How to calculate overall thermal efficiency of combined cycle power plants – a sample CCGT presented

Calculating or predicting the overall performance of a combined cycle power plant, specifically a combined cycle gas turbine (CCGT) power plant is sometimes difficult for most design engineers. Your favorite energy technology expert again comes to the rescue – Engineer Marcial T. Ocampo – has derived the following equation to guide the design engineer and project finance modeler or business development engineer in predicting the overall thermal efficiency of the combined cycle.

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.
