FIELD: power industry.
SUBSTANCE: in contrast to the prototype, in the method consisting in pumping the cleaning solution through pipelines and internal cavities, before cleaning the system is emptied from working fluids, two washing solutions are prepared - alkaline, containing SAA, and acidic, solutions are heated up to 320…360K, are pumped alternately, starting with the alkaline solution, through the pipelines and internal cavities of the equipment. The solutions pumping alternates with the pumping of a neutral liquid, for example, water. The device includes pipelines, taps or valves, containers, pumps and is additionally equipped with two containers for cleaning solutions and a container with a neutral liquid, as well as a generator of pressure pulsation and speed.
EFFECT: improved cleaning quality.
