This course provides a comprehensive understanding of steam turbine lubrication, gland sealing, and drain systems, essential for safe and efficient turbine operation in thermal power plants. It begins with turbine lube oil systems, covering types, bearing lubrication mechanisms, hydrostatic principles, journal and thrust bearings, bearing pedestals, and components of the lubrication system. Learners explore turning, jacking, and main oil systems, including oil pumps, purification, storage, and industry practices for operation and maintenance.

The course covers turbine gland sealing systems, explaining purposes, arrangements, types of seals, rotor gland mechanisms, supporting equipment, circuit operation, and valve stem leak systems. Learners also study turbine drain systems, including operation, protection devices, and types of valves with their construction. Detailed piping layouts, equipment arrangements, and operational considerations are included to ensure reliability and longevity. This specialization equips learners with the skills to manage lubrication, sealing, and drainage effectively, ensuring optimal turbine performance and minimizing mechanical risks in power plant operations.
