Energy conservation is a key goal of economy and it will
continue to be in near future. The most effective way to meet the
energy demand is to use energy more efficiently. The exergy
analysis [1,2] method is a useful tool for promoting the goal of more
efficient energy-resource use, as it enables the locations, types and
true magnitudes of wastes and losses. The exergy analysis shows
the true measure of loss which is evident from the results of energy
and exergy analysis reported for various types of thermal power
plants of various capacities [3–6]. The popularity of exergy analysis
method has grown consequently and is still growing [7–11]. Habib
and. Zubair [7] quantified irreversible losses in components of
a regenerative Rankine cycle power plant and concluded that
maximum irreversible loss takes place in boiler, and regenerative
feed water heating reduces irreversible loss in boiler and whole
plant. Singh et al. [3] carried out the energy and exergy analysis for
the system components of a typical 50 kW solar–thermal power
plant (STPP) under given operating conditions. The typical 50 kW
STPP uses thermic fluid in solar collector field. The highEnergy conservation is a key goal of economy and it will
