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 ...
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. ...
Thermal performance evaluation of artificial protective coatings applied to steam surface condenser tubes
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The coating thermal conductivity, the effective coated-tube thermal conductivity and the coating factor of three artificial protective coatings (APCs) applied to condenser tubes are experimentally ...
Performance trends of a large air-cooled steam condenser during windy conditions
(Stellenbosch : University of Stellenbosch, 2011-03)

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 ...
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 ...
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 ...
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. ...
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, ...
Simulating the effect of wind on the performance of axial flow fans in air-cooled steam condenser systems
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The use of air-cooled steam condensers (ACSCs) is the preferred cooling method in the chemical and power industry due to stringent environmental and water use regulations. The performance of ACSCs is ...
