Regenerator is a heat exchanger where the heat is stored for a while. The heat from the hot fluid is stored in a thermal storage medium before transferring to the cold fluid. Hot and cold fluid pass through a single flow path.
Recuperator is also a heat exchanger used in power engineering to enhance the efficiency of the thermodynamics cycles. Unlike a regenerator, it has a separate flow path for each fluid. The transfer of heat takes place through the separating walls. Recuperator extracts the heat from the waste heat and transfers this to the compressed air. In this way, the air is preheated before entering the combustion chamber. As the air is heated, offsetting some of the fuel, the efficiency of the system improves.
