METHOD OF THERMAL PROTECTION FOR OPERATING CAROUSEL-TYPE WIND-DRIVEN POWER PLANT AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2012 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: method of thermal protection for operating plant with Darie turbine that consists of vertical stationary rack and coaxial rotation shaft connected to operating turbine blades by flywheel or by troposkino technique; the method lies in heating provided for all elements by warm air by means of inner natural ventilation of the plant, at that flow-through system is provided through the whole plant with used air discharge into atmosphere. Method is implemented in the plat where upper edge of rotation shaft, which represents flowing passage, is connected to hollow flywheels in the form of NASA - 0021 vane profile at which ends NASA - 0021 T- or L-shaped hollow blades are fixed forming flow-through system communicating with warm air source in the lower part, at that there are holes for air discharge at blade tips. Method is also implemented in another plant with bow-shaped hollow blades NASA - 0021 fixed to rotation shaft by their low ends and to shaft end by their top end, at that rotation shaft is equipped with adjacent ring channels; one channel is connected to top end of hollow blade, the other is connected to low end of hollow blade and used air discharge is made in medium part of the blade.

EFFECT: invention allows stable operation of the plant in severe climatic conditions by means of anti-icing and freezing protection.
