Y6-30 is used as a boiler induced draft fan for extracting flue gas and supporting stable negative pressure on the exhaust side of industrial boiler systems.
This page focuses on Y6-30 application and selection logic: where the fan works in the boiler exhaust route, what project data must be checked, and how induced-draft duty differs from forced-draft duty.
Detailed performance and dimensional data should be taken from verified technical documentation and the actual operating point rather than inferred from the generic Y6-30 name.
Where Y6-30 Works in the Boiler Exhaust Route
The Y6-30 works on the exhaust side of the boiler system. Its job is to draw flue gas through the boiler body, ductwork and dust-removal equipment, then support stable discharge toward the chimney.
The fan must overcome the combined resistance of the boiler body, flue duct, dust collector, dampers and chimney route. This is why motor power or boiler tonnage alone is not enough for final selection.
View Boiler Induced Draft System →Boiler Furnace
Combustion gas is generated.
Flue Duct
Ductwork adds resistance.
Dust Collector
Dust-removal equipment adds pressure loss.
Y6-30 ID Fan
Provides induced draft and negative pressure.
Chimney
Flue gas is discharged.
Verified Y6-30-12 Technical Data Is Published Separately
The original manual available to us is titled Y6-30-12 and provides verified performance, motor, dimensional and installation data for No.3.5C through No.8.6C. Those technical values are kept on the Y6-30-12 page rather than being generalized to every product that may be referred to simply as Y6-30.
The Y6-30-12 page carries the original-manual performance range, motor references and engineering dimensions. Use it when you need verified technical data rather than generic Y6-30 selection guidance.
Before Selecting a Y6-30 Boiler ID Fan
Boiler Duty
Boiler capacity, fuel type, operating load and required induced draft.
Airflow and Pressure
Required airflow and total/static pressure at the same duty point.
Flue Gas Condition
Temperature, dust, moisture, ash abrasiveness and corrosive components.
Dust Collector Resistance
Cyclone, bag filter, wet collector or other equipment pressure loss.
Site Layout
Rotation, outlet direction, foundation and maintenance space.
Motor Supply
Voltage, frequency and project-specific motor requirements.
If pressure is not known, use the Static Pressure Unknown Guide.
Y6-30 Is for Induced Draft, Not Forced Draft
A boiler induced draft fan extracts flue gas after combustion, while a forced draft fan supplies combustion air before the furnace. The two duties are not interchangeable.
| Fan Type | Position | Function | Selection Focus |
|---|---|---|---|
| Y6-30 Boiler ID Fan | After boiler / dust removal | Extract flue gas and support negative pressure | Temperature, dust, system resistance, chimney route |
| Boiler Forced Draft Fan | Before furnace | Supply combustion air | Combustion airflow and duct resistance |
Drive, Rotation and Outlet Arrangement Must Match the Project
Drive Arrangement
Confirm the drive arrangement from verified technical documentation, required speed, motor arrangement and maintenance conditions.
Rotation Direction
Left-hand or right-hand rotation must match the actual site duct arrangement.
Outlet Direction
Discharge orientation should be confirmed from the project layout rather than assumed.
Motor Configuration
Voltage, frequency, enclosure and destination-market requirements can be reviewed.
When Y6-30 Fits and When Another Boiler Fan Should Be Reviewed
Boiler Flue-Gas Extraction
Boiler induced draft, exhaust after boiler body, negative-pressure support, dust-removal-system exhaust and replacement of an existing ID fan.
Conditions Outside Standard Review
Very high temperature, abrasive ash, heavy dust, corrosive gas, acid-dew-point risk, substantially larger duty or forced-draft service should trigger review of another boiler fan type.
Y6-30 Boiler Induced Draft Fan FAQ
What is Y6-30 used for?
It is used on the boiler exhaust side to extract flue gas and support stable negative pressure.
Is Y6-30 an ID fan or FD fan?
Y6-30 is used for induced draft. Forced draft service should be selected separately.
Why is there no generic Y6-30 performance table here?
The original manual available to us is titled Y6-30-12 and covers No.3.5C through No.8.6C. We therefore keep those verified values on the Y6-30-12 technical page rather than presenting them as universal data for the generic Y6-30 name.
What data is needed for selection?
Send boiler capacity, fuel type, airflow, pressure, flue-gas temperature, dust condition, dust-collector resistance, duct layout, motor supply, rotation and outlet requirement.
When should another boiler fan be reviewed?
Review another boiler fan type for substantially higher duty, very high temperature, abrasive ash, corrosive gas, acid-dew-point risk or forced-draft service.
