Abstract EN
The failures of superheater and reheater boiler tubes operating in a power plant utilizing natural gas or mazut as a fuel have been analysed and the fire-side corrosion has been suggested as the main reason for the failure in boiler tubes.
The tubes have been provided by a fossil fuel power plant in Iran and optical and electron microscopy investigations have been performed on the tubes as well as the corrosion products on their surfaces.
The results showed that the thickness of the failed tubes is not uniform which suggests that fire-side corrosion has happened on the tubes.
Fire-side corrosion is caused by the reaction of combustion products with oxide layers on the tube surface resulting in metal loss and consequently tubes fracture.
However, the tubes corrosion behaviour did not follow the conventional models of the fire-side corrosion.
Given that, using the corrosion monitoring techniques for these boiler tubes seems essential.
As a result, the thickness of the boiler tubes in different parts of the boiler has been recorded and critical points are selected accordingly.
Such critical points are selected for installation of corrosion monitoring probes.
