Boiler material corrosion testing with a corrosion probe
In boiler material corrosion testing, a corrosion monitoring probe with a test piece is placed inside the fluidised bed boiler. The probe can be placed in the combustion chamber or in the drop flue at the desired level. The probe is both water- and air-cooled, keeping it at the desired temperature.
Boiler and exchanger material testing in the material test chamber
1. A corrosion monitoring probe is placed in the material test chamber at the desired temperature, and the test pieces on the probe are kept in the desired conditions under flue gas flow. Temperature is adjusted by valves and by mixing flue gases in the chamber.
2. Larger pieces, such as air-flue gas exchangers, can also be tested. The material test chamber features a hatch for placing in exchangers and other large objects. Flue gas is directed across the object to test how it stands up to contamination and corrosion from flue gas at a certain temperature.
