• Horizontal or vertical exhaust gas path.
• Natural or assisted circulation.
• One, two or three pressure levels with or without reheating.
• Advanced steam parameters.
• Top supported heat exchange bundles.
• Pressure parts in loose harps or modular sections.
• Drum-type or once-through type HRSGs.
• Cold or hot casing design.
• Supplementary firing or fresh air firing system.
• Design for base load or cycling operation and fast start-up.
• Internal or external deaerator.
