A theoretical and experimental investigation into the thermodynamic performance of a 50 MW power plant with a novel modular air-cooled condenser

Experimental Investigation on Seismic Behavior of Steel Truss-RC Column Hybrid Structure with Steel Diagonal Braces

“…To reflect the energy dissipating degree of the specimen with the increase of PGA, the relative dissipated energy ratio is defined as the ratio between the cumulated hysteresis dissipated energy of the specimen under different loading cases of the PDTs calculated by Equation (9), equivalently the corresponding PGA is 0.05, 0.10, 0.20, 0.30, 0.40, 0.60, and 0.80 g, and the cumulated hysteresis dissipated energy of the specimen under the final loading case of PDTs (PGA = 0.8 g). Figure 13 shows the cumulated hysteresis dissipated energy (E h ) and the relative dissipated energy ratio of the specimen under different loading cases.…”

“…Despite more or less symmetric floor planning in both horizontal directions, the stiffness and mass are usually unevenly distributed in the vertical direction due to the peculiar characteristics of structural components and industrial requirements. Past studies mainly focused on the ACC technology including experimental investigation, numerical simulation and optimization [4][5][6][7][8][9]. However, the supporting structure of the ACC system was addressed rarely.…”

Review on Wind Effect and Axial Fan Performance of Air Cooled Condenser for a Thermal Power Plant

“…The installation of A frame ACCs has increased exponentially in the last 15 years. This has occurred despite the fact that they have been shown to suffer from significant design flaws such as susceptibility to wind effects, air-flow maldistribution, and non-uniform temperature profiles, all of which contribute to reduce ACC effectiveness [7]. Moreworryingly still, however, is the limited ability of current ACC designs to respond to variations in ambient temperature.…”

“…Ultimately, this leads to a loss of operating income. Therefore, in light of these issues with current ACCs, there is significant scope and motivation for improvement in their design if they are to become the pre-eminent cooling strategy for future powerplants [7]. Long banks of ACHEs are, however subject to flow maldistribution at the fan inlets that adversely affects the operation of the axial flow fans which ultimately reduces the cooling capacity of the installation.…”

Effect of inclination on pressure drop and flow regimes in large flattened-tube steam condensers

“…The main focuses of the past research about the ACC systems were on the characterization and optimization of air-side heat transfer and pressure drop performances, such as the effect of air-flow maldistribution, wind effects, non-uniform temperature profiles and other drawbacks. A detailed investigation into the performance of a power plant with an air-cooled condenser was discussed by O'Donovan and Grimes [30].…”
