Biomass Boiler Fan Selection Guide
Biomass boiler fan selection should consider fuel type, combustion air demand, flue gas volume, pressure, temperature, ash dust, moisture, corrosion, furnace pressure control, and emission equipment resistance. Common fans include ID fans, FD fans, primary air fans, and secondary air fans.
Common Biomass Boiler Fans
- Induced draft fan
- Forced draft fan
- Primary air fan
- Secondary air fan
- Recirculation fan
- High temperature flue gas fan
Fuel Conditions
Biomass fuel may include wood chips, palm shell, rice husk, bagasse, straw, or other organic materials. Fuel moisture and ash content affect combustion air demand and flue gas dust conditions.
Selection Parameters
- Boiler capacity
- Fuel type
- Airflow
- Pressure
- Flue gas temperature
- Ash dust content
- Downstream equipment resistance
- Material and wear requirement
