The combined cycle and variations that use HRSGs

This is a much higher efficiency than can be achieved by either the Brayton or Rankine cycle alone. To combine these two cycles, a means to recover the waste heat from the gas turbine exhaust must be provided. The modern day heat recovery steam generator (HRSG) has met this need and is the bridge between the two cycles.
