【文摘】：

The emergence of several challenging issues such as climate change, fuel price hike and fuel security have become hot topics around the world.

Therefore, introducing highly efficient devices and heat recovery systems are necessary to overcome these challenges. It is reported that a high portion of industrial energy is wasted as flue gas from heating plants,boilers, etc. This study has focused on the application of nanofluidsasworking fluids in shell and tube heat recovery exchangers in

a biomas sheating plant. Heat exchanger specification, nanofluid properties andmathematical formulations were taken from the literature to analyze thermal and energy performance of the heat recovery system. It was observed that the convective and overall heat transfer coefficient increased with the application of nanofluids compared to ethylene glycol or water based fluids. It addition, 7.8% of the heat transfer enhancement could be achieved with the addition of 1% copper nanoparticles inethyleneglycol based fluid at a mass flow rate of

26.3and116.0kg/sforflue gasandcoolant, respectively.
