The optimization of feed water heaters (FWHs) is a critical strategy for enhancing the thermal performance of power plants operating on the Rankine cycle. By preheating feed water using turbine extraction steam, FWHs reduce boiler heat input requirements, improve cycle efficiency, and lower greenhouse gas emissions. However, inefficiencies due to suboptimal operating conditions, heat transfer limitations, and aging equipment often undermine their effectiveness. This paper presents a systematic approach to FWH optimization by analyzing key operational parameters such as Terminal Temperature Difference (TTD), Drain Cooler Approach (DCA), and extraction pressure. A thermodynamic model was developed to evaluate FWH performance under varying conditions, and parametric optimization was performed. Results demonstrate that maintaining TTD between 5–8°C and DCA between 3–5°C yields significant improvements in efficiency, with potential savings of up to 2–3% in fuel consumption and a corresponding reduction in emissions. The study highlights the role of optimized FWH operation in improving sustainability and cost-effectiveness in modern thermal power plants.
