recuperator
Sign in to savethumb|400px|Types of recuperator, or cross plate heat exchanger A recuperator is a counter-flow energy recovery heat exchanger that recovers waste heat in the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process. Generally, they extract heat from the exhaust and use it to preheat air entering the combustion system, reducing the need for fuel and boosting the system's energy efficiency.

==Description== In many types of processes, combustion is used to generate heat, and the recuperator serves to recuperate, or reclaim this heat, in order to reuse or recycle it. The term recuperator refers as well to liquid-liquid counterflow heat exchangers used for heat recovery in the chemical and refinery industries and in closed processes such as ammonia-water or LiBr-water absorption refrigeration cycle.
