WASTE HEAT RECOVERY - Thermopedia

Waste heat recovery aims to minimize the amount of heat wasted in this way by reusing it in either the same or a different process. Waste heat can be recovered either directly (without using a heat exchanger—e.g., recirculation) or, more commonly, indirectly (via a Heat Exchanger). Direct heat recovery is often the cheaper option but its use is restricted by location and contamination considerations.
