Single oxidant situations are not often
present in high temperature industrial
environments. Rather, mixtures of oxygen
with other species are encountered which
make the high temperature corrosion
situation more complex than simply the
formation of a homogeneous oxide scale
on the material surface. Examples of
such environments include various
combustion atmospheres, e.g. oxy fuel
combustion, the combustion of biomass,
industrial residues or domestic waste,
as well as gasification environments
with low oxygen partial pressures and
high activities of e.g. carbon, sulphur
and other constituents. Although
significant efforts have been undertaken
in recent years to throw further light
on such complex conditions, there still
exists a considerable ambiguity and lack
of understanding concerning the
different mechanisms and how their
interactions with one another govern the
long term effects on materials. The need
for further exploration in this area and
for predictable component operation in
such environments has significantly
risen in recent years, as the intention
to more efficiently use available
resources has instigated increased
planning to use hitherto unexploited
fuels and supplies in high temperature
processes. The aim of the workshop,
thus, is to review the current state of
knowledge and understanding in this area
of materials science and to identify the
needs for future research. It will
follow similar approaches of former
workshops in this series of EFC events
on high temperature corrosion. All those
interested in attending and/or
presenting at this workshop are
cordially invited to do so.
