The FLOWCHEM^® processes stop corrosion and scale formation in steam power plants.

The targets of modern, safe and low energy steam power plants are:

• to avoid scale formation
• to reduce corrosion of metals
• to avoid draining of boiler water

Some examples to demonstrate:

Blistered boiler tube

For many reasons local hot areas may have harmful effects on the boiler tube. In this case the wall tube was overheated long-term by deposits of ferrous oxide causing short but strong local overheatings.

Stress-crack corrosion breaking in an inner tube

This type of corrosion takes place when boiler water steam is concentrated in a crack or under scales.

Attack of acid in a boiler tube.

Extreme surface corrosion is caused by cleaning a boiler with acid or by leaking mineral acid. In such cases the affected part of the equipment should be disused.
