Condensation of a steam-inert gas mixture in an Oxyfuel condenser differs significantly
from condensation of pure steam: condenser pressure and rest gas content increase dramatically,
heat- and mass transfer coefficients are lower and oversaturation of the steam-inert
gas mixture yields to fog formation.
In the context of this thesis, therefore, at first the optimal ranges of working parameters
for Oxyfuel processes calculated. In the following some heat flux measurements were
carried out on a horizontal, crossflow pipe to validate various heat- and mass transfer
theories. Building on these results a new, efficient condensation concept was developed
to reduce fog formation. The final results of the measurements with a laboratory model
show great performance regarding fog reduction and condensation efficience.
