This paper presents a complete thermodynamic analysis of a typical subcritical steam thermal power plant operating on a regenerative Rankine cycle. Applying both the First and Second Laws of Thermodynamics, an energy and exergy evaluation is conducted to determine the individual component performance and identify the sources of system inefficiencies. Conventional energy analysis indicates that the major energy loss occurs in the condenser due to massive latent heat rejection to the cooling medium. However, exergy analysis reveals that the utmost thermodynamic destruction occurs within the steam generator assembly due to highly irreversible chemical combustion and high-temperature differences occurring during heat transfer. This quantitative analysis of the thermodynamic system establishes that the thermal efficiency of a typical subcritical thermal power plant varies around 32%–40% while its exergy efficiency remains structurally lower. Key strategies such as regenerative feed water optimization and transitioning to ultra-supercritical parameters are discussed as pathways to minimize exergy destruction and also to curtail greenhouse gas emissions.
