This document summarizes the key components of a thermal power plant, including a coal handling plant, boiler, steam turbine, and auxiliary systems. The boiler system uses a feed water system to provide water and a steam system to control the steam produced. It can use two sources of feed water: condensed steam or makeup water. The steam turbine converts the kinetic energy of steam into rotational mechanical power. Other components discussed include the deaerator, heat exchangers, super heater, condenser, and feed water heater.
