Improving steam turbine efficiency: pick valid method(s) Common cycle/plant modifications to raise efficiency. Choose the best option.

Concept/Approach

• Reheat reduces moisture at turbine exhaust and increases mean temperature of heat addition.
• Regenerative feed heating increases boiler feedwater temperature, boosting cycle efficiency.
• Binary/combined vapour plants (e.g., steam with topping/ bottoming) raise overall efficiency.

Final AnswerAny one of these — each method improves turbine/plant efficiency.
