Abstract

An energy crisis has become a global problem which restricts
the sustainable growth recently. For this reason, waste heat recovery from
different thermal systems has become so important. There are many ways to utilize the waste heat, and absorption cooling systems are one of the best
ways to use waste energy. On the other hand, Power plants are at the forefront
of industries where energy consumption is most intense. For this reason,
improving the performance of these plants will save energy, water, as well as
contribute to the prevention of environmental risks. In this study, a new and a
suitable absorption cooling system was
proposed for recovering the waste heat from drainage tanks in AL-Zara steam
plant in Hama in Syria. In addition, thermal and economic analyses were applied
to study the feasibility assessment of using waste heat based on the measured
data from Al-Zara steam power plant. The absorption cooling cycle of the drainage tank water works by NH₃-NaScN
as a working solution, which achieves the highest coefficient of performance (COP) at available
thermal conditions where reaches to (0.49). The profitability in order to three
cooling units reaches to (37206 €), compared
with the compression cooling cycle that is similar it in the capacity
