Laboratory-Simulated Fuel-Ash Corrosion of Super Heater tubes in Coal-Fired Ultra-Supercritical Boilers
The corrosion behaviour of Ni-base alloys of different composition together with a highly-alloyed austenitic stainless steel has been investigated with and without various coating of the samples with alkali-containing synthetic coal ash. The effects of various parameters have been studied, namely the Cr content the test temperature, the SO2 content in the gas and the alkali sulphate content of the ash. The results can be explained on the basis of the differences in corrosion mechanisms resulting primarily from the composition of the alloys tested.
