Abstract: The Republic of Kazakhstan in terms of geography is in a wind zone of the northern hemisphere, and large parts of Kazakhstan there are enough strong air currents, especially the north-east, south-west directions. In some areas of Kazakhstan annual average wind speed is greater than 6 m/s, making these areas attractive for wind power development. In times of greatest need for heat and power generation of wind turbines can be damaged due to wet snow drifts, followed by a sharp decrease in air temperature and the formation of heavy ice on them. One possible way to protect the outer surface of the operating wind turbines from sticking of wet snow is heated by warm air flowing through the internal channels of the device. Thermal protection is a more radical way. This paper discusses the method of calculating the flow of heat through the wall of the air of the real device. Using this methodology, complete consumption were determined amount of heat to the walls of a specific channel.
