Modeling water use at thermoelectric power plants
The withdrawal and consumption of water at thermoelectric power plants affects regional ecology and supply security of both water and electricity. The existing field data on US power plant water use, however, is of limited granularity and poor quality, hampering efforts to track industry trends and …

A Comparative Study of Cooling System Parameters in U.S. Thermoelectric Power Plants
As the importance of water use in the power generation sector increases across the nation, the ability to obtain and analyze real power plant data is pivotal in understanding the water energy nexus. The Navajo Generating Station in Arizona and the Browns Ferry Nuclear Plant in Alabama are examples …

Technoeconomic Analysis of Textured Surfaces for Improved Condenser Performance in Thermoelectric Power Plants
… electrodeposition process for condenser tubes in thermoelectric power plants. The textured surfaces are expected to provide enhanced performance by deterring fouling and promoting dropwise condensation of the steam on the shell side. Using a thermal resistance network of a shell and tube …

Increasing the Heat Transfer on a Grooved Surface Under Dry and Wet Conditions by Using of Jet Impingement
… One major application is for condensers of thermoelectric power plants. The heat and mass transfer analogy were successfully used to evaluate the simultaneous heat and mass transfer. Results showed that hybrid jet impingement produced high heat flux levels at low jet velocities and flow …

Integrating water resources and power generation: the energy-water nexus in Illinois
Thermoelectric power plants contribute 90 percent of the electricity generated in the United States. Steam condensation in the power generation cycle creates a need for cooling, often accomplished using large amounts of water. Negative consequences of power plant water demands, such as dialing down …

Integrating thermoelectric power generation operations with aquatic ecosystem sustainability
Open-loop thermoelectric power plants, representing 30% of the electricity generation in the United States, withdraw and discharge large quantities of water for cooling purposes. This process can cause thermal pollution in waterways, adversely affecting aquatic ecosystems. Incorporating biology …

Experimental Investigations on Non-Wetting Surfaces
… sustained dropwise condensation in a typical power plant condenser environment. The surfaces are shown to produce heat transfer coefficients up to 7-10 times that of film-wise condensation, with condenser effectiveness of 0.92 or better compared to effectiveness of about 0.6 in conventional …

Simulating the performance of the 24 ft. installed MinWaterCSP axial flow fan
Air-cooled condensers (ACCs) are used in thermoelectric power plants as dry-cooling solutions which reduce a plant’s reliance on water to cool the working fluid. These condenser systems use arrays of large diameter axial flow fans to discharge heat to the ambient air. However, assessing the …

Augmentation of Jet Impingement Heat Transfer on a Grooved Surface Under Wet and Dry Conditions
… at a constant temperature. For the flat surface, power and temperature measurements were performed to obtain convection coefficients under a wide range of operating conditions such as jet speed, orifice to surface stand-of distance, and open area percentage. Cooling performance (CP) was calculated …

WATER-ENERGY-CLIMATE NEXUS: INTERDEPENDANCIES AND TRADEOFFS, AND IMPLICATIONS FOR STRATEGIC RESOURCE PLANNING
… first study deals with the vulnerability of U.S. thermoelectric power plants to climate change. Findings suggest that the impact of climate change is lower than in previous estimates due to the inclusion of a spatially-disaggregated representation of environmental regulations and provisional …

Vulnerability of Coal- and Natural Gas-Fired Power Plants to Climate Change
… warming will reduce the efficiency (η) of thermoelectric plants by 0.12-0.45% for each 1°C of warming. In Chapter 2, we evaluate these predictions using historical performance data for 39 open- and closed-loop, coal and natural gas plants from across the U.S., which operated under daily and …

Energyshed to Watershed: Linking Water and Energy Consumers to Their Environmental Impact and Water Resources
… while energy production, particularly in thermoelectric power plants, relies heavily on water and contributes to greenhouse gas emissions. This interdependency poses challenges in arid regions and population centers, where high water demands strain energy systems and droughts impact power …
