Waste heat recovery is the process of capturing and reusing the heat that is generated by industrial processes or combustion, which would otherwise be lost to the environment. This captured heat can then be used to generate electricity, heat buildings, or power industrial processes. Waste heat recovery can be applied to a wide range of industries, including power generation, petrochemical, and manufacturing, and can lead to significant energy savings and reduced greenhouse gas emissions.
Waste heat recovery can be done by using techniques such as thermoelectric generators, Organic Rankine cycle, and Kalina cycle systems, and heat exchangers. These systems can capture waste heat from sources such as flue gases, hot water, or steam and convert it into usable energy.
Overall, waste heat recovery can help to increase the overall energy efficiency of industrial processes, reduce costs, and reduce the environmental impact of these processes.
