Kurzbeschreibung

In this project the feasibility of the Organic Rankine Cycle Principle for waste heat recovery was investigated with an - in general - positive result. First of all the potential of waste heat in industry usable by ORCS was evaluated and the typical properties of ORCS usable heat sources were defined. In the second step we collected data about the working fluids, the expansion engines and the other components of a Rankine cycle. These data are presented in the final report so that potential users can design an ORCS for their heat sources, can evaluate the investment costs, the pay-back period and the rentability of his plant. A cost sensitivity study is given for seven ORC plants differing in the temperature level, the working fluid, the efficiency and the energy recovering rate. The investment costs, the time of amortization and the rentability are compared. We projected ORC plants for three typical applications in a few power output categories and evaluated the investment costs, the pay-back periods and the rentabilities. The main result is that the less sophisticated plants get a higher benefit than plants with a high energy efficiency. The results of our tests are as follows: Screw expanders are usable up to about 100 kW for R114 with 5 % lubricant. For higher temperatures turbines in connection with toluene get advantages, because the consequent separation between working fluid loop and lubricant loop is possible. For performances higher than 100 kW turbines for R114 and toluene are recommended.
