Abstract
The basics of thermodynamics required to evaluate a thermal power plant have been summarized. The first law of thermodynamics and the second law of thermodynamics are overviewed to solve the power plant in view of energy analysis and exergy analysis. The chemical reactions with solutions are explained to understand the solid fuel firing in a typical furnace in a power plant.
Keywords: Combustion of fuels, Exergy, First law of thermodynamics, Second law of thermodynamics.
