Abstract
CCS (carbon capture and storage) and oxyfuel combustion
aim for decreasing CO2 emissions in energy production
using fossil fuels. The conditions in power plant boilers
using oxygen firing will change from conventional firing.
This means that higher material temperatures, more harsh
and variable environmental conditions, and new
degradation processes that are not yet fully identified
will be encountered. The aim of this study was to develop
and manufacture FeCrAl alloy by P/M methods and evaluate
the developed material in oxyfuel conditions.
Thermodynamic calculations were used for material
selection. The Fe-Ni-Cr-Al powder was manufactured by gas
atomization. The powder was used for thermal spraying of
coatings by HVOF (high velocity oxy-fuel) and for hot
isostatic pressing of bulk specimens. The high
temperature corrosion properties of manufactured FeNiCrAl
coating and bulk material were tested in laboratory
conditions simulating oxycombustion. The characterization
of the materials before and after the testing was
performed with optical microscopy, and scanning electron
microscopy together with EDX. The manufacturing methods
and the results of high temperature corrosion performance
are presented.
