Dear PowerPlant Chemistry readers:
Earlier this year, in March, the International Conference on Film Forming Substances took place in Heidelberg,
Germany. FFS 2019 was a unique conference on a narrow topic in the cycle chemistry control of
power plants but attracted over 70 participants from 22 countries. The highlights and press release can
be found here. This journal aims to inform our readers about recent conferences,
and for those who haven't been able to attend the conferences due to insufficient traveling resources, it
is our goal to have interesting presentations published in our journal. This is not always an easy task â€“ due
to lack of time, conference presentations are often available only as presentations and do not appear as
a paper in conference proceedings. Therefore, every presentation which finds its way into our journal is a
special one insofar as the authors have taken their time and resources to present to you, our readers, their
latest research and developments in their cycle chemistry field. We will try our best to publish some of the
presentations from FFS 2019 in one of the upcoming issues.
Of course we are always interested in papers which haven't been presented at a conference yet. I am
already looking forward to your letters and e-mails announcing a future contribution to our journal.
In this issue, we present the last in a series of five articles which have appeared in this journal on corrosion
and deposits in water-cooled generator windings. The main goal of this series has been to give a detailed
update on the mechanisms, prevention, diagnosis, and removal of flow restrictions in water-cooled generator
Another topic in this issue is wet-limestone flue gas desulfurization. The author examines the fundamentals
of this process and discusses modern developments to maximize scrubbing efficiency in these systems.
And last but not least you can find the latest Technical Guidance Document (TGD) issued by the International
Association for the Properties of Water and Steam here. This TGD considers
the phenomenon of air in-leakage (AIL) in fossil, combined cycle/HRSG, and biomass plants. It covers the
importance of AIL in the performance and cycle chemistry control of generating plants. The sources of AIL
are delineated as well as the background science.
