RANKINE POWER GENERATION CYCLE
3. Heat transfer in the ideal Rankine Cycle relies on phase change, a very efficient way to store and release energy. The working fluid is usually water/steam. During the cycle, the properties of the working fluid change as below with associated heat/work exchanges. h (kJ/kg) P (kPa) T (oC) s (kJ/kg-k) q or w (kJ/kg) 1Æ2 Small increase h1 = hf ...

This gives a double benefit: Recovered heat reduces purchased heat (and cost) and also reduces the ancillary power necessary to reject the heat. There are also non-economic reasons for utilizing heat recovery.
