FIELD: power industry.
SUBSTANCE: cleaning method of boiler heating surfaces from ash and slag deposits with subsequent periodic impact of cooling liquid jets on deposits is characterised by the fact that there pre-measured on boiler heating surfaces free from ash and slag deposits are distances from support to basic points located on opposite sides of the boiler; then, during the boiler operation there performed is repeated measurement to the same basic points, and on the basis of difference of distances for each basic point there determined is thickness of deposit layer and necessary degree of impact of cooling liquid jets for each basic point.
EFFECT: such method will allow controlling the contamination degree of boiler heating surfaces from ash and slag deposits and effectively cleaning them by having decreased the thermal stress of metal of boiler wall surface, and decreasing its cooling.
