This document provides instructions for starting up a steam turbine. It outlines the sequence of operations that must be followed, including: opening drains, charging the steam line, starting the cooling water system, operating the condensate system, starting the oil system, putting the turbine on barring, building vacuum, charging gland steam, rolling the turbine, and synchronizing once full speed is reached. Special attention is given to ensuring auxiliary systems are operational and parameters are within limits at each stage to safely start the turbine.

Introduction
Operation of steam turbine is a complex process. Before starting the rolling of a
turbine, auxiliary systems, are to be properly put in service. Special care is required
to be taken for starting of Turbine.
Normally for start up of a turbine some sequence of operation is
followed. We will discuss the operation of different systems as per sequence.
NOTE-:
Don’t do any field activities without informing to control room
