LIQUID HEATING DEVICE Russian patent published in 2007 - IPC F24J3/00 

FIELD: heat power engineering.

SUBSTANCE: invention can be used as thermal energy source in heating and hot water supply systems. Proposed liquid heating device contains stator with space, inlet channel to let in liquid, outlet channel to let out liquid and rotor with blind holes installed with clearance into stator space. Stator space and rotor are made in form of truncated cone. Radial slots are made on surface of vertex of rotor generating cone and outlet hole is made on surface of stator in center opposite to rotor surface Outlet branch pipe is arranged coaxially with said hole. Perforated sleeve and brake device are stationarily installed inside outlet branch pipe. Bottom with outlet channel is arranged on end face of outlet branch pipe opposite to outlet hole. Cylindrical surfaces of rotor and stator steps have displacement of different direction relative to each other.

EFFECT: increased heating efficiency.
