The Y5-48 Boiler Centrifugal Induced Draft Fan is an industrial centrifugal ID fan designed for boiler flue gas extraction, furnace negative pressure control and continuous exhaust operation.
Installed in the downstream flue gas system, the Y5-48 extracts combustion flue gas from the boiler and provides sufficient pressure to overcome the resistance of dust collectors, flue gas treatment equipment, ducts and chimneys.
The fan is suitable for industrial steam boilers, hot water boilers, biomass boilers, waste heat boilers, district heating systems and other thermal energy applications.
EMS can customize the fan according to airflow, pressure, gas temperature, dust concentration, gas composition, material requirements and installation conditions.

Engineering Note: The above figures are typical reference ranges rather than fixed specifications for every Y5-48 configuration. Final selection should be based on the actual airflow, pressure, gas temperature, gas density, dust concentration and total system resistance.
Boiler Furnace → Dust Collector → FGD / DeNOx → Y5-48 ID Fan → Chimney
Hot flue gas generated during boiler combustion passes through the dust collection and flue gas treatment equipment before entering the Y5-48 induced draft fan.
The centrifugal impeller generates negative pressure at the inlet and continuously extracts flue gas from the boiler system. The fan then increases the gas pressure sufficiently to overcome downstream system resistance and discharge the treated flue gas through the chimney.
Proper ID fan selection helps maintain stable furnace negative pressure and reliable boiler operation.
The Y5-48 is designed for boiler flue gas extraction and negative pressure control in continuous industrial operation.
The centrifugal impeller provides stable airflow and pressure for boiler exhaust systems with significant system resistance.
The fan can be selected according to the pressure losses of dust collectors, FGD, DeNOx and other flue gas treatment equipment.
For dusty flue gas applications, EMS can provide wear-resistant impellers, liners and reinforced structures according to the actual dust characteristics.
For elevated-temperature flue gas, suitable bearings, shaft cooling arrangements, high-temperature materials and sealing systems can be configured.
Depending on power, speed and installation requirements, the fan can be supplied with:
Direct Drive
Belt Drive
Coupling Drive
The Y5-48 can be used in:
Industrial Boiler Plants
Steam Boiler Plants
Biomass Boiler Plants
Waste Heat Boiler Systems
District Heating Plants
CHP Plants
Thermal Energy Facilities
Boiler Dust Collection Systems
Flue Gas Treatment Systems
Industrial Heating Systems
For accurate Y5-48 selection, customers should provide:
Boiler Capacity
Fuel Type
Required Flue Gas Flow
Required Fan Pressure
Gas Temperature
Gas Density
Dust Concentration
Flue Gas Composition
Total System Resistance
Dust Collector Pressure Loss
FGD / DeNOx Pressure Loss
Duct Size and Length
Installation Altitude
Motor Voltage and Frequency
Operating Hours
Material Requirements
Drive Type
Noise Requirements
Boiler capacity alone is not sufficient for fan selection. The actual duty point should be calculated from the flue gas volume and total resistance of the complete boiler exhaust system.
