(54) СПОСОБ ОЧИСТКИ ПОВЕРХНОСТЕЙ НАГРЕВА(54) METHOD FOR CLEANING HEATING SURFACES
II
. .
Изобретение относитс к котепьно- 3 почвой технике и может быть испо1аао вано дл очистки поверхностей нагрева . котпоагрегатов от наружных отпожёний в энергетике,. металлургии и других област х техники.The invention relates to the boiler-3 soil technique and can be used to clean the heating surfaces. kotpoagregaty from external otgozheny in power ,. metallurgy and other areas of technology.
Известен способ очистки поверхностей нагрева путем изменени давлени внутри поверхности нагрева, что в определенном импульсном режиме создает вибрацию труб 1..A known method of cleaning heating surfaces by changing the pressure inside the heating surface, which in a certain pulsed mode creates the vibration of pipes 1 ..
Недостатком такого способа вл етс низка эффективность очистки ара. наличии прочно св занных с материалом труб отлож ений..The disadvantage of this method is the low cleaning efficiency of macaws. the presence of pipe deposits closely associated with the material.
Цель изобретени - повышение э.ффек- тивности очистки поверхностей нагрева.The purpose of the invention is to increase the efficiency of cleaning the heating surfaces.
Поставленна цель достигаетс тем, что согласно способу очистки поверхностей нагрева, закгаочающемус в им у ьоном изменении параметра внутренней ереды , в качестве параметра внутренней среды принимают температуру, которуюThe goal is achieved by the fact that, according to the method of cleaning heating surfaces, which change the parameter of the internal stage in them, the temperature is taken as the parameter of the internal medium
1Й§ мен ют на 4О-12О°С от исходной величины путем прсмененн охладител .Z1 is changed to 4 ° -12 ° C from the initial value by means of a replaced cooler.
Способ осуществл етс следующим образом .The method is carried out as follows.
При изменении температуры поверхности с имеющимис на ней отложени ми в металле труб возникают термические напр жени , которые привод т к изменению геометрического размера трубы, по законам температурного расщиренн (сжа10 ти ). При этом происходит нарушение сил сцеплени между металлом труб и внутренним слоем отложений, поскольку линейное (объемное) расширение (сжатие ) металла трубы при изменении тем15 пературы превышает линейное (объемное) расширение (сжатие) материала отложений как по величине линейного относительного расширени (сжати ), так и по скорости его изменени от температуры.When the surface temperature changes with the deposits in the metal of the pipe, thermal stresses occur, which lead to a change in the geometric size of the pipe, according to the laws of thermal expansion (compression). In this case, the adhesion forces between the pipe metal and the inner layer of sediments are disturbed, since the linear (volumetric) expansion (contraction) of the pipe metal with a change in temperature exceeds the linear (volumetric) expansion (contraction) of the sediment material as the linear relative expansion (contraction), and the rate of its change from temperature.
