ANTI-ICING AND DEICING METHOD AND DEVICE FOR HIGH-POWER WIND TURBINE BLADES

摘要

A modular gas-heat anti-icing method as well as a device for high-power windturbineblades are provided, wherein a modular heating system is provided on the bladeroot, aventilation duct is provided inside the blade, a wind deflector is provided atthe end of theventilation duct, which divides the front edge of the blade into two parts, sothat the hot airin the ventilation duct is only to be conducted to the blade tip and thencirculates into theblade root via the rear edge of the blade, enabling the hot air to circulateinside the bladeand form a "blade root to blade tip to blade root" closed loop, such that thefront edge ofthe blade is heated so as to reduce icing.
