FIELD: power industry.
SUBSTANCE: there is provided cleaning method of at least one heat-transfer element of waste heat boiler hanged on support structure. The support structure has weighting system for measuring the force applied to the support structure by at least one heat-transfer element. The said method includes the creating of cleaning system that has at least one cleaning element with cleaning possibility, the defining of efficiency rate of at least one cleaning element by way of weighting system use. The defining of efficiency rate includes the measurement of force applied to support structure by at least one heat-transfer element, cleaning of at least one heat-transfer element by at least one cleaning element, further measurement of the force applied to support structure by at least one heat-transfer element and comparison of the force measured before and after the said cleaning of at least one heat-transfer element and cleaning system control based on efficiency rate. Note that cleaning system control includes the defining of operating efficiency of at least one cleaning element based on efficiency rate of at least one heat-transfer element and actuating of at least one cleaning element connected with at least one heat-transfer element, operation control of at least one cleaning element for cleaning of at least one heat-transfer element with the aim to improve sludge removal, movement of cleaning element inside waste heat boiler furnace from first position outside the furnace to the second position near heat-transfer element - first step and movement outside the furnace from the second position to the first position - second step. Note that cleaning element initially operates either in the first step or the second step, but if the removal of enough ash failed, the cleaning element can operate in both steps.
EFFECT: method improvement.
