Abstract

Selection, design, and optimization of the energy
system with the efficient method is one the major problem in recent years. The
combined Emergy-Exergy-Economic-Environmental analysis is one of these new
methods selected for the analysis and optimization of energy systems. In this
paper, the low temperature small solar-driven Kalina power plant is selected
for distributed power generation in Qom city. The analysis procedure based on
Emergy, Exergy, Economic and Environmental concepts is performed in two general
steps. In the first step, the thermodynamic and exergy analysis is performed
and the required thermodynamic and exergetic parameters are determined. For the
calculation of emergy for different component and mass flow, in the second
step, the weight and price of all equipment are evaluated and the emergy
analysis is performed. Based on this analysis the emergy evaluation parameters
such as monetary an ecological performance are presented and based on these
parameters, the most destructive equipment is selected and a suitable procedure
for improvement in the considered system is presented. In the final step, the
exergy and emergy parameters in the proposed solar Kalina cycle are compared
with some renewable and fossil power plant and this comparison show that the
proposed cycle has suitable characteristics.
