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

FIELD: heat engineering.

SUBSTANCE: device for heating liquid comprises stator provided with the spaces composed of cylindrical space and conical space arranged symmetrically around the cylindrical space. The diameter of the base of the cone is less than that of the cylinder. The inlet passage is made of swirling device and is mounted coaxially with the central opening of the stator that is ended with the round member or chamfering. The outlet passage for discharging liquid is made in the cylindrical surface of the stator. The rotor is mounted with a spaced relation to the stator for permitting rotation. The rotor is made of a disk secured to the shaft. The face surfaces of the cylindrical part of the stator and disk are provided with at least one row of dummy openings. The similar openings are made in the cylindrical surface of the disk.

EFFECT: enhanced efficiency.
