This document describes the layout and components of a steam power plant. It discusses the Rankine cycle used in steam power plants and provides a schematic of the plant layout, including the coal and ash handling plant, steam generator plant, economizer, air preheater, steam turbine, alternator, feed water system, and cooling arrangements. The purpose of each major component in the generation and use of steam to drive the turbine and produce electricity is explained at a high level.

8. Steam generator plant

9. An economizer is a heat exchanger used
for heating the feed water before it enters
the boilers
The purpose of the air preheater is to recover the
heat from the boiler flue gas which increases the
thermal efficiency of the boiler by reducing the
useful heat lost in the flue gas.
