FIELD: heat engineering.
SUBSTANCE: invention relates to heat engineering, namely to the technique of chemical descaling of heating surfaces. The effect is obtained by chemical descaling method implying the introduction of the forced circulation of a chemical cleaning solution in the heat exchanging loop; the solution contains hydrochloric acid solution and corrosion inhibitor as well as chrysotile with the following ratio of components, wt %: hydrochloric acid (4-5), corrosion inhibitor (1-2), chrysotile (0.05-0.1), water (remaining part).
EFFECT: invention allows for the creation of a protective film on the cleaned surface which prevents the repeated scale formation.
