Zusammenfassung:applicable for chemical cleanings of any heat power equipment of thermal power stations and nuclear power plants, all steam-and-water circuits of boilers, steam generators, turbines, condensers, regenerative heaters, condensate-feeding circuit, as well as hot-water boilers, heat supply systems, boilers, systems of individual heat supply of industrial and dwelling buildings inclusive. SUBSTANCE: the method consists in determination of the qualitative and quantitative composition of deposits, time of complete cleaning tn for the selected detergent composition, its delivery to the circuits, curing and removal of it with dissolved deposits and subsequent water washing with neutralization. The detergent composition is cured for time t(0.4-0.6)tn, and after neutralization water emulsion of the surface-active agent is fed to the circuits, providing for its curing, monitoring thereby the concentration of the surface-active agent; at its reduction to a steady state value water emulsion of the surface-active agent is removed. EFFECT: complete cleaning of surfaces at a reduced time for cleaning. 2 cl
