2. Performance Figures

3. Steam Turbine

4. Arrangement Planning


Motivation to develop a new standardized CCPP:

• New available gas turbine H-80 with radial exhaust (Hot-End-Drive) within the Hitachi Power Segment

• Lack of available Combined Cycle Power Plants in th e 150 MW-class with 1 GT resp. 300 MW -class with 2 GT

Requirements to the new CCPP-Concepts:

• Compact and less consuming area demand plant design

• Optimized for decentralized combined production of distri ctheat and-/or process steam extraction and electricity

• Optimal economic efficiency for both power- and heatoriented operation �� plant concept without reheat!
