FAQ – Hot Air Furnace / Hot Air Generator for Industrial Drying
Q1: What types of fuel can be used with this hot air furnace?
A: This hot air furnace supports multiple fuel options including coal, biomass, oil, and gas. You can choose the fuel type based on availability, cost efficiency, and environmental considerations.
Q2: Is this furnace suitable for high-temperature drying applications?
A: Yes. The hot air temperature is adjustable up to 900°C, with a tolerance of ±5°C, making it suitable for high-precision drying processes across industries like chemicals, feed, ceramics, and fertilizers.
Q3: How energy-efficient is the furnace?
A: The system offers a thermal efficiency greater than 95%. It uses a combustion and mixing chamber design to maximize heat transfer while minimizing energy loss and fuel consumption.
Q4: What industries can use this hot air generator?
A: This unit is widely used in daily chemical, ceramics, fertilizer, feedstuff, building materials, drying houses, and spray drying towers.
Q5: Does the furnace meet environmental standards?
A: Yes. The system provides complete combustion with low emissions. Dust content in the hot air is as low as 25–120 mg/Nm³, meeting environmental protection standards.
Q6: How is temperature controlled?
A: The furnace is equipped with frequency conversion control and an intelligent monitoring system. Temperature can be easily adjusted and maintained within a small fluctuation range.
Q7: What is the difference between direct and indirect heating options?
A:Direct heating sends hot air generated from combustion directly into the dryer.
Indirect heating uses a heat exchanger to transfer clean, smokeless hot air into the drying chamber-ideal for food, pharma, or sensitive products.
Q8: What support is provided after purchase?
A: We offer engineer-guided installation, commissioning, and training. After-sales support includes online service, spare parts supply, and field maintenance.
