Waste heat sources at low-temperature can be recovered
With the use of an adapted Organic Rankine Cycle (ORC), waste heat sources at low-temperature, can be recovered.
An ORC uses a closed circuit with an organic working fluid which can be evaporated and condensed at low temperatures and pressures. The fluid is evaporated and is forced to pass through an expander to generate electricity. These systems are mainly used as heat recovery systems in the industry with medium-temperature ranges (generally in big heat production installations like thermal power plants).
