“…Air-cooled condensers require substantially higher capital investment than wet-cooled condensers because they incorporate larger heat exchangers, have huge fin areas, and necessitate additional support structures (Putman et al, 2002). Overall, installation and operational costs for ACC systems are currently 3.5 -5 times as much as for wet cooling systems (2008).…”

Power plants using air-cooled condensers suffer a 5 -10% plant-level efficiency penalty compared to plants with once-through cooling systems or wet cooling towers. In this study, a model of a representative air-cooled condenser (ACC) system is developed to explore the potential to mitigate this penalty through techniques that reduce the air-side thermal resistance, and by raising the air mass flow rate. The ACC unit model is coupled to a representative baseload steam-cycle power plant model. It is found that water-cooled power-plant efficiency levels can be approached by using enhanced ACCs with a combination of significantly increased air flow rates (+68%), reduced air-side thermal resistances (−66%), and air-side pressure losses near conventional levels (+24%). Emerging heat-transfer enhancement technologies are evaluated for the potential to meet these performance objectives. The impact of ambient conditions on ACC operation is also examined, and two hybrid wet/dry cooling system technologies are explored to improve performance at high ambient temperatures. Results from this investigation provide guidance for the adoption and enhancement of air-cooled condensers in power plants.

“…minimal water only for cleaning of the condenser tube bundles. This cleaning is carried out at fixed intervals to prevent external fouling on the tubes and ensure efficient operation [129]. As discussed, the main drawback of dry-cooling is the reduced CSP power plant efficiency and higher capital costs, and resulting higher cost of electricity.…”

The need to strategically manage CSP fleet development and water resources: A structured review and way forward

The rapid global growth in the use of renewable energy to reduce GHG emissions and mitigate climate change, through the inclusion of large amounts of PV and wind in existing electricity grids, has highlighted certain challenges. Most critically, their intermittent supply, necessitates flexible dispatchability from other generators in the grid. Currently, few renewable energy technologies offer this dispatchability, with only concentrating solar power (CSP) offering storage. CSP generates electricity from thermal heat, similar to fossil-driven thermal power plants, with the heat-source being inexhaustible concentrated solar irradiance. The thermal process, however, requires cooling, best achieved with a finite resource; water. CSP is ideally suited to areas of high solar irradiation, typically arid and water stressed. The need for water as a source of cooling is often neglected in the planning and development of CSP. This paper identifies water as a constraint to CSP deployment, and explores CSP's potential contribution to generation through the lens of the water-energy nexus. This aids our understanding of how water availability threatens expected CSP production capacity and places natural limits on its sustainable development. For strategic planning of CSP, we therefore propose the inclusion of integrated water resource management in CSP energy infrastructure planning.

“…Therefore, an analysis of the condenser plant with the aim of identifying problems and determining the causes of irregular operation is very important. For precise diagnostics, it is necessary to conduct detailed tests of the steam turbine plant and also perform calculations on the behavior of condenser and other systems at the design and at off-design conditions [11][12][13].…”

Analysis of operation of the condenser in a 120 MW thermal power plant

The condenser plant has a huge impact on the economy of a steam turbine power plant. Deterioration of the parameters during operation could lead to a significant decrease in electrical output and to an increase in the heat rate of the thermal power plant. Detailed calculations of the performance under different operating conditions were carried out for the condenser of the Morava thermal power plant. Comprehensive testing of the condenser was carried out and experimental data were compared with the numerical results. The effects of deviations in the condenser behavior on the main thermodynamic parameters and the overall economics of the power plant were evaluated. Guidelines for operation of condensation plants are given in the conclusion.
