Influence of geometric and environmental parameters on air-cooled steam condenser performance
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: Air-cooled steam condensers (ACSCs) are used in the power generation industry to directly
condense turbine exhaust steam in areas where cooling water is expensive or unavailable.
Large axial flow fans ...
A numerical investigation of air-cooled steam condenser performance under windy conditions
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: This study is aimed at the development of an efficient and reliable method of evaluating the
performance of an air-cooled steam condenser (ACSC) under windy conditions, using
computational fluid dynamics ...
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, ...
Solar Tower Power Plant Performance Characteristics
(Stellenbosch : University of Stellenbosch, 2004-04)
ENGLISH ABSTRACT: This study investigates energy generation by large-scale solar tower power
plants. The performance characteristics of a so-called reference plant with a
4000 m diameter glass collector roof and a 1500 ...
Perimeter fan performance in forced draught air-cooled steam condensers
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Axial flow fan arrays form part of air-cooled steam condensers in direct drycooled
power plants. This dissertation investigates the performance of axial flow
fans when located at the perimeter of a fan ...
Optimization and control of a large-scale solar chimney power plant
(Stellenbosch : University of Stellenbosch, 2007-03)
ENGLISH ABSTRACT: The dissertation builds on previous research (Pretorius, 2004) and investigates the optimization and control of a large-scale solar chimney power plant. Performance results are based on a reference location ...
The effect of ionization of spray on the wetting characteristics of an adiabatically cooled heat exchanger
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: An investigation was made into the use of pre-cooling of air with evaporative cooling
as a means of improving the performance of air-cooled heat exchangers (finned tube)
under conditions of ambient ...
Characteristics of gas-liquid counterflow in inclined ducts with particular reference to reflux condensers
(Stellenbosch : Stellenbosch University, 1997-12)
ENGLISH ABSTRACT: An experimental investigation on gas-liquid counterflow in inclined rectangular ducts is
conducted. The pressure drop across the sharp-edged gas inlet and the pressure gradient
inside the duct are ...
Die invloed van versteurde inlaatvloeipatrone op aksiaalwaaiers
(Stellenbosch : Stellenbosch University, 1990-12)
ENGLISH ABSTRACT: The causes of disturbances in the flow patterns at the
inlets of axial flow fans that are used in mechanical draft
cooling towers and the effects of these disturbances on the
fans, were investigated.
A ...
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 ...
