Combined Cycle GT (CCGT)
GTs have at best efficiencies from 35% to 42%. Almost 60% of the fuel energy is wasted in the turbine exhaust of a GT. Capturing this waste heat in a heat recovery steam generator (HRSG) is the basis of the combined cycle (Brayton + Rankine). The HRSG produces steam that drives a turbo-generator to produce additional power.
