Abstract
Nowadays coal-based power plants have still a 25% share in energy
production in
Hungary. Consequently, professional treatment of the yearly accumulating
large volumes
of ash/flying ash is an important task from environmental, as well as
national economic
aspects. Since power plants have gradually switched during the recent years
to hybrid-fluid technology, substantial part of sulphur accumulates in
fine ash/flying ash. It is
important to know in which form the sulphur component becomes absorbed in
the flying
ash-water pulp of approximately 1:1 mixing ratio. This study presents the
thematic as well
as temporal evolution of the detailed determination of mineralogical
composition
