Oil Gas Hot Air Generator | Hot Air Heater Boiler

It is widely used in industries such as grain, fertilizer, chemical, printing and dyeing, vegetable dehydration, residue drying and mine heating.

Direct type & Indirect type Hot Air Furnace 

1. Direct type gas hot air furnace

It is to use fuel to burn directly, to form hot air after high purification treatment, and to directly contact with the material to heat and dry or bake. The high-temperature combustion gas obtained after the combustion reaction of the fuel is further contacted with the outside air, mixed to a certain temperature, and directly enters the drying room or baking room, where it contacts with the material to be dried, heats and evaporates moisture, thereby obtaining a dry product.

2. Indirect type gas hot air furnace

It is mainly suitable for drying materials that are not allowed to be contaminated, or drying of heat-sensitive materials with low temperature. Such as: milk powder, pharmaceuticals, synthetic resins, fine chemicals, etc. This kind of heating device uses steam, heat transfer oil, flue gas, etc. as the carrier to heat the air through various forms of heat exchangers. The most essential problem of indirect hot blast stove is heat exchange. The larger the heat exchange area, the higher the heat transfer rate, the better the energy saving effect of the hot blast stove, and the longer the life of the furnace body and heat exchanger. Conversely, the size of the heat exchange area can also be identified from the flue gas temperature. The lower the smoke temperature, the higher the heat transfer rate and the larger the heat exchange area.
