4 FAQs about Bottom diameter of wind turbine fan

How efficient is wind energy fan?

The Wind Energy Fan (WEF) has high-efficient utilization of wind energy. The performance of Wind Energy Fan with lift-type wind turbine and Drag-type was studied and compared. WEF-System with Drag-type wind turbine is easier to start up than with lift-type wind turbine. WEF-System with Lift-type wind turbine of 3 blades is relatively optimal.

What is wind energy fan system (WEF-system)?

The Wind Energy Fan system (WEF-System) can realize the efficient ventilation in underground engineering by utilizing wind energy to drive the axial fan with the vertical wind turbine directly. The wind turbine in WEF-System is a key equipment to catch the wind energy, its performance affects the ventilation performance of WEF-system directly.

Which type of wind turbine is best for underground engineering?

WEF-System with Lift-type wind turbine of 3 blades is relatively optimal. The Wind Energy Fan system (WEF-System) can realize the efficient ventilation in underground engineering by utilizing wind energy to drive the axial fan with the vertical wind turbine directly.

Does a lift-type wind turbine increase the speed of a fan?

It is easily found that the less number the blade of Lift-type wind turbine, the larger the rotating speed of the fan increases obviously.
