Abstract
The integration of concentrated solar and conventional
power plants is one of the most promising and recently
growing renewable technologies for electricity and heat
generation in large scale. The hybrid concepts enable
reduction in the consumption of fossil fuels and
greenhouse gas emissions as the solar field produces part
of the plant's heat/steam load. The objective of this
work was to study how the thermal stresses in a
superheater tube fluctuate during a day in a combined
CSP-CFB power plant with dynamical modelling in Apros.
Secondary aim was to find the dynamical events taking
place in the studied process concept.
The thermal stresses in a superheater tube were found to
fluctuate during a day in a combined CSP-CFB power plant.
The variation in stress was found to be the greatest when
the CSP plant was connected to the CFB steam circuit in
the morning. However, the changes in stress can be
decreased by better control methods. These can be
developed using the Apros CSP-CFB model. The platform
provides excellent base to study dynamical behaviour of
the integrated energy production and to develop and
optimize control strategies, upper level controls, and
operational practices. Material issues can also be
studied with the new material stress module.
