Organic rankine cycle
Figure 3 shows the main components of the ORC system which
are boiler, turbine, generator, condenser and pump. In the conventional
ORC, high temperature heat is absorbed at the boiler (Q ) at
temperature around 80-120°C which in this study is hot spring. After
that the working fluid at the high pressure and temperature enters to the
turbine (state 1) for producing the electricity at the generator (W ).
Next, the working fluid at the low pressure (state 2) is condensed at
the condenser by cooling fluid at temperature around 30-40°C. The
working fluid in liquid phase (state 3) is pumped to the boiler (state 4)
and the new cycle is started again.
