　　Boiler firemen must be certified and have professional firefighting capabilities. When to start the furnace, when to increase the pressure, when to blow off the sewage, when to make up water, when to stop, etc., the relevant operating standards must be strictly implemented to ensure the safe use of the furnace. Industrial boiler feed water quality requirements are extremely strict. Why can't industrial boiler feed water use tap water? What are the functions of boiler water softening equipment

1. The reason why industrial boilers cannot use tap water

　　Impurities in tap water are divided into suspended impurities, colloidal impurities, and soluble impurities, which can cause certain harm to the boiler.

　　1. Affect the effect of boiler water treatment

　　If the boiler feed water is treated with chemical water in the pot, suspended impurities can directly reduce the scale inhibition effect of the added scale inhibitor, and waste the chemical. If the boiler feed water is treated with chemical water outside the boiler, the switch in the exchanger will be polluted by suspended impurities, resulting in reduced water output and unqualified water quality;

　　2. Affect the safe operation of the boiler

　　The suspended matter entering the boiler will deposit on the bottom of the lower header of the drum and become mud scale, which affects heat transfer and even causes unsafe accidents such as boiler overheating and tube burst;

　　The harm of colloidal impurities:

　　1. If a resin exchanger is used for chemical water treatment outside the pot, colloidal impurities will enter the pores inside the resin exchange particles, block the water flow channel, lose or reduce the exchange capacity, and cause poisoning of the resin exchanger;

　　2. If colloidal impurities enter the boiler directly, it will form extremely hard scale on the boiler, which is difficult to remove and is extremely harmful to the safe and economic operation of the boiler;

　　3. The colloidal impurities directly enter the boiler, which will also cause the boiler water to foam, pollute the steam, and affect the normal operation of the boiler;

　　The harm of soluble impurities:

　　1. Calcium and magnesium ions are scale-inhibiting ions, the most important component that causes boiler scaling, and the two most harmful ions to the safe and economic operation of boilers;

　　2. The presence of chlorine ions in the water quality can accelerate the corrosion rate of the boiler. This corrosion is usually localized, and it is also very harmful to the boiler;

　　3. A small amount of iron ions in the water quality can poison the strong acid cation exchanger and bring a lot of maintenance to the boiler water treatment work;

2. The role of boiler softening water equipment

　　Water softening equipment is to treat boiler feed water, remove calcium and magnesium ions in the water, reduce boiler hardness, avoid boiler fouling, and reduce the production of the above harmful substances. Generally, the hardness of boiler feedwater is 0.03mmol/L, which ensures the quality of boiler feedwater and the effect of boiler operation.

The above briefly introduced why can't tap water be used for industrial boiler feed water? For issues such as the role of boiler softening water equipment, it is everyone's responsibility to appeal to the majority of boiler users, scientifically, rationally use the furnace, and create a safe furnace environment.
