Thermodynamics of Cogeneration
John
R. White, P.E.
Overview
This three hour online course
explores the thermodynamic aspects of cogeneration (generation of electric power
and utilizing the waste heat for thermal energy needs). It briefly explains
basic thermodynamic concepts in terms that mechanical engineers can grasp, and
provides a refresher for those who have not worked with heat engine cycles for a
while. Carnot and Rankine cycles are described. The importance of
understanding the Second Law of Thermodynamics and applying Second Law analyses
to newly developing energy concepts are stressed. Of particular interest is the
use (and misuse) of the term “thermal efficiency” when discussing cogeneration
cycles. The different “grades” of energy are discussed and the relative values
of electrical energy, thermal and mechanical work.
The
student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.
