The applicability of ORC technology varies with
the parameters of every energy source and needs
to be customized for every installation. The major
parameter that determines the choice of technology,
is the temperature of the heat source, whether it is
waste heat or renewable energy. Figure 3 shows the
applicability of different type of ORC technologies at
different waste heat source temperatures. Typically,
the Steam Rankine Cycles are used if the temperature
of waste heat source is higher than 350°C.
