Indications for damage to boilers in natural water and boiler water treatment
 Basic knowledge of boiler water
There are many impurities in natural water, and the main factors affecting the boiler are suspended matter, colloidal matter and dissolved matter.
 
Suspended matter and cavity materials are composed of mud sand, animal and plant remains and some low molecular aggregates, which are the primary factors that make water turbid. If these impurities enter the ion exchanger, it will contaminate the AC resin and affect the quality of the water. If it enters the boiler directly, it will easily deteriorate the quality of the steam, and it will easily accumulate into mud and block the pipe, causing the metal to be damaged due to overheating. Suspended and colloidal materials can be removed by pretreatment.
 
Dissolved matter primarily refers to salts and certain gases dissolved in water. Natural water, even in seemingly pure tap water, contains various dissolved salts, among which calcium and magnesium salts. That is, the hardness material is the primary source of boiler fouling. Because scale damages the boiler extremely, removing the hardness and avoiding scaling is the primary task of boiler water treatment, and can be reached by chemical treatment outside the pot or dosing in the pot.
 
The main factors affecting the fuel gas boiler equipment in dissolved gas are oxygen and carbon dioxide, which will cause oxygen corrosion and acid corrosion to the boiler. Together with oxygen and hydrogen ions, it is still a highly effective depolarizer, which will accelerate the electrochemical. Corrosion is one of the important factors in the corrosion of boilers. Dissolved oxygen can be removed by means of a deaerator or by participating in a restorative medicine. With regard to carbon dioxide, it is only necessary to adhere to the pH and alkalinity of the pot water to eliminate its effects.
