FLOWING INDUCTIVE LIQUID HEATER Russian patent published in 2006 - IPC H05B6/10 

FIELD: power engineering, possible use in construction of devices for electric heating of liquids.

SUBSTANCE: device has toroidal winding of inducer, applied to core, consisting of steel tubular coil pipe with applied winding of steel band. Magnetic duct, product duct and heating element of heater are combined, and core realizes their functions. To decrease specific metal consumption down to 2-2,5 kg/kWt during operation of inductive heater strong magnetic fields are used with strength 25-40 kA/m. coil pipe has coils of similar radius, and winding of steel band is tightly pressed to whole external surface of coil pipe, so that all ferromagnetic substance takes part in heat exhaustion, electric resistance of heater is decreased, and, as a result, its metal consumption. To prevent steel corrosion and to heat food liquids, thin-walled insert is used made of stainless steel, positioned in coil pipe tube. To improve heat exhaustion from heater core to liquid flowing along coil pipe, wire spiral is used of stainless steel, which is inserted into coil pipe tube, and is used to provide additional circulation of liquid.

EFFECT: higher efficiency.
