Low-Temperature ORC Systems: Power From Heat Others Discard
Low Temperature ORC
Most industrial waste heat is not scorching; it is warm, the heat of cooling water, gentle exhaust and process condensate that is too cool for a steam turbine to touch. Low-temperature ORC systems are engineered precisely for that band, generating electricity from heat as low as roughly 80 °C that every other cycle rejects.
How a Low-Temperature Cycle Works
A low-temperature ORC uses a working fluid chosen to boil within the available temperature difference. Even heat that only reaches 80 °C to 150 °C can vaporise the right fluid, and that vapour still expands through a turbine to produce power. The cycle is smaller in output than a high-temperature system, but it operates on an energy source that is otherwise worth exactly nothing.
Why the Low End Matters
The low-temperature range is where most real waste heat actually sits, in cooling loops, jacket water and process condensate across industry. Because that heat is abundant but individually weak, the economics turn on the ORC being correctly sized and matched to the stream, after which the recovered power is essentially free energy that improves a plant’s balance without any new fuel.
