A recuperator is a type of heat exchanger used to recover waste heat from exhaust gases in various industrial processes, particularly in areas like power generation, heating systems, and HVAC applications. The primary purpose of a recuperator is to improve energy efficiency by reusing heat that would otherwise be lost, thus reducing the overall energy consumption of a system. In operation, a recuperator typically transfers heat from the hot exhaust gases to a cooler fluid (like air or water) that needs to be heated.
