FIELD: power engineering.
SUBSTANCE: invention relates to nuclear and thermal power engineering and is intended for decontamination and prevention of deposition of radioactive deposits on surfaces of equipment, deposits of hardness salts and corrosion products on heat-transfer surfaces of pipelines and equipment, as well as for biological fouling of recirculating and process water supply systems. Device comprises a fundamental frequency generator 1, a modulating frequency generator 2 connected through modulator 3 to the input of the electromagnetic oscillation amplifier 4, which output is connected to inductance coil 5, magnetic conductor 6 enveloping along perimeter pipeline 7 with water solution. Modulating frequency generator 2 operates in frequency range 1–500 Hz, and the main frequency generator 1 operates in range of 30–1,000 kHz.
EFFECT: higher efficiency of cleaning inner surface of pipes and heat exchange equipment.
