This document provides an overview of boilers and the key turbine power plant (KTPP) process. It describes the steps of collecting and handling coal, feeding it into crushers and bunkers, and then mills to power the boiler. The boiler generates steam which powers the steam turbine in three stages - high pressure, intermediate pressure, and low pressure turbines. The turbines convert the steam's heat energy into mechanical energy. Forced draft and induced draft fans are used to control air flow for combustion. Fly ash is removed from flue gases by electrostatic precipitators. Condition monitoring helps avoid forced outages and minimize costs by identifying faults early.
