Thermoeconomic optimization of the steam power plant

... [8,9]. In the thermoeconomic analysis of a system, the calculation is started from the point where power fluid enters the system. Because the output of an element is the input for another. In the cost ... first and second law analysis of thermodynamics is applied to the examined steam power plant. According to the results of the first law analysis, the v...
