Problems solved by technology

Boiler corrosion will not only shorten the service life of the equipment, directly affect the safe operation of the boiler, and cause economic losses, but also the corrosion products of the boiler will be brought into the steam turbine or other equipment, which will seriously affect the life and safe operation of these equipment
[0003] In the prior art, phosphate, phosphate, sodium hydroxide, etc. are commonly used as scale inhibitors for boiler water treatment. Although these scale inhibitors can temporarily solve the problem of boiler water scaling to a certain extent, there are many defects, such as phosphorus discharge. problems, vapor carryover of sodium salts, etc.

Description

technical field [0001] The invention relates to the technical field of boiler water chemical treatment, in particular to a compound type high-efficiency boiler water treatment agent. Background technique [0002] Various types of corrosion occur in boilers during operation and decommissioning. In general, boiler corrosion is divided into chemical corrosion and electrochemical corrosion. Among them, electrochemical corrosion is more common and more harmful in boiler corrosion. The feed water of the boiler is an electrolyte. In the case of uneven chemical composition, different organizational structure, uneven deformation and internal stress, and incomplete metal surface film, many corrosion micro-batteries will be formed on the metal surface, resulting in electrochemical corrosion. Oxygen corrosion, acid corrosion, and corrosion under deposits, which are common in production, all belong to electrochemical corrosion. Boiler corrosion will not only shorten the service life o...
