This deceptively simple (at first glance) booklet is actually a fairly comprehensive overview of how a modern coal-fired electric generating station works.
Written towards someone that has a grasp of basic physical concepts, this 16 page booklet is written in easy to understand terms with minimal math. It covers such concepts as steam generation and properties, heat and water recovery, electrical generation methods and simple whole-system overviews.
The reader may not know how every small piece of the system works after reading this, but should have a good grasp of the what and how of electrical generation.
