A comprehensive review on the exergy analysis of combined cycle power plants

Genetic Algorithm Approach to Design of Multi-Layer Perceptron for Combined Cycle Power Plant Electrical Power Output Estimation

“…In energy and exergy analyses of CCPPs and its components, several researchers obtained the same conclusions about elements which have the highest losses from both (energy and exergy) aspect. The highest energy losses in CCPP of any kind can be found in steam condenser [9,10], while the highest exergy losses occur in gas turbine combustion chambers [9][10][11]. These conclusions are confirmed by several researchers and for CCPPs of different size, power output and configuration, so it can be concluded that they are valid in general.…”

Thermodynamic Cycle Concepts for High-Efficiency Power Plans. Part A: Public Power Plants 60+

“…This can be reached by increasing the thermal efficiency of the applied cycle and/or by increasing the efficiency of its individual components. In the case of the most recent and most technologically advanced large steam power plants, the efficiencies of their machinery and equipment are very high and we cannot expect that they can be further significantly increased [23][24][25][26][27][28]. For instance, the maximal efficiency of boilers ranges within 92-95%, high-pressure turbines 88-94%, medium-pressure turbines 90-97%, low-pressure turbines 88-95%, electric current generators 98.5-99%, and water pumps-about 85%.…”

Experimental and numerical study of forced convection heat transfer in different internally ribbed tubes configuration using TiO2 nanofluid

“…The mechanism of heat transfer enhancement of internally ribbed tubes depends on the stream reattachment and separation by ribs . The experimental studies demonstrate that ribs with multiple heads provide heat transfer of fluid by a helical stream in various heads ribbed tubes . The enhancement can be imputed to the reduction of the thermal boundary layers thickness on the wall …”
