The causes of corrosion in a boiler

The causes of corrosion in a boiler

There are two common causes of corrosion in a boiler, and right now, we’d like to share them with you, so you will be able to know more about how the Caldera Pirotubular can get them.

1. The corrosion is caused by boiler water

Corrosion will occur in the part where the water is steadily steamed over the combustion chamber above the combustion chamber and show the water pipe to the combustion chamber when some corrosion occurs immediately overcome by chemical reactions when the reaction is rapidly then corrosion occurs not until rooted. If, however, a washing by the chemical reaction will slow the occurrence of corrosion.

2. Corrosion caused by other substances

a. Gas reaction in boiler water

Rusted or corroded iron from submergence in water or high temperatures and use of easily corrosive substances. In this case, the oxygen contained in the water supply is great for perforation or perforation, it is the inner part of the vapor where there is a lack of water change, the running water from the boiler drums and pipes, water pipes and economizer. Carbon acids are the result of carbon dioxide when dissolving in water and react with iron to produce iron carbon. Carbon iron reacts with oxygen to produce the second iron oxide. Since the process of this reaction takes place where carbon dioxide is liberated, thereby speeding up another cycle of the exhaust.

b. Corrosion by nature

One part of the perforation or perforation, the extension of the corrosion area is caused by the separation of the acids in the boiler water and the separation of large/fatty acids from the animal or plant woven in boiler water.

c. Corrosion by salt

The magnesium chloride corrosion in the boiler occurs until it is rooted. This phenomenon is due to the separation of hydrochloric acid results in boiler water and this does not stop in perforation but stops in the form of rust-scale fish extensions, which often occur in parts showing for strong heat where air bubbles are difficult to remove.

d. Corrosion by excessive steam.

Steam is a separator in hydrogen and oxygen when the temperature of the steel surface rises to 400 degrees centigrade or higher. Oxygen is the corrosion of the steel cross-section.
