Heat Rate Audit In Thermal Power Plant

An initial appraisal of the engine thermal efficiency at full load capacity indicates a heattopower ratio of 1561 representing a thermal efficiency of 391 when calculated on the saturated lower calorific value of the fuel 329 MJm 3 391 MJm 3 dry gross saturated lower calorific value When the engine is operating at part load the gross thermal efficiency falls to
