SUBSTANCE: invention relates to wind power engineering and may be used to produce wind energy and convert it into electrical, mechanical, thermal energy or their different combinations. Air flow is captured from wind and accelerated in a narrowing channel, and is supplied into a device with a water jet by a pump, where water and air flow is produced. The water-air flow is accelerated to supersonic speed, and is then turned into subsonic water-air flow of the fuel. Energy is extracted from the specified subsonic flow in the turbine, and then the flow arrives into the receiving reservoir, where water and air are separated. The residual pneumatic energy of the separated compressed air is additionally converted into electrical or mechanical energy. The residual thermal energy of compressed air and water is used accordingly for air and water heating or hot water supply.
EFFECT: usage of the invention makes it possible to exclude a blade wind turbine, to reduce weight and dimensions of a device, to increase reliability and to ensure uninterrupted power supply to loads with various types of energies.

SUBSTANCE: invention relates to the field of heat power engineering and may be used to provide hot water supply and heating of buildings and structures located in areas with no centralised heat and power supply. A thermal wind turbine comprises a rotor wind engine with a vertical shaft, which transmits rotary motion via a reducer to a round plate, to which vertical cylindrical partitions are fixed at the bottom, being submerged into a heat insulated tank with water. Cylindrical partitions are also fixed to the bottom of the tank, and partitions fixed on the round plate move between those. Water arriving into the tank, flowing via movable (rotary) and fixed partitions is heated due to friction. Since the gap between movable and fixed partitions is chosen as minimum possible for water passage, water heating is carried out quite effectively, which is also supported by a roll arranged in the form of a net increasing friction made on the surfaces of cylindrical partitions. Blades mounted on the outer side of the external (relative to the central axis) movable (rotary) cylindrical partition help to pump water into the outlet nozzle of the tank and back to the load.
EFFECT: higher efficiency.
