Product Overview
The Indirect Coal-Fired Hot Air Furnace (also compatible with biomass fuels) is an energy-efficient industrial drying solution designed for a wide range of applications, including daily chemicals, food, pharmaceuticals, building materials, and chemical industries. This advanced heat exchange dryer uses indirect combustion technology to generate clean, high-temperature air for drying without contaminating the product.
With a capacity ranging from 250,000 to 20 million Kcal/h, this hot air dryer delivers reliable performance with stable temperature control (±5°C) and high thermal efficiency, making it ideal for continuous drying processes in industrial environments.
Key Features & Advantages
Indirect Heat Exchange Design
The unit adopts a countercurrent heat exchange system: hot flue gas flows outside the heat exchanger tubes, while clean air flows inside, ensuring high-efficiency heat transfer without contamination.
Coal, Biomass, or Multi-Fuel Compatible
Supports combustion of coal, wood pellets, biomass briquettes, and other solid fuels. The chain grate burner ensures complete and steady combustion with high heat output.
Dust Filtration & Clean Operation
Integrated high-temperature dust purification technology minimizes flue dust, protects the heat exchanger from wear, and ensures clean hot air output, especially important for food or pharmaceutical drying.
Durable, Low Maintenance, and Safe
Features advanced jet technology in the heat exchanger and interposer structure to enhance thermal performance. Designed for long life, with minimal maintenance needs and no explosion risk.
Precise Temperature Control
Hot air temperature is adjustable from 50°C to 600°C. Output remains stable within a narrow ±5°C tolerance, allowing for optimized moisture removal from sensitive materials.
