High pressure boilers usually have high quality feeding water. The use of cation-free and anion-free water has made the boilers prone to corrosion. It should be noted that high-quality water also contains, small amount of sedimentary substances that precipitate on the boiler walls as a result of water evaporates. The disadvantages of such scales are sub-scale corrosion as well as lack of sufficient heat transfer and more energy consumption. The best way to protect high pressure boilers is to use Mitreh 1167 solution. By injecting this solution into the feed water of these boilers, in addition to removing scales from the boiler wall, it also prevents corrosion in the system because it is neutral. Another advantages of the Mitreh 1167 is the ability to deposit the boiler during operation.
Calibration of Using Mitreh 1167 Solution:
In order to remove scales formed in high pressure boilers the volume of solution consumption varies, depending on the amount of scales present in the system, and to obtain the best performance you need to consult the technical experts of the company.
System water analysis and scale formed at the installation, estimation of approximate amount of scale available at the installation, the volume of make-up water during the day, and the kind of alloys in the various parts of the system are required prior the scale removing operation. Better advice shall be obtained from relevant experts at the Abrizan Company.
In the case of severe corrosion in the system and thinning of the body of the installation, carry out the deposition more carefully and consult the relevant experts.
