Abstract

This
paper summarizes performance analysis of large-scale seawater-cooled box type condenser
in a 660 MW steam power plant. Effect of seawater temperature and steam mass
flow rate are investigated on the key performance parameters of steam condenser.
Results indicated that improvement in the cooling water temperature generally
is found favorable on the performance indicators of condenser. On the other
hand, in the case of steam flow rate changing, effectiveness and overall heat
transfer coefficient almost remain constant. Effectiveness of condenser isn’t
found as a function of steam flow variation. Moreover, steam power plant heat
rate is investigated as a function of cooling water of condenser and thus it is
seen to be decreased in the result of improvement of cooling water temperature.
Conversely, power plant overall thermal efficiency decreases due to reduction
of power generation.
