Monitoring and analysing methods for corrosion studies

Corrosion of superheater tubes in power plant boilers was performed with air-cooled probe, where material temperatures can be adjusted and monitored. Specimens of different materials can be attached to the probe and their corrosion behaviour and deposit formation can be analysed. Analysis is done to carefully prepared metallurgical cross-sections by SEM/EDX. Deposits can be analysed separately.

This method is applicable especially to material screening and material testing for difficult and changing boiler conditions, such as biofuel fired boilers and waste incinerators.
