One end of the exhaust component is connected to the inner shell 22, and the other end extends out of the outer shell 21 and the housing 1. Compared with the prior art, the flue gas furnace mainly consists of a combustion furnace, an igniter, a gas supply device, and a smoke exhaust device. An igniter is installed on the combustion furnace. The gas supply device conveys oxygen or air into the combustion furnace. The flue gas generated by the combustion furnace is discharged from the smoke exhaust device. Moreover, in order to reduce heat consumption, an insulating layer is usually arranged outside the combustion furnace to isolate heat. However, the existing flue gas furnace needs to be insulated through the insulating layer to ensure the temperature inside the combustion furnace. However, the temperature of the air or oxygen entering the combustion furnace is relatively low, and a large amount of fuel is required to heat the air or oxygen, resulting in an increase in fuel consumption, not only wasting resources but also causing the temperature of the generated flue gas to be unstable, thus affecting the subsequent drying process. In this technical solution, by arranging the air inlet channel 23 between the inner shell 22 and the outer shell 21, the gas source component 31 generates air and conveys it into the air inlet channel 23 through the gas supply pipeline 32, so that the air is heated by the temperature generated by the inner shell 22. Then, a part of the air enters the burner 24 to form combustion-supporting air, and another part of the air forms combustion-supporting air through the air inlet channel 23 and the air supply valve 25 and enters the inner shell 22 to assist combustion.

Then, it enters the burner 24 and the air supply valve 25 respectively to form atomized air and combustion-supporting air. The combustion-supporting air enters the inner shell 22 through the air supply valve 25 to assist combustion. By adjusting the damper opening of the gas source component 31, the amount of combustion-supporting air can be adjusted, so that the ratio of the fuel amount to the combustion-supporting air amount is accurate. In the burner 24, the atomized air and the fuel gas are mixed twice.
