FRICTION HEATER Russian patent published in 2013 - IPC F03D9/00 

FIELD: power industry.

SUBSTANCE: friction heater includes a heated medium tank, in which there installed are fixed friction elements and turning friction elements connected to a drive shaft and installed with a gap between them, side walls and the bottom of the tank. Upper turning friction element is made in the form of a disc, and lower turning friction element is made in the form of a ring. Fixed friction elements are made in the form of shoes installed with possibility of their interaction with the turning friction disc and the ring. Mixing blades are installed between the disc and the ring. The tank is provided with holes in lower and side parts. Lower turning friction element can be made in the form of a ring with the width equal to width of lower friction shoe. Distance between the turning friction disc and the ring is more than their total thickness. Friction shoes can be pressed to the disc and the ring by means of stiff springs.

EFFECT: invention ensures simple design and enlargement of functional capabilities at reduction of cost.
