Our unique ORC vapour expansion engine
The centrepiece of a DeVeTec waste heat power plant is the piston-driven vapour expansion engine (piston expander), which was developed by DeVeTec ourselves, and is manufactured in house.
Piston-driven expansion engines achieve an exceptionally high pressure difference, resulting in a much steeper enthalpy gradient and consequently much more electricity is generated compared to related technologies. Another considerable advantage of the piston-driven expansion engines lies in its impressive partial load capability.
Depending on the amount of waste heat available, the V8 engine works within a range between 0 and 130 kW, theV12 engine between 0 and 200 kW, or the V16 engine between 0 and 270 kW with almost constant efficiency. If other lower temperature heat sources are to be exploited, then the same engine can be operated with other organic fluids without requiring any modifications.
