The Evaluation of Steam-Power-Plant Losses by Means of the Entropy-Balance Diagram

This paper deals with a method of isolating and evaluating the various cycle losses of a condensing steam power plant. Each loss in the steam cycle causes an increase of entropy. By considering each of these entropy increases on a “per hour” basis instead of a “per pound” basis, the heat rejection to the condenser caused by each individual loss can be evaluated quickly.
