DrumPlusTM + diverter damper: a faster way to switch from simple to combined cycle
The combination of NEM Energy’s DrumPlusTM HRSG design and a diverter damper has shown the ability to switch-over from simple cycle to combined cycle at 100% gas turbine load for an F-class gas turbine, without the need for GT ramp down. This enables CCGT plant operators to respond more quickly to grid demands, as well as saving money and reducing emissions. By G. Hariharan, P. Witte, P. Rop, S. Ruijgrok, NEM Energy, The Netherlands
