ConclusionA first law analysis of a thermal power plant has been performed in this studyThe power plants energy efficiency is determined to be 30.12% for the gross generator output by the author, but my calculation was restricted to 27 %.The maximum energy destruction is found to occur in the Air cooled Condenser up to 31 % approx.
