      Picture two chambers separated by a pipe.

      In the left chamber heat and water are introduced and the water transitions to steam.  In the right-hand chamber heat is rejected, the steam is condensed, and liquid water is extracted.  Because of the huge expansion/contraction involved in the phase changes, the two processes going on simultaneously should result in a high-velocity flow of saturated steam in the connecting pipe.

      If no energy is extracted from the connecting flow, the heat rejected at the sink is equal to the energy supplied to the left chamber minus the usual parasitic cluster of viscous losses, etc.

      If, however, you run the (saturated) flow through a turbine- the shaft work extracted can ONLY come from a phase change in the steam.
       
      The condensation/boiling temperature is a function of the pressure. If you transition to steam then go through a turbine, the condensation pressure will be lower and the condensation temp has to be lower. This makes the heat exchangers larger as well I think.
