This Course provides a detailed and practical understanding of steam turbine systems and TG (Turbine Generator) island design, construction, and auxiliary systems in thermal and combined cycle power plants. It begins with an overview of steam turbines, covering types, technical features, and combinations of impulse and reaction turbines, along with construction details, axial thrust balancing, casing supports, and material selection. Learners gain in-depth knowledge of turbine auxiliary systems, including feedwater, condensate, extraction steam, and heater drain systems, and their integration within the TG island. The course also covers TG building layouts across multiple floors, including CW and CEP pits, mezzanine, operating, heater, and deaerator levels, as well as combined cycle power plant configurations. Critical piping layouts between boilers and turbines, as well as detailed piping for condensate, feedwater, extraction steam, and heater drain systems, are addressed. This specialization equips learners with the skills to design, construct, and manage steam turbine and TG island systems for efficient, reliable, and safe power plant operation.

Syllabus

Introduction, Energy Scenario and Basic concepts
- This module provides a comprehensive understanding of steam turbine systems, turbine-generator (TG) island auxiliary systems, and plant layout considerations in thermal and combined cycle power plants. It covers the working principles and overview of steam turbines, steam turbine auxiliary systems, feedwater, condensate, extraction steam, and heater drain systems. The module also explains turbine-generator building layouts at different elevations, critical piping arrangements between the boiler and turbine, and piping layouts for condensate, feedwater, extraction steam, and heater drain systems, enabling learners to understand the overall arrangement and integration of steam turbine systems in power plants.
Technical Features and Constructional Details of Steam Turbine
- This module provides detailed knowledge of steam turbine types, operating principles, constructional features, and materials used in power plant applications. It covers different types of steam turbines, impulse and reaction turbine characteristics, combinations of impulse and reaction stages, steam turbine construction, axial thrust balancing methods, casing support arrangements, steam turbines used in combined cycle power plants, and the selection of materials for reliable operation under high temperature and pressure conditions.
