China's first intelligent infrared de-icing equipment successfully completes trial operation

China's first intelligent infrared de-icing equipment for wind turbines successfully completed a trial operation at the Datang Wugong Mountain Wind Farm in east China's Jiangxi Province on Saturday.

This milestone signifies a new technological breakthrough in the field of intelligent ice removal for large-capacity wind turbines in the country.

This equipment simulates the principle of solar radiation, using infrared rays to rapidly warm up the wind turbine blades for quick thawing.

A single unit of equipment can melt three centimeters of ice on the blade surface within 20 seconds and start shedding ice accumulation within one minute in the irradiated area. The energy output is five to eight times that of sunlight in summer.

Furthermore, it also features two intelligent modes, "anti-freezing" and "de-icing". It functions like a real-time "weather forecaster", monitoring the environment to prevent icing in advance.

In cases of severe ice accumulation, it can accurately de-ice the entire wind turbine within one hour, enabling the giant blades equivalent to a 30-story building in height to resume operation.

This technology adopts a non-contact design and has currently been successfully validated on the wind turbine with a capacity of five megawatts (MW).

It is particularly suitable for the complex environments of wind farms in frigid alpine areas.
