Key Types of Centrifugal Blowers for Power Plants & Boilers
1. Forced Draft (FD) Fan
Supplies combustion air to the boiler furnace. Handles clean air at ambient temperature. High volume, medium pressure. Mounted before the air preheater. Critical for efficient combustion.
2. Induced Draft (ID) Fan
Extracts flue gases from the boiler and pushes them through pollution control equipment (ESP, bag filter) and chimney. Handles hot, abrasive, dusty flue gases at 150-300°C. Most demanding application requiring abrasion-resistant and high-temperature design.
3. Primary Air (PA) Fan
Supplies high-pressure air to the coal pulverizers for drying and transporting pulverized coal to the burner. Handles clean, moderately hot air. High pressure application.
4. Secondary Air Fan
Supplies additional combustion air to ensure complete burning. Similar to FD fan but may have different pressure requirements. Mounted after the air preheater in some configurations.
Applications Across Boiler Types
- Coal-Fired Boilers (Pulverized Coal, Spreader Stoker, Chain Grate, Fluidized Bed Combustion – FBC, Atmospheric Fluidized Bed Combustion – AFBC, Circulating Fluidized Bed Combustion – CFBC)

Frequently Asked Questions – Centrifugal Blowers for Power Plants & Boilers
1. What CFM is required for a 100 TPH boiler FD fan?
A 100 TPH boiler typically requires approximately 30,000-40,000 CFM FD fan capacity. The exact requirement depends on fuel type (coal, biomass, petcoke), excess air ratio, and boiler design. Our team can calculate precisely based on your boiler specifications.
2. What is the typical operating temperature for an ID fan?
ID fan inlet temperature typically ranges from 150-250°C for coal-fired boilers (after air preheater) and can go up to 300°C. For biomass boilers, temperatures may be similar. Our ID fans are designed with water-cooled bearings and high-temperature grease for reliable operation.
3. Do you offer VFD-controlled fans for power plants?
Yes. We supply centrifugal blowers with VFD (Variable Frequency Drive) compatibility or integrated VFD panels. VFD control allows significant energy savings (15-30%) by matching fan speed to actual boiler load, especially for FD and PA fans.
4. What is the difference between FD fan and ID fan?
FD Fan (Forced Draft) pushes ambient air into the boiler for combustion – it handles clean, cool air. ID Fan (Induced Draft) pulls hot flue gases out of the boiler and pushes them to the chimney – it handles hot, dusty, abrasive flue gases. ID fans require abrasion-resistant construction and high-temperature bearings.
