Abstract
This study evaluates the performance characteristics
of a power plant incorporating a steam turbine and a
direct air-cooled dry/wet condenser operating at
different ambient temperatures. The proposed
cooling system uses existing A-frame air-cooled
condenser (ACC) technology and through the
introduction of a hybrid (dry/wet) dephlegmator
achieves measurable enhancement in cooling
performance when ambient temperatures are high.
During these periods the hybrid (dry/wet) condenser
operating in a wet mode can achieve the same
increased turbine performance as an oversized aircooled
condenser or an air-cooled condenser with
adiabatic cooling (spray cooling) of the inlet air at a
considerably lower cost. For the same turbine power
output the water consumed by an air-cooled
condenser incorporating a hybrid (dry/wet)
dephlegmator is at least 20 % less than an air-cooled
condenser with adiabatic cooling of the inlet air.
