The targets are to reduce the capital cost and to increase the efficiency of the natural gas fired, dual-pressure CCGTPP configuration shown below:
 |
GT: 260 MWe, 38% efficiency, exhaust gas mass flow 615 kg/sec at 600C.
The design variables are:
- HP steam pressure
- LP steam pressure
- Superheated HP steam temperature
- Feedwater temperature at the inlet to the HP evaporator
- Feedwater temperature at the outlet from the first HP economizer
- Ffeedwater temperature at the inlet to the LP evaporator
- Ssuperheated LP steam temperature
- Ssteam pressure fed to the water tank
- Exhaust gas mass flow ratio (percentage of mass flowrate traversing the LP economizer)
- Exhaust gas temperature at the HRSG outlet
- Steam extraction pressure from the LP steam turbine
- Exhaust gas temperature at the inlet to the condensate preheater
