HYDRODYNAMIC WATER HEATING METHOD, AND WATER HEATING PLANT Russian patent published in 2013 - IPC F24J3/00 

FIELD: heating.

SUBSTANCE: heat generator is installed in a closed circuit, at which vortex flow of water is formed due to conversion of a head created with a pump and the received flow is accelerated in a water movement accelerator, with further removal of heat obtained in the heat generator from outlet water flow to the consumer. At that, at the heat generator inlet, water flow is broken with an air cavity in the zone of its phase transition, in which the impact of drops of water at its outlet in atomisation cones is provided. An air cavity is formed at the inlet of the heat generator housing, and a volute has the shape of logarithmic spiral; at that, flow of liquid from the volute to a vortex pipe is performed through the logarithmic spiral pole, and a centrifugal pump and a shutoff valve is installed between a suction pipeline and a delivery pipeline.

EFFECT: obtaining more energy-saving method and economic water heating plant.
