A combined heat power system (110) comprises a Rankine cycle, optionally an organic Rankine cycle, using a fluid both in gaseous phase and liquid phase. The Rankine cycle comprises
- an evaporator (4) for evaporating the fluid from liquid phase to gaseous phase,
- an expander (5a) for expanding the fluid in gaseous phase provided by the evaporator (4). The expander (5a) is suitable to transform energy from the expansion of the fluid in gaseous phase into mechanical energy,
- a condenser (6a,6b,6c) for condensing the fluid from gaseous phase from the expander (5a) to liquid phase and
- a liquid pump (5c) for pumping the fluid in liquid phase provided by the condenser (6a,6b,6c) to the evaporator (4).
The system (110) comprises a heat source (3) providing exhaust gas. The exhaust gas provides thermal energy for evaporating the fluid from liquid phase to gaseous phase by the evaporator (4). The system (110) further comprises a generator unit (5b) for converting mechanical energy from expander (5a) to electrical energy. The expander (5a) is a volumetric expander. |
