FLUID HEATER Russian patent published in 2006 - IPC F24H1/20 

FIELD: systems for heating liquids fed through pipelines (in home or in different branches of industry), exploitation of pipeline transporting systems.

SUBSTANCE: heater includes housing in cavity of which electrodes are arranged with gap along the same axis in such a way that outer electrode embraces inner electrode; inlet and outlet chambers arranged respectively in end portions of housing. Electrodes are made of chemically inert electrically conducting material, possibly on base of carbon. Housing, inlet and outlet chambers are made of dielectric material. Outer electrode is mounted without gap on inner surface of housing. Size of cross section of inner surface of outer electrode gradually changes along its length. Size of cross section of surface of inner electrode turned to outer electrode gradually changes along its length. Inner electrode is mounted with possibility of reciprocation motion in cavity of outer electrode. Inlet chamber is provided with means for transforming translation motion of liquid to rotation. Outlet chamber is provide with means for transforming rotation of liquid to translation motion. Cyclone is used as means for transforming translation motion of liquid to rotation; housing of said cyclone is used as housing of inlet chamber. Tangential branch pipe of cyclone is communicated with return pipeline of heating system and its axial opening is communicated with receiving opening of heater housing. In order to transform rotation motion of liquid to its translation motion, cyclone is used. Housing of said cyclone serves as housing of outlet chamber, its tangential branch pipe is communicated with inlet pipeline of heating system and its axial opening is communicated with outlet opening of heater housing, and walls of scrolls are formed as Archimedean or Pascal's helix. Conicity of outer electrode is less than that of inner electrode. Inner electrode is arranged as lining of cone tip secured to one end of rod whose other end is provided with thread and arranged in opening with similar thread whose axis coincides with lengthwise axis of electrodes. Said opening is formed in end wall of outlet chamber. Lengthwise axis of electrodes is arranged vertically. In end wall of inlet chamber there is opening closed by detachable pan.

EFFECT: increased resource of heater, reduced dependence of heater operational efficiency from quality of water preparation.
