Unless the fuel such as heavy oil is burned more than before, the required heat energy cannot be obtained. Therefore, an increase in fuel cost is unavoidable, and the cost required to operate the boiler and heat exchanger increases. In order to eliminate such a situation, conventionally, the first method, in which the surface of a tube or the like is blown with high-pressure steam or air to blow off the soot or scale adhering to the surface, the scale, etc. Either the second method of washing the surface of the tube or the like to which the tube adheres, or the third method of rubbing the surface of the tube or the like with a wire brush to scrape off the scale or the like.

いものとされてきた。However, according to the second method, when the tube wets with water and is formed of a material that is particularly susceptible to corrosion, rust is likely to occur and the refractory material is damaged, resulting in a short service life. It may get hard. Further, since soot, scale, etc. are firmly and thickly adhered to the surface of the tube, soot, scale, etc. cannot be easily removed by any of the first to third methods. Further, generally, in a boiler or a heat exchanger, a large number of tubes are arranged in a complicated manner in multiple stages, so in these methods, the above-mentioned action force does not work to the back side or the place where it enters, It is impossible to remove the scale and the like at these places. Furthermore,
In the third method, since fine metal projections are directly rubbed against each other, a tube made of a soft material such as aluminum or a tube made thin to increase thermal efficiency is used.
There is a risk of breaking or deforming the bumps. Therefore, it is impossible to completely remove the soot scale and the like that lower the thermal efficiency, and it is unavoidable that the fuel cost increases as the burning time of fuel such as heavy oil elapses. It has been.

スケ−ル等を除去できないものであった。This proposal simply sprays a large amount of walnut, which is an expensive abrasive, with the air to collide with the surface of the tube at a high speed, so that it is arranged in multiple stages in a complicated arrangement. It is impossible to completely remove all the soot scales and the like attached to each of the many tubes that have been cleaned in a single cleaning operation, and the cleaning costs are high, but the cleaning costs are high. Soot scale, etc. cannot be removed. Also, because high-hardness walnuts collide at high speed,
A thin tube, a tube made of an aluminum material, or the like may be broken or deformed. In view of such circumstances, the above-mentioned proposals can remove the soot scale and the like adhering to the tube or the like to such an extent that the thermal efficiency is remarkably improved only under extremely limited conditions.

When it reaches 1, it passes through the introduction side spiral fin facing space SP1 having a wide space volume. Thereafter, the slurry-like polishing and cleaning material is split from the introduction-side spiral fin facing space SP1 through the same process as described above in the directions of arrows 33 and 35 shown in FIG. At this time, the spiral fin 29 is made of a thin aluminum plate, iron plate, copper plate or the like due to its structure, and is spirally provided in the cylindrical portion 37 at a fine fin pitch FP interval.

As a result of such a flow operation, as shown in FIG. 16, the slurry-like abrasive cleaning material is subsequently subjected to the spiral fin diagonal facing space S as described above.
Since the P2 and the flow-side spiral fin facing space SP3 flow alternately, the slurry-like polishing and cleaning material is used in the nozzle 28.
The initial injection speed of the injection from the pipe is gradually decreased, and the Amemi spiral fin tube group 3 is arranged in multiple stages.

場に落流する。When the above-mentioned slurry-like cleaning material collides or makes frictional contact, the initial velocity of jetting is slowed down while maintaining the crystal body having the cutting edge line which makes a sharp frictional contact action. At the same time, the water content of the slurry-like abrasive cleaning material plays a role of cushion during collision. For this reason, the impact force at the time when the fine particles of baking soda or cereal flour / husk powder in the unit of micron continuously collide with each of the cylindrical portion 37 and the spiral fin portion 29 and the initial impact force of frictional contact are significantly attenuated. The aluminum spiral fin tube 31 group is not broken or deformed. Then, the scale S attached to the aluminum spiral fin tube group 31 is caused by the continuous action of the frictional contact force of the crystal body under the action of the significantly damped collision force.
Etc. are continuously scraped off little by little, and the attached scale S etc. are removed. After the scale S is removed, the baking soda completely dissolves in the water and flows down to the cleaning work site, while the fine particles of the flour and husk powder do not dissolve in the water and maintain the fine particle state. Then, it is dropped into the cleaning work site along with water.
