N2 - The paper presents an analysis of relations describing entropy generation
in a condenser of a steam unit. Connections between entropy generation,
condenser ratio, and heat exchanger effectiveness, as well as relations
implied by them are shown. Theoretical considerations allowed to determine
limits of individual parameters which describe the condenser operation.
Various relations for average temperature of the cold fluid were compared.
All the proposed relations were verified against data obtained using a
simulator and actual measurement data from a 200 MW unit condenser. Based
on data from a simulator it was examined how the sum of entropy rates,
steam condenser effectiveness, terminal temperature difference and
condenser ratio vary with the change in the inlet cooling water
temperature, mass flow rate of steam and the cooling water mass flow rate.
