DeVeTec’s ORC process is based on a conventional closed steam circuit. This process, known as Organic Rankine Cycle, was named after the Scottish physician and engineer William Rankine (1820-1872), who is considered one of the founders of thermodynamics.
The particularity of the procedure used by DeVeTec lies in the fact that DeVeTec uses an organic fluid such as alcohols, (silicone) oils,or refrigerant fluids possessing more efficient thermodynamic properties than water. Consequently it is possible to choose the optimal fluid for each application. The cyclic process always follows the same basic principle. The waste heat from the process or a related heat source is used for the evaporation of an organic fluid in a cyclic process with a moderate pressure. The fluid is then expanded down to a lower pressure in an expander, fed to a condenser and subsequently compressed to the higher pressure before evaporating.
For this purpose, DeVeTec has developed an ORC steam expansion piston engine with a very large pressure difference which can be run profitably within a range from 50 to 270 kWel. Waste heat from your production processes is more precious than ever. Refine it by using the new ORC technology by DeVeTec. You shall gain up to 100% more energy than with comparable systems.
