Testing and Modeling a Vane Expander Used in an ORC Working with Hexamethyldisiloxane (MM)

Original language description

Waste heat from industrial production carries considerable potential for further use. Organic Rankine Cycle (ORC) brings a possibility to produce electrical energy from heat, originally intended to be released to the surroundings. For ORC systems with power output up to 10 kW, small - scale turbines are still expensive to manufacture and their use can be problematic in terms of high shaft speed or quality of inlet vapor. It is therefore preferable to use positive displacement expanders. The first part of this paper presents and analyses the measurements conducted on a prototype of vane expander. This vane expander characterized by a 1 kW power output operates in an ORC heat engine that uses hexamethyldisiloxane as a working fluid. The expander inlet temperature varies approximately from 135 °C to 150 °C, inlet pressure varies approximately from 200 to 300 kPa abs, isentropic efficiency from 0.4 to 0.58. The second part of the paper proposes a grey - box model, which is calibrated on th
