What Is a High-Temperature Hot-Air Duct Furnace?
A high-temperature hot-air duct furnace is a direct-fired heating unit that burns coal to generate high-temperature hot air and delivers it through air ducts to industrial drying and heating systems. It works as the heat source of rotary dryers: the furnace heats the air, the fan pushes the hot air into the dryer drum, and the material is dried as it passes through the rotating drum. The TZF Series furnace is commonly combined with three-drum rotary dryers to dry sand, slag, and other granular materials in aggregate and mineral processing lines.
Applications
- Heat source for three-drum rotary dryers drying sand, slag and mineral aggregates
- High-temperature hot-air supply for industrial drying and heating processes
- Coal-fired heating for rotary dryer systems in aggregate and mineral processing plants
- Drying support in cement, building-material, mining and beneficiation lines
