The purpose of this course is to review the different approaches for applying technologies to the function of cogeneration. We’ll also explore the various issues and considerations for deploymen t of th e two main types of cogeneration concepts: Topping Cycle plants (including Combined Cycle plants), and Bottoming Cycl e plants.
