How to prevent boiler scaling? Answer: To prevent scale formation in the boiler and ensure its safe and economical operation, the following measures should be taken: ① Improve the treatment of water supplied to the boiler to ensure that its quality meets **standards. ②Carry out timely dosing and blowdown of the boiler to ensure that the quality of the boiler water meets **standards. ③Strengthen the operation management of boilers to prevent corrosion in their steam and water systems, and reduce the iron content in the feedwater, so as to ensure that the boilers operate without scale or deposits.

(1) The main cause of boiler scaling is hard water; prolonged use leads to the accumulation of large amounts of ions such as calcium, sodium, and magnesium, which then deposit on the surface of the boiler metal. The methods for removal start with water quality treatment, and then proceed to furnace cleaning. It is best to leave the specific work to professionals. (2) Scaling in boilers is mainly caused by water quality issues. Tap water is considered hard water, as it contains high levels of soluble calcium and magnesium compounds. When heated, these soluble calcium and magnesium compounds transform into insoluble substances, leading to the formation of deposits. The more impurities present in the water, the higher its hardness; and the greater the hardness, the easier it is for scale to form. Excessive buildup of scale can affect thermal efficiency, increase heat loss, and raise energy consumption. The main method for removing scale is chemical treatment; 2.5 kilograms each of sodium hydroxide and trisodium phosphate are added per ton of water to treat the boiler. Of course, according to the requirements of thermal and steam regulations, it is best to use softened water. The energy cost associated with scale formation is much higher than that of using softened water; therefore, it is necessary to install a system for softening water in boilers. Currently, chemicals are used to remove scale.
