Heat source : Natural Gas
Airflow direction: External fresh air enters the furnace body through circumferential inlet slots on the front end face .Then extracted from the other side and directed into the drying room
Matching :Drying Rooms、Beds
Features : Direct fired structure for high thermal efficiency and low heat loss|Negative pressure,radial slot and air intake cools cylinder to prolong service life
1. Simple structure and easy installation.
2. Small air volume, high temperature, adjustable from normal temperature to 500℃.
3. Stainless steel high temperature resistant inner tank, durable.
4. Automatic gas burner, complete combustion, high efficiency. (After setting up, the system can control the ignition+cease fire+temperature adjust automatic).
5. The fresh air has a long stroke that can fully cool the inner tank, so the outer tank can be touched without insulation.
6. Equipped with high temperature resistant centrifugal fan, large pressure center and long lift.
7. Applications:
- Vegetable, flower, and other planting greenhouses
- Poultry and livestock breeding warm houses (chicks, ducks, pigs, cattle, etc.)
- Heating for workshops, shopping malls, and mining sites
- Powder coating, sandblasting, and paint baking rooms
- Rapid curing of concrete pavements
1. TL4 Natural Gas Direct‑fired hot blast furnace consists of fresh air inlet, gas burner, fixed support, inner cylinder, flame retardant board, middle cylinder, outer cylinder and hot air outlet.
2. Fresh air enters from the fresh air inlet and flows through gaps between multi‑layer cylinders.
3. The gas burner ignites inside the inner cylinder to produce high‑temperature flue gas.
4. The flame retardant board stabilizes flame and promotes full mixing of high‑temperature gas and fresh air in the mixing zone.
5. Mixed hot air is discharged through the hot air outlet for drying process.
6. Multi‑layer cylinder structure reduces surface temperature and ensures stable output of hot air.
