Abstract

The design, construction and experimental investigation of the thermal performance of waste heat recovery in a gas-to-air heat pipe recovery system is carried out. The system under study transports waste heat from exhaust gas to an air-cooled condenser. The system consists of two rows of five inverted U-shaped gravity assisted heat pipes charged with distilled water as working fluid. Experimental results were compared with a theoretical model based on the Effectiveness-Number of Transfer Units(ε-NTU) method and were in good agreement. Recovered energy achieved 64W with a 50oC temperature difference between the inlet and outlet air in the condenser air-cooled heat exchanger. This system also has the advantage of easy assembly and disassembly.
