, discarded) heat in industrial processes are reviewed, and an overview of off- the-shelf technology available for its use is given. Discussions of waste heat measurement technology and economics are included, as are 14 case studies of successful. As the industrial sector continues efforts to improve its energy efficiency, recovering waste heat losses generate cost savings, reduces environmental impact, and improves work flow and productivity. By recovering waste heat, plants can reduce energy costs and CO2 emissions, while simultaneously increasing energy efficiency. Examples of waste heat recovery systems are: Economizers: Boiler. Thermal oxidizers can use a regenerative process for waste heat from industrial systems. The sources of this heat could originate from hot exhaust gases, cooling towers, or even just hot surfaces. Definition: What is waste.
