The problem of bringing with it is heat-exchanger pipeline mediation cleaning difficulty.Though the piece of heat-exchange tube middle junction is loose spot, and loose spot also all is the high temperature dust that does not have bonding with the upper part, because tube wall is longer, the block part of luming is not usually at the mouth of pipe, and in the pipe middle part, the tube wall diameter only is 75 mm.Prior art is to dredge by force with metal bar, and ducted nothing bonding high temperature dust here similarly is " drift sand " that is subjected to vertical gravitation in the fixed volume, is subjected to the frictional force of tube wall, iron staff is more smash downwards, the density of these " drift sands " is just more big, and the resistance of smashing is also more big down, dredges very difficult.
Consequence:1, the mediation time long, mean that to stop kiln (stopping working) time also just more long, influence the longevity of the interior anti-material of Fu Kasi kiln kiln.
Be subjected to radial tension when 2, being dredged, heat-exchange tube tube wall easy deformation, even break, and the back of breaking repairs difficulty influences heat exchanger service life.
3, the human and material resources input is too big, owing to stop the long of kiln time, influences output simultaneously.
