AIRFORCE
Biomass Fired Hot Air Generator
The AIRFORCE Series is a robust, horizontal multi-pass direct-fired hot air generator engineered for high-demand industrial drying and processing. Utilizing advanced Fluidized Bed Combustion (FBC) technology, the AIRFORCE is a pioneer in fuel flexibility, allowing industries to generate high-temperature process air using a variety of cost-effective, free-flowing biomass fuels.
Designed for maximum thermal efficiency, the AIRFORCE system provides a stable, high-heat output of up to 600°C without the complexities and risks of high-pressure boiler systems.
Operating Range
- Capacity – 0.4 million kcal/hr. to 10 million kcal/hr.
- Fuel- Saw dust, rice husk, pulverizes coal
- Temperature- up to 600 ºC
Advanced Combustion & Automation
The AIRFORCE series is built for seamless operation and consistent thermal performance:
- FBC Technology: The fluidized bed combustion process ensures complete burnout of even low-calorific fuels, resulting in higher thermal efficiency and lower emissions.
- Fuel Flexibility: Specifically designed to fire free-flowing fuels such as sawdust, rice husk, and pulverized coal, allowing you to switch fuels based on market availability.
- Automated Fuel Feeding: Equipped with an advanced Screw Feeding System managed by an A.C. Drive. This allows for precise, automated control over the fuel-to-air ratio, maintaining a constant output temperature.
- Horizontal Multi-Pass Design: The multi-pass configuration optimizes the contact time between the hot gases and the heat exchanger, ensuring maximum heat recovery before exhaust.
Key Features
- High-Temperature Output: Capable of delivering clean hot air up to 600°C, ideal for heavy-duty industrial drying.
- Zero Operating Pressure: Unlike steam systems, the AIRFORCE operates at atmospheric pressure, eliminating the need for high-pressure vessel certifications and increasing plant safety.
- Low Operational Cost: By utilizing biomass waste (husk/sawdust), the system significantly reduces fuel expenses compared to oil or gas-fired alternatives.
Industry Applications
The AIRFORCE Series is the ideal thermal solution for large-scale industrial drying and processing:
- Chemical & Fertilizer: For spray dryers and rotary dryers requiring high-temperature air.
- Agriculture & Grain: Large-scale drying of paddy, parboiled rice, and various seed crops.
- Cement & Minerals: For moisture removal in raw materials and specialized kiln applications.
- Paper & Pulp: High-volume air heating for paper drying sections.
- Food Processing: Large-scale dehydration of vegetables, spices, and starch products.
Frequently Asked Questions (FAQ) about Biomass Fired Hot Air Generator
FBC technology suspends fuel particles in a hot, bubbling bed of sand or ash using an upward flow of air. This ensures a very high rate of heat transfer and uniform temperatures, allowing the system to burn low-grade biomass fuels very efficiently.
Yes, the system is designed for "Free Flow" fuels. As long as the fuel is properly sized and free-flowing (like rice husk or sawdust), the automated screw feeder can manage the input to maintain consistent heat.
No. One of the primary benefits of the AIRFORCE Hot Air Generator is that it delivers high process temperatures (up to 600°C) at atmospheric pressure, making it safer and easier to operate than a high-pressure steam boiler.
The temperature is managed through an integrated A.C. Drive that controls the speed of the screw feeder. By automatically adjusting the fuel flow based on the desired temperature set-point, the system maintains high thermal precision.
While the AIRFORCE is a direct-fired system, the high-efficiency FBC combustion ensures a very clean burn. For sensitive food applications, we can also provide indirect-fired options where the combustion gases do not mix with the process air.
