Exergy cost accounting and thermoeconomic diagnosis for Double-Solar-Gas-Turbine system (DSGT)

Investigation of Kalina Cycle for Power Generation from Heat Dissipation of Tarasht Power Plant

“…In the restricted dead state (*), in which only the temperature and pressure are changed to the environmental values [35]. The exergy destruction in each component can be evaluated based on fuel and product exergy [36] The amount of net power was obtained from the modeling of the power plant for one unit of 10.047 kW and all four units 40.188 kW and from the modeling of the Kalina cycle 2080 kW, which shows that the production power of the power plant has increased by 5.18%. If the temperature of the exhaust gas is less than 257℃; the amount of net production power and heat transfer will decrease, the results are shown in Table 8.…”
