We use the steam generators for a long time will scale, even if there is no too thick scale, it will greatly reduce the thermal efficiency of the boiler, not only waste fuel, but also affect the service life of the steam generator, and even occur safety accidents. So we need to clean the scale on the steam generator regularly.

After we have used the steam generator for some time, it is necessary to check whether the steam generators have produced scale. It is recommended to install a water softener in front of the boiler. It can effectively reduce the hardness of the water, thus extending the service life of the boiler.

We can alkali wash or acid wash the boiler regularly. Alkaline washing is the use of caustic soda and other alkaline drugs to clean the furnace. Its function is to loosen scale and promote it to fall off. Acid wash is the use of hydrochloric acid and corrosion inhibitors to clean the liner, and then combined with alkali boiling. But hydrochloric acid is corrosive to metal, so be sure to pay attention to the amount of hydrochloric acid.
