Scaling of steam generators is very dangerous during use, so it is important to clean the scale regularly during daily use.
After the steam generator manufacturer research shows that the steam generator heating surface with 1 mm of scale, can make the energy consumption increased by about 1.52%. Due to the heating surface with scale, will make the metal pipe wall localized overheating, when the wall temperature exceeds its allowable working limit temperature, it will make the tube bulging, serious will cause pipe burst accident, so that personal safety is threatened. Scale is a kind of complex salts, which contains halogen ions, and has a corrosive effect on iron at high temperature. Through the analysis of iron scale, it can be known that it contains about 2030% iron. Scale erosion of metal will make the inner wall of the steam generator become brittle, and constantly corrode to the depth. Because of the removal of scale to stop the furnace, consume manpower, material resources, as well as cause mechanical damage and chemical corrosion.
Daily scale cleaning method is mainly divided into two kinds, one is the conventional scale chemical descaling method, according to the material of the equipment, the selection of safe and strong descaling cleaning agent, generally control the solution concentration of 520%, but also according to the thickness of the scale to determine. After cleaning, first release the waste liquid, then rinse with water, then fill up the water, and add about 3% of the water capacity of the neutralizer, soak and boil for 0.51 hours, release the residual liquid, and then rinse with water once or twice can be.
Another is the mechanical descaling method, when there is scale or slag in the furnace, after stopping the furnace to release the hearthstone, so that the steam generator cooled, using water flushing or with a spiral wire brush to remove. If the scale is very hard, available high-pressure water jet cleaning power or water-driven pipe cleaner to clean. This method is only applicable to cleaning steel pipe, not applicable to cleaning copper pipe, because the pipe cleaner is easy to damage the copper pipe.
 
Here as a steam generator manufacturers to remind the majority of users must do a good job of scale maintenance.
