Analysis of thermodynamic process of water vapor in boiler

In steam power plant, the working medium used for energy transformation is water vapor. The generation process of vapor has experienced three stages: pre-heat, vaporization and superheat stage. There are five states in process. They sub-cooled liquid, saturated water, liquid-vapour mixture, superheated thermodynamic properties each state usually obtained by using tables charts. constant pressure very common engineering application. general, we first determine parameters charts tables, then make relevant calculations according to law thermodynamics.
