Waste heat recovery is the process of capturing and utilizing thermal energy that is generated as a byproduct of industrial processes, power generation, or other operations, instead of allowing it to dissipate unused into the environment. This recovered heat can be converted into useful forms of energy, such as electricity, steam, hot water, or heating and cooling, through various technologies and systems.
The primary objective of waste heat recovery is to improve energy efficiency, reduce energy consumption, and minimize environmental impact by harnessing otherwise wasted heat and converting it into valuable energy resources. By capturing and utilizing waste heat, industries and facilities can lower operating costs, increase process efficiency, and enhance sustainability.
Waste heat recovery technologies include heat exchangers, heat pumps, organic Rankine cycle (ORC) systems, thermoelectric generators, and combined heat and power (CHP) systems. These technologies enable the recovery and utilization of waste heat from exhaust gases, process streams, and industrial equipment, contributing to resource conservation, emission reduction, and energy independence.
