set larger to meet the requirement of flue gas exhaust of the combustion chamber 611, however, the space occupied by the heat exchanging pipe 626 is larger, resulting in smaller space of the second air channel 622 and lower heating efficiency of air. Optionally, the number of the heat exchange tubes 626 is at least two, and each heat exchange tube 626 is disposed at intervals, so that the occupied space of the heat exchange tube 626 is reduced, the space of the second air channel 622 is increased, and the total area of the outer peripheral surfaces of the plurality of heat exchange tubes 626 is larger, which is beneficial to accelerating the heating efficiency of air.

In an alternative embodiment, the heat exchange tubes 626 include a first heat exchange tube 626a and a second heat exchange tube 626b, where the cross-sectional area of the first heat exchange tube 626a may be equal to the cross-sectional area of the second heat exchange tube 626b, the central axis of the first heat exchange tube 626a coincides with the central axis of the inner tube 613, and the plurality of second heat exchange tubes 626b are arranged at intervals along the circumference of the first heat exchange tube 626a, and since the heat is spread out from the outer circumference of the heat exchange tube 626, the heat will collect in the central area of the housing 625, and the area close to the housing 625 has less heat, resulting in uneven air heating. Based on this, the cross-sectional area of the first heat exchanging pipe 626a is optionally larger than that of the second heat exchanging pipe 626b, thereby preventing heat from being concentrated in the central region of the housing 625 and thus improving uniformity of air heating.
In an alternative embodiment, first tube segment 310 is a spiral tube, thereby increasing the size of first tube segment 310 to accommodate more lubrication oil, thereby increasing the heating efficiency of the lubrication oil; also, the first pipe section 310 is a spiral pipe, which can improve the compactness of the first pipe section 310 to be accommodated in the combustion chamber 611, thereby improving the space utilization of the combustion chamber 611.
