GY5-51 Boiler Centrifugal Forced Draft and Induced Draft Fan
GY5-51 Boiler Centrifugal Forced Draft and Induced Draft Fan is designed for steam boiler forced draft and induced draft systems in thermal power plants. It is suitable for 2t/h to 670t/h boilers and can also meet the high-pressure performance requirements of fluidized bed boiler ventilation systems.
Product Introduction
The GY5-51 series is mainly used in forced draft and induced draft systems of steam boilers in thermal power plants. It is suitable for boiler systems from 2t/h to 670t/h and can also be used where fluidized bed boilers require higher pressure head performance.
In this series, the forced draft fan conveys air, while the induced draft fan conveys flue gas or gas containing impurity particles. When the impurity concentration is below 200 mg/m³, the fan can support more stable long-term service. The working temperature should not exceed 250°C.
Main Features
The series covers both boiler forced draft and induced draft applications, helping match different air supply and flue gas exhaust requirements in boiler systems.
Suitable for 2t/h to 670t/h steam boiler systems in thermal power plants, industrial boiler rooms and related heat supply projects.
The fan series can meet high-pressure head requirements for fluidized bed boiler ventilation and combustion-support systems.
The fan adopts D type transmission with a cantilever structure. The motor and fan are connected through an elastic coupling for stable operation.
Each fan can be configured for left-hand or right-hand rotation. Outlet angle can be selected according to project duct layout and installation direction.
Besides boiler systems, the series can also be used for dust removal, mine ventilation and general ventilation when working conditions are suitable.
Reference Technical Parameters
The following data is for preliminary model selection. Final selection should be confirmed according to boiler capacity, airflow, total pressure, flue gas condition, impurity concentration, working temperature, outlet angle and site installation layout.
Representative Model Parameters
The following representative data is for preliminary model comparison. G5-51 is mainly used as boiler forced draft fan, while Y5-51 is mainly used as boiler induced draft fan. Final selection should be confirmed according to the actual operating point.
Model Meaning and Selection Notes
In the GY5-51 series, "G" generally represents the boiler forced draft fan, while "Y" represents the boiler induced draft fan. The fan outlet position is expressed by the outlet angle of the casing, and the fan can be supplied with left-hand or right-hand rotation according to site layout.
Because boiler fan selection is closely related to boiler capacity, combustion system, flue gas temperature, dust concentration and duct resistance, the final model should be confirmed according to actual operating conditions rather than only by fan name.
Application Scenarios
The GY5-51 series is mainly used in boiler forced draft and induced draft systems. It can also be used in dust removal systems, mine ventilation and general ventilation projects when airflow, pressure, medium condition and working temperature are suitable.
Information Required for Fan Selection
To recommend a suitable GY5-51 boiler fan model, please provide the following working conditions. These details help match fan performance with boiler operation and site installation requirements.
