A hot air furnace burner is a device used to heat air and is widely used in various industries. Here are some common hot air furnace burners:

Direct high purification hot air furnace: this burner uses the direct combustion of fuel, after high purification treatment to form hot air, and directly contact with materials for heating, drying or baking.

Indirect Hot Blast Stove: The most fundamental issue with an indirect hot blast stove is heat exchange. The larger the heat exchange area, the higher the thermal conversion rate, and the better the energy-saving effect of the hot blast stove, extending the life of both the furnace and the heat exchanger. Conversely, the size of the heat exchange area can also be identified by the flue gas temperature. The lower the flue gas temperature, the higher the thermal conversion rate, and the larger the heat exchange area.

Gas mixed wind heat furnace: This is a mobile heat source heating boiler, suitable for a variety of occasions.

Direct-fired gas hot air furnace: Conventional gas hot air furnace is divided into two types: indirect hot air furnace, also known as pure wind hot air furnace: a hot air furnace in which the heat exchanger inside the boiler sends the air from the blower to the furnace cylinder for indirect heating through fins is called an indirect hot air furnace.

These are some common types of hot air furnace burners and their working principles. When choosing the right burner, you need to consider specific use scenarios, heat requirements, environmental requirements and other factors.
