This great degradation of temperature needed to evaporate the steam,results in a poor power plant cycle efficiency,because high cycle efficiencies are only achieved by increasing the evaporation temperature.In contrast to this,organic fluids have a much lower ratio of evaporative heating to feed heating and hence can easily attain much higher temperatures,therefore giving better cycle efficiencies.An example of this is shown in Fig.4,where,using the same heat source,it is possible to evaporate pentane at 180 ◦C.This is generally considered to be a safe upper limit for pentane in order to avoid thermal stability problems associated with chemical decomposition of the fluid.
