FIELD: power engineering.SUBSTANCE: frequency of pulsations and phase shift is measured between readings of sensors that record an integral radiant flux, which characterises slagging of surfaces in selected points, and treatment facilities are switched on or off with account of the latter. According to the invention, frequency of pulsations is measured as higher or equal to time constant of blown and non-blown sensors, at the frequency corresponding to the maximum amplitude of its oscillations, and also phase shift of oscillations data recorded by blown and non-blown sensors, and then, using this data and the value of temperature conductivity, they calculate thickness of ash deposits according to the specified ratio.EFFECT: even reduction of thermal resistance of ash deposits formed on a heating surface and prevention of its wear by treatment facilities.1 dwg |
