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 Gas Turbine
The file (4.26 MB) will cover the following topics:
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.
Topics – Combined Cycle GT
- Operating Principle of a Combined Cycle GT
- Combined Brayton + Rankine Cycles
- Comparison of Various CCGT Configurations
- CCGT (Gas vs Liquid Firing)
- CCGT Energy Balance
- Examples of Gas Turbine Technologies
- Cost of GT Technologies
- GT and CCGT Plants in the Philippines
- Advantages, Disadvantages of CCGT
- Environmental Impact, Risks of CCGT
