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.
