Indirect Hot Air Furnace:
The indirect hot air furnace produced by our company is an energy-saving hot air furnace specially designed for supporting drying systems. It transfers heat to clean air through flue gas, and is mainly suitable for drying materials that are not allowed to be contaminated or for drying heat-sensitive materials requiring lower hot air temperatures. It can provide clean hot air at different temperatures.
Application Fields:
The indirect coal-fired hot air furnace is a universal hot air device, used in conjunction with drying equipment for various materials. It is widely used for heating and dehumidifying agricultural products such as grain, seeds, feed, fruits, dehydrated vegetables, shiitake mushrooms, wood ear mushrooms, white fungus, tea, and tobacco leaves, as well as food, pharmaceuticals, chemical raw materials, and light and heavy industrial products. It can also be used for heating various facilities and dehumidifying warehouses.
Performance Features:
1. Clean hot air, no pollution.
2. Rapid temperature rise, stable hot air temperature, low maintenance cost.
3. Reasonable flue gas and air flow paths. Heat exchange adopts a counter-flow method: flue gas flows outside the tubes while air flows inside the tubes, enhancing heat transfer.
4. Thermal efficiency >75%, hot air temperature stability ±5℃.
5. Wide range of fuel options: fuel oil, gas, and pulverized coal are all acceptable.
6. Simple equipment operation.
