FIELD: heating system.
SUBSTANCE: in the proposed method and device for producing steam and thermal energy, a hydrodynamic (hydromechanical) action is applied to the liquid as a result of the formation in the device of high-speed rotating hydrodynamic flow in which conditions are created for numerous local discontinuities of liquid flow and the appearance of microcavities in it with intensive processes of high-speed mechanical cavitation occurring in them. Wherein, vacuum "bubbles" are generated in the liquid, which instantly collapse. When the spherical vacuum cavity of bubbles collapses, the pressure in them sharply increases, as in the explosion, causing numerous internal explosions in the liquid directed inside the cavitation bubbles with the formation of shock waves, which leads to the emission of compression pulses, forming microzones with large pressure drops. The liquid repeatedly, with a large frequency, changes its aggregate state - instantly evaporates, and then instantly condenses and, as a result, it intensively heats up. That is, the heating of liquid takes place completely according to a different principle: there is no source of external heat, and there is no heat transfer surface, since heat is formed directly inside the liquid and remains there. Wherein, the liquid, being under a certain excess pressure caused by the centrifugal force arising during rotation, significantly "overheats" and under certain conditions becomes vapour.
EFFECT: heating process takes place "inside the liquid" with minimal heat loss.
