Energy savings due to waste heat recovery Since Alfa Laval SHEs recover waste heat from your process, they offer substantially higher energy savings with lower capital expenditure than shell-and-tube heat exchangers. The thermal efficiency of an SHE is two to three times higher than that of a comparable shell-and-tube unit. Valuable energy can
Introduction to Waste Heat Recovery 25 Waste heat in manufacturing is generated from several industrial systems distributed throughout 26 a plant. The largest sources of waste heat for most industries are exhaust and flue gases and 27 heated air from heating systems such as high-temperature gases from burners in process Heat Exchangers IPIECA1. Air to air heat exchanger for waste heat recovery This study reviews how a food processing facility used a heat exchanger to recover waste heat from a process and used it for heating process make-up air. Seeking to control odor from its roasting operation, the facility installed an efficient new Regenerative Thermal Oxidizer (RTO).
RD&D to advance waste heat recovery technologies. Technology needs are identified in two broad areas:1) extending the range of existing technologies to enhance their economic feasibility and recovery efficiency, and 2) exploring new methods for waste heat recovery, especially for unconventional waste heat sources. Acknowledgement Waste heat recovery - Alfa LavalA key component in waste heat recovery is the heat exchanger. The profitability of an investment in waste heat recovery depends heavily on the efficiency of heat exchangers and their associated life cycle costs (purchase, maintenance, etc). Different designs All these factors vary considerably between different heat exchanger technologies.
