System Components
The major components of an ORC system are the
following:-
yy Heat exchangers (preheater, evaporator, cooling
and condensing units)
yy A regenerator (used mostly in waste heat recovery
systems)
yy An expander (mostly positive displacement
systems such as scroll and screw expanders
rather than turbo machines)
yy A turbine
yy A generator
yy Ancillary systems include pumps, instrumentation
and control systems, online control panel and an
electricity feeder (to be connected to the electrical
transmission system).

yy System monitoring is done mostly through online
software systems, and can be started/shut down
easily through the online systems.
