Inlet manifold tests and performance evaluation of dephlegmators in air-cooled steam condensers
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: Measurements on air-cooled reflux steam condensers or dephlegmators at different
power plants have shown that sections of these units do not transfer heat effectively
over a range of operating conditions. ...
Performance characteristics of an air-cooled steam condenser incorporating a hybrid (dry/wet) dephlegmator
(Stellenbosch : Stellenbosch University, 2008-12)
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 ...
Steam flow distribution in air-cooled condenser for power plant application
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: Air-cooled steam condensers are used in arid regions where adequate cooling water is not available or very expensive. In this thesis the effect of steam-side and air-side effects on the condenser performance, ...
Numerical investigation of fan performance in a forced draft air-cooled steam condenser
(Stellenbosch : Stellenbosch University, 2005-12)
ENGLISH ABSTRACT: Forced draft air-cooled steam condensers (ACSCs) consisting of multiple fan units are used
in direct cooled power plants to condense steam in a closed steam cycle. Axial flow fans
located below an A-frame ...
Performance trends of an air-cooled steam condenser under windy conditions
(Stellenbosch : University of Stellenbosch, 2007-03)
Air-cooled steam condensers (ACSC’s) are increasingly employed to reject heat in modern power plants. Unfortunately these cooling systems become less effective under windy conditions and when ambient temperatures are high. ...
Air-cooled condenser steam flow distribution and related dephlegmator design considerations
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The steam-side side operation of a practical air-cooled steam condenser is
investigated using a combination of CFD, numerical, analytical and experimental
methods. Particular attention is directed towards ...
Steam flow distribution in air-cooled condensers
(Stellenbosch : Stellenbosch University, 1996-03)
ENGLISH ABSTRACT:
In this thesis the parameters affecting the steam flow distribution through an air-cooled
steam condenser, as found in power generating plants is investigated. The investigated
condenser configuration ...
Pressure drop during reflux condensation of steam in an inclined elliptical tube
(Stellenbosch : Stellenbosch University, 1998-09)
ENGLISH ABSTRACT:
Zapke and Kroger developed a model for the pressure drop across flattened tubes
employed in reflux condensers. This model is based on adiabatic two-phase
countercurrent experiments and incorporates the ...
