Combined heat power system

A combined heat power system comprising:

• a Rankine cycle, said Rankine cycle using a fluid both in gaseous phase and liquid phase, said Rankine cycle comprising
• an evaporator configured to evaporate the fluid from liquid phase to gaseous phase;
• an expander configured to expand the fluid in gaseous phase provided by the evaporator, the expander being suitable to transform energy from the expansion of the fluid in gaseous phase into mechanical energy;
• a condenser configured to condense the fluid from gaseous phase from the expander to liquid phase;
• and
• a fluid pump configured to pump the fluid in liquid phase provided by the condenser to the evaporator;
• a heat source that provides exhaust gas, said exhaust gas providing thermal energy to evaporate the fluid from liquid phase to gaseous phase by said evaporator, and
• a generator unit configured to convert mechanical energy from the expander to electrical energy to inject power into a grid or a battery, the expander being a volumetric expander,
• wherein said expander, said generator unit and said fluid pump are coaxially mounted so that the fluid pump is mounted below the expander, and
• wherein said expander, said generator unit and said fluid pump are coaxially mounted inside a second heat exchanging unit.
