Working Principle:
Fuel is burned in burner to produce high-temperature gas. Hot-blast stove, a reinforced heat-exchanging device, conducts the heat to the air to be heated. After radiating, high-temperature gas reduces to below 250℃, and discharged to the atmosphere by draught fan. The air to be heated was transported to hot-blast stove by fan. After absorbing heat, the temperature rises to rated value and is let out at hot-blast mouth. When the hot-blast temperature reaches to the rated upper limit, the burner will stop to work automatically or turn to small fire. When the hot wind temperature reaches to the rated lower limit, the burner will kindle again or turn to big fire. The temperature rising speed can be adjusted by the switch of air intake valve.

Scope of usage:
Hot wind furnace is used in industrial field, metal surface coating, pharmacy, foodstuff processing, food, wood processing, textile printing and dyeing, chemical industry, and auto industry.
For example: high-temperature solidification after spray molding and spray paint, Chinese herbal medicine drying, foodstuff drying, starch drying, biscuit baking, instant noodles drying, dried noodles drying, transmission belt drier, wood drying, fiber board, multi-layer board drying, printing drying, heat molding, hot wind tentering，chemical industry materials drying, tunnel drying room.
