Warm air heating device for preventing icing-up of rotor blades of wind power plant

摘要

The device has one or more air intake tubes (2) on the flange of a rotor blade into which the air found in the system outside the rotor blade is blown in. The air is heated. There are other air exit holes (4) through which the air emerges again in order to be guided again through the fan and heater to the rotor blade (3). The connecting hoses between the heater and the air intake tubes are flexible, as are those between the air exit holes and the heater. The air hoses have holes. There are holes at the tip (8) of the rotor blade.
