Field Validation of a Hot-Air De-icing Retrofit
Wind turbine blade icing affects 65% of wind farms worldwide. Icing results in a reduction of power production, safety hazards for site workers and the public, and the potential for increased wear and tear on turbine components. Borealis Wind has created an after-market system which can remove and prevent ice accumulation on turbine blades. Borealis has designed an internal heating system which can be installed up-tower without the use of rope-access technicians or cranes within one week and without interrupting the night-time production of the turbine. The Borealis ice protection system circulates hot air inside the blade, targeting critical locations like the leading edge and end third.
