The Cheng Cycle®
The Cheng Cycle®
The Cheng Cycle® is a patented technology for converting new and existing gas turbine plants to highly efficient & clean power generators that are especially beneficial for the peaking and intermediate load electrical power markets. There is less de-rating of the Cheng Cycle® at high temperatures and altitudes, and the Cheng Cycle® offers higher part-load efficiency.
The Cheng Cycle® has a small plant footprint area, produces very low emissions without additional active environmental controls, has fast startup and shutdown times and has demonstrated high reliability and long service life.
Cheng Cycle is a patented steam injection emission control technology designed to increase power output, but it will also potentially improve efficiency and reduce NOx

PowerMagJune2003.pdfCheng Cycle® is a patented technology for converting new and existing simple-cycle gas turbines to highly efficient and clean power generators that are especially beneficial for the peaking and intermediate load electrical power markets.
The Cheng Cycle® incorporates full heat recovery massive steam injection and uses an energy-storage heat-recovery steam generator (HRSG) design with automatic control of thermodynamic feedback for stable operation at maximum efficiency.
The Cheng Cycle® is recognized worldwide as a heat recovery steam injected gas turbine cycle and has 35 years of operating history.
Cheng Cycle® has been applied to Kawasaki M100-13 2.5 MW, RR Allison 501 6 – 8 MW, GE Frame 6B 42 MW, GE LM 2500 27.5 MW systems. Completed engineering for the retrofit of GE 7EA, 7FA, LM6000 PC, Westinghouse W501 D5A and 501F systems.
The Cheng Cycle® offers efficiencies equaling and capacities exceeding those of the combined-cycle plant for the underlying simple-cycle engine type without the steam turbine, steam turbine generator and associated cooling loop, control systems and auxiliaries of the combined-cycle plant.
